Into Unscientific

"CL20?"

Hearing the word that came out of Xu Yun's mouth.

After Lao Guo's initial astonishment, an idea quickly popped up in his mind:

This half-baked guy is going to make trouble again.

However, Lao Guo's ability to have this kind of thinking is mainly "benefited" from his dealings with Xu Yun many times, and he has seen Xu Yun's unconstrained thinking.

As for Wang Yuan and Gao Yuanming who were beside him at this time, they obviously lacked experience in this area.

Among them, Gao Yuanming looked at Xu Yun in surprise, wondering if he had misheard some syllables, and confirmed again:

"CL20? Consultant Han Li, what is this thing? ——You don't mean CLR21, the incendiary, do you?"

Seeing this, Xu Yun smiled at him, shook his head, and explained:

"Gao Gong, I'm not mistaken, it's CL20—it's the code name for a new type of explosive."

"This is also a kind of material that I heard when I was in Cambridge University. At that time, there was a senior named Seamus Finnigan who was a lover of explosives, and he was very fond of blasting all his life."

"However, he is still not satisfied with the power of the two explosives, TNT and RDX, and has always wanted to develop a high-energy explosive that will explode just by looking at it."

"After detailed research and analysis, he finally came up with a more powerful explosive formula, and named it CL20."

"It's a pity that Senior Seamus died in an explosives experiment later, and the research and development of this CL20 explosive was interrupted. Only some manuscripts remained on the bookshelves of the Cambridge University library."

"A more powerful explosive formula? How is this possible?"

Hearing this, Wang Yuan, who is quite proficient in the research and development of explosives, couldn't help but frowned, and he didn't seem to buy it:

"Consultant Han, you may not be very clear."

"According to the current research results, the known explosives are all ring-shaped molecular structures, and their performance has almost reached the bottleneck, and it is difficult to improve."

"So in theory, there should be no more powerful explosives - even the new explosives we are deploying now, the optimization is just the reaction time."

Wait for Wang Yuan to finish speaking.

Gao Yuanming on the side also nodded.

It was mentioned earlier.

Currently recognized explosives mainly have three generations, namely nitroglycerin, TNT and RDX.

Among them, nitroglycerin was created by Nobel, and its chemical formula is C3H5N3O9. Its detonation speed can reach 7700 meters per second, and its explosive power is 30 times that of traditional gunpowder.

The chemical formula of TNT is CHNO, and its scientific name is trinitrotoluene. Its detonation speed is slower than that of nitroglycerin, but it is more powerful and more stable in nature.

After long-term use and unanimous praise, TNT, like a 1.2-meter novel character, has long been a unit of measurement for measuring released energy.

RDX was created by German chemist Henning. It is called cyclotrimethylene trinitramine, and its chemical formula is C3H6N6O6. It is also called cyclone dynamite, RDX and so on.

The power of RDX is 1.5 times that of TNT, and its detonation speed can reach 8,750 meters per second. It is a well-deserved explosive brother in this period.

But on the other hand, that's the end of it.

Due to the structural limitations of explosive molecules, even RDX cannot further improve its chemical properties.

Therefore, from Wang Yuan and Gao Yuanming's point of view, what Xu Yun said seemed...not quite reasonable.

However, Xu Yun waved his hand indifferently, and pointed to the explosive powder beside everyone, explaining:

"Wang Gong, you are right. The current three generations of explosives may be different in power and stability, but they all belong to the ring molecular structure in structure."

"Within the range of this structure, the power of the explosive has indeed reached the upper limit, and there is no chance to increase it."

"But... what if we broaden our thinking a little further, that is... no longer limited to flat structures?"

Wang Yuan was stunned for a moment, looking a little surprised.

After a while.

His pupils shrank suddenly, and he looked at Xu Yun suddenly, without even noticing that the cigarette on his ear fell to the ground:

"Consultant Han, is it not limited to the flat structure? You mean to expand from the flat to the"

Xu Yun nodded heavily, put his left hand flat on his chest, and drew a circle with his right hand, confirming his guess:

"That's right, if the structure is expanded to three dimensions, then is it possible to increase the bond energy level between molecules?"

"After all, when the structure changes, the energy and tension also change."

chemical bond.

This concept was first proposed in 1916, and then in 1927, Heitler used quantum mechanics to solve the problem of covalent bonds and clarified the nature of chemical bonds.

Although the molecular orbital theory has not been formally proposed, some structural researches have achieved certain results.

Therefore, at this moment, Xu Yun put forward the concept of molecular structure with confidence.

Students who have taken high school chemistry should know it.

From a macro perspective, the explosion of explosives is basically a process of emitting light, heat, and releasing a large amount of gas.

But from a microscopic point of view, that is another matter:

The real face of explosive explosion is the process of breaking the chemical bonds in the original substance and forming new stable chemical bonds.

Such as TNT.

As mentioned above, the chemical formula of TNT is CHNO.

From a structural point of view.

If you remove all the nitro groups (NO) of TNT, what you see is a toluene molecule, that is, a methyl group (CH) is attached to a benzene ring.

A TNT molecule has three divalent nitrogen-oxygen bonds and three monovalent nitrogen-oxygen bonds.

But the monovalent nitrogen-oxygen bond in this structure is not neutral, but has redundant negative and positive charges, respectively.

Therefore, a single TNT molecule cannot exist.

They must rely on other TNT molecules to "neutralize" the extra unstable charge.

When the external energy stimulates the separation between TNT molecules, the negatively charged oxygen atoms on the branches may not "knock" to the positively charged nitrogen atoms, because the carbon-oxygen bond can store more bond energy .

So during the explosion.

The carbon atoms and oxygen atoms in the benzene ring combine to form carbon monoxide.

This is like an accidental product after a man and a woman have sex, so this action directly caused Benzene Huan to collapse the house like Kun Kun, it collapsed into a mess.

Immediately afterwards, the carbon atom from the cleavage of the benzene ring ruthlessly deprives the oxygen in the nitrogen-oxygen double bond.

At this time, nitrogen is just like a small amount of sanity powder. Ahem, it is dissociated, and quickly forms a nitrogen triple bond, which is often called nitrogen N.

In this process, a large amount of heat is released, and the direct separation of methyl CH allows two methyl groups to form two parts of pure carbon and three parts of hydrogen H,

The benzene ring was originally occupied by methyl and nitro groups, and there are 2 hydrogen atoms on each benzene ring.

When the benzene ring "collapses", these two hydrogen atoms are equivalent to brain powder, not only did not fall off the powder, but also combined with each other to form a hydrogen-hydrogen bond, that is, hydrogen encourages each other.

So - 2CHNO→ 12CO + 5H+ 3N+ 2C

In this reaction, the reaction products are gases such as carbon monoxide, hydrogen, and nitrogen. The rapid expansion of the gas explodes with great energy, which is the origin of the power of explosives.

Very simple and very easy to understand.

But on the other hand.

Just like those entertainers whose houses collapsed.

No matter if you are Kunkun (TNT), Fanfan (Hessokin) or Nitroglycerin (Fengfeng), news of collapsed houses is indeed very popular, but it is basically at its peak in the entertainment industry.

Even if Thai pants are hot or the house collapses, the popularity will not be much higher than them. These top streamers have "tested" their power to the maximum.

but

This is just the upper limit of the entertainment industry (planar structure).

for example.

If one day the national football team wins the World Cup, it is estimated that all social media in China will be paralyzed.

This kind of social news is what Xu Yun said.

That is.

The direction of CL20.

The so-called CL20, whose full name is Hexanitrohexaazaisowurtzitane, is also known as the fourth-generation explosive, with a detonation speed as high as 9,500 meters per second, and its power is three times that of TNT.

In the case of the same charge, the bomb using CL-20 will be more powerful than ordinary bombs.

It can even replace tactical nuclear weapons to a large extent, and it can be said to be the best choice for conventional strikes, that is, the sub-nuclear level.

In addition, it can also be used as propellant for missiles. Without changing the size and charge of missiles, its high capability density can greatly increase the range of missiles.

This explosive was first synthesized by Nelson across the sea, but the method proposed by this person has a very serious problem:

It costs $1,000 to produce one kilogram of CL-20, which is ridiculously high.

Therefore, after three years of research on the opposite side of the sea, after being unable to leave the laboratory, it gradually put its research sequence on the back burner.

The theoretical research of the rabbits was a little earlier than that of the opposite side of the sea. In 1979, Academician Yu Yongzhong proposed the feasibility of the theory of high-density materials.

But in the follow-up research and development process, the rabbits also encountered the problem of high cost.

This situation has continued until the 21st century. Huaxia’s Beijing Institute of Technology has made a breakthrough in this area, reducing its cost to one thousand per kilogram. That is, it only costs 1 yuan per gram.

It is precisely because of such a breakthrough that in 2016, the "New Generation of Energetic Materials Research and Engineering" project led by BIT won the Special Prize for National Defense Science and Technology Progress.

As of 2023, when Xu Yun travels through.

The rabbits’ Dongfeng-31A intercontinental missile, Dongfeng-41 intercontinental missile, Changjian-10 cruise missile, etc. all use CL-20 explosives as materials for the warhead or propulsion department.

The core reason why CL20 can have such excellent performance is that its structure has expanded from a plane to a three-dimensional cage structure.

Indeed.

For ordinary people, let alone memorize the structural formula of CL20, I am afraid they have never even seen it.

but don't forget

Xu Yun's work unit in his previous life was Cheng Fei from Rongcheng.

Therefore, for him, the production process of CL20 is not a big secret—in fact, this thing is also semi-public in later generations, because some ingredients are only capable of being produced by rabbits, and they are not afraid of spreading it.

Then Xu Yun glanced at Wang Yuan who was in deep thought, and continued to speak:

"Wang Gong, according to the manuscript left by that senior Ximo, there are two main difficulties in the production process of CL20."

"One is the chromatographic separation of the nitrous solution during the production process. I am afraid that some of the more advanced instruments in the capital will be used for this part."

"The second is the synthesis of the cage precursor, which needs to be realized through aldehyde-amine condensation reaction." (I won't write too much detail on this aspect, refer to the paper 10.16606/j.cnki.issn0253-4320.1998.09.004)

The so-called vertical cage structure refers to the single substance explosive with CH1, 2NO2 structure.

The synthesis method of the caged amine is like the aldehyde-amine condensation reaction mentioned by Xu Yun. The reaction is carried out at 25°C, using acetonitrile and water as solvents, formic acid as a catalyst, and then adding benzylamine and glyoxal.

After the aldehyde and amine are condensed into imines, and the imines are further polymerized to form hexabenzylhexaazaisowurtzitane, the precursor of caged HNIW, some subsequent synthesis can be carried out.

"So so. So so"

It took Xu Yun about ten minutes to recount the general details of the entire process with Wang Yuan and others.

Wang Yuan and Gao Yuanming's eyes became brighter as they listened, and their breathing became faster.

After a few minutes.

Wang Yuan suddenly waved his hand behind him and said:

"Da Liu, Yu, come over here."

Wang Yuan just finished speaking.

Then two men walked up conveniently.

The one on the left of the two is taller, thin and dark-skinned, and looks like a thin bamboo pole.

The one on the right is shorter, with a round face, and his brows are very curved. If he is longer, he can play the Bodhi Patriarch in Journey to the West.

Wait for the two to go up and down.

Wang Yuan patted their shoulders and introduced to Xu Yun:

"Consultant Han Li, let me introduce you, these two are engineers of our team."

"This taller Comrade Liu Zhendong, beside him is Comrade Yu Yongzhong."

"Comrade Liu Zhendong is currently in charge of the research and development of melting molds, and Comrade Yu Yongzhong is in charge of explosive ratio and chemical synthesis."

Liu Zhendong? Yu Yongzhong?

The moment I heard these two names.

Xu Yun was slightly taken aback.

Good guy, isn't this a coincidence?

It was mentioned before.

In the original history, the rabbits spent a lot of time on the construction of the detonation test site, far exceeding the expected time limit.

If it wasn't for an engineer who made a Mikhailov pot like a cheater, the rabbits' atomic bomb would be at least three to four months late to explode.

And the engineer who made Mikhailov's pot was the Liu Zhendong in front of Xu Yun—considering his name and work unit, Xu Yun was 100% sure that the other party was the same person.

As for Yu Yongzhong next to Liu Zhendong, he is also a big boss.

He is the main person in charge of the research and development of explosives and fuel in the two bombs and one star project of the rabbits, and he is also the first explosives engineer who developed CL20 on the rabbit side.

It is the same as Chen Huaijin, Shen Zhongfang and others who appeared in the previous Jade Sword project.

Yu Yongzhong was not selected as an academician not because of his lack of ability, but because his contribution was not officially declassified until recent years.

At the time when Xu Yun traveled through.

Mr. Yu Yongzhong just passed his 99th birthday not long ago, and he will be 100 years old in a year. If he is healthy, he can drive an electric wheelchair to go out for a stroll

Then Xu Yun shook hands with Liu Zhendong and Yu Yongzhong very politely. After letting go, Wang Yuan also introduced the CL20 process that Xu Yun said to them:

"Extend the molecular structure to three-dimensional two-dimensional. Jirigualaabaaba"

A few minutes passed.

Wang Yuan looked at the two of them and asked:

"Zhendong, Yongzhong, what do you think?"
