Chapter 597 Steel Quality Meeting
In fact, the third generation of tear gas also uses explosion to spread more capsaicin. To be honest, the principle is the same as wrapping chili powder on the outside of firecrackers when Gao Zhendong was a child.

Because capsaicin and dihydrocapsaicin, the two types of capsaicin that make up the vast majority of natural and synthetic capsaicin, have a big problem, which is pyrolysis, and this pyrolysis occurs relatively easily.

This pyrolysis can occur in an extremely wide and easily achievable temperature range of 265–425°C. The pyrolysis ratio of the two can be as high as over 90%, and many things can be released, but it is not capsaicin.

This is very good, as it means that the means of generating smoke by thermal dispersion has been essentially cut off.

"As for the third thing, the pepper itself is not enough. How can you eat it if it's not enough to eat?"

Chili peppers require arable land. These days, the priority crops are definitely grains and vegetables. Chili peppers, as a condiment, are not eaten all over the country and are not a necessity, so the yield is naturally not very high.

Haha, this reason is really too powerful.

Lecturer Zhang was shoveling rice into his mouth while thinking, it seemed that there was more than one tear gas agent in Gao Zhendong's meaning.

"Professor Gao, besides OC, what other suitable tear gas is there?"

Well, Citigroup has already made the choice.

Gao Zhendong smiled and said, "I suggest that you can use CS (o-chlorobenzylidenemalononitrile)."

"CS?"

The generations of tear gas are basically based on tear gas. CS is called the second generation of tear gas. Its characteristics are low toxicity and high efficiency compared to CN.

Gao Zhendong roughly explained to Lecturer Zhang: "The Citigroup used to use CN (chloroacetophenone). We suffered a lot from it in the tunnels back then, which is why I considered this thing. But this tear gas has a problem. Inhaling a large amount can be fatal, and the irritation effect is not as good as CS."

At a certain inhalation dose, the main sequelae of CS is dermatitis.

This stimulating effect is the main reason why you chose CS, right? Lecturer Zhang complained in his heart, but did not say it out loud. It would be inappropriate to say such words out loud.

Even though Lecturer Zhang is devoted to academics and not very good at interpersonal communication, he would never say such stupid things.

"Is it expensive? Is it easy to use?" With previous experience, Lecturer Zhang only asked these two questions.

Speaking of this, Gao Zhendong became excited.

"It can be synthesized using o-chlorobenzaldehyde and malononitrile as raw materials."

Well, the name of the reactant here is short, so it should be simpler. Lecturer Zhang, who was slightly shocked by Gao Zhendong's OC "3-methoxy-4-hydroxybenzylamine hydrochloride", quickly learned the simple way of thinking like "choose the shortest among three long and one short".

"It would be best if it could be synthesized directly."

"And it can be synthesized industrially." Gao Zhendong told her the good news.

Industrial synthesis and laboratory synthesis are two different concepts.

Laboratory synthesis means that the thing exists, but whether it can be mass-produced and used is often limited by cost, conditions, environment and other factors, and may not be met.

The most extreme example is those artificial elements with extremely short half-lives, which have to be produced by particle accelerators. Not to mention the high cost and extremely low yield, the short half-lives have to be calculated in milliseconds, so they cannot be used.

Industrialized production means that a large number of target products with stable existence can be produced at one time, which is the tear gas that Lecturer Zhang needs.

"So how do you spread this thing?"

"That's easy. This thing can be made into a smoke-generating type using the heat dispersion method, or into an explosive type using the explosion method, or it can be thrown using a powder spreading device. All are possible."

The ease of use greatly aroused the interest of Lecturer Zhang.

Thermal dispersion and explosive dispersion are her two areas of expertise.

"Professor Gao, this is what I want, this is what I want." It's cheap, can be synthesized industrially, and is easy to use. It's much easier to use than capsaicin.

As for whether it is natural or not, whether it is environmentally friendly or not, I believe no one cares too much. This is a non-lethal weapon, and for this reason, it is already humane enough. Why would you need a bicycle?

"Okay, then you can design it according to CS. As for the specific synthesis process of CS, you can ask me for it when the time comes."

Gao Zhendong knew the synthesis process of this thing, and it was an optimized process with very good cost, yield and product quality.

Although it is not as specific as a process document, the general route, what drugs to use, and what reaction methods are remembered, so I won't waste my chance to search for them. Even though the search price is cheaper now, tear gas is not worth spending money on.

I believe that with these things, comrades in the chemical industry will be able to restore the process of industrial synthesis of CS at a very low cost.

But he couldn't just write it out on the spot, that would be too scary.

Lecturer Zhang didn't care. It was fine to discuss tear gas, but it was inappropriate to discuss the synthesis process of tear gas in the cafeteria. Hey, this thing went too smoothly. I felt like I was taking advantage of Professor Gao.

How about giving him some chili peppers as a test? He seems to like chili peppers.

I just don't know what exactly this Professor Gao does. Judging from his major, it should be mechanical and electrical, but he is also involved in firearms and ammunition. Now it seems that he is even proficient in chemical engineering. It's really amazing.

You should know that Lecturer Zhang originally consulted Gao Zhendong just to get some advice on the spraying method, the type of tear gas, and especially the loading of tear gas.

But she had never expected that he could even obtain the synthesis process of tear gas. No matter how you look at it, this thing should not be something that Professor Gao could know. This major is too broad.

Gao Zhendong: Don’t be too good at basic exercises.
-
Gao Zhendong, who was working at the third factory, received a very rare but funny meeting notice.

The reason why this is rare is that as a member of the 17th Ministry of Machine Building, Gao Zhendong rarely attends the technical meetings of his ministry.

This is why it's so funny. Although he is the winner of many technical awards of the 17th Ministry of Machine Building, he seldom attends the technical meetings of the 17th Ministry of Machine Building. This seems to be an incredible thing no matter what.

Perhaps the leaders of the 17th Ministry of Machine Building thought over and over again and felt that this was a huge loss, so they had to call him up.

The agenda of the meeting was quite interesting, it was a discussion on the steel quality issues of the previous year.

This matter, tsk tsk tsk...

In this regard, Gao Zhendong's idea is relatively simple. He said he can participate, but forget about speaking. I am engaged in new materials, new processes, and new technologies, and I know a little bit about safety, but as for quality, cough cough cough, I am not familiar with it.

Sitting in the conference hall, looking at all kinds of technical experts gathered in the conference hall, Gao Zhendong was hiding quietly in the corner. He didn't communicate about this matter.

The leader of the 17th Ministry of Machine Building saw Gao Zhendong hiding in the corner and smiled slightly. This boy is quite smart and sensitive.

But if you want to hide, ahem, you can't hide.

The leader hasn't called on him yet. This meeting is not just for Gao Zhendong. It would not be good for him to call him out at the beginning.

The meeting went on as usual, with introductions, reports, speeches, and, oh, some cursing as needed.

Well, people at this time are more enthusiastic.

In fact, the matter sounds very simple. The steel production increased significantly last year, but as for the quality, it can be compared to a word that Gao Zhendong often used when talking about steel quality issues in his previous life - substandard steel.

Even substandard steel at least has the word "steel" in its name, but at this time some products are not even qualified as steel.

This problem is not a problem for the Third Rolling Mill, as they are not a steel mill and do not have any steelmaking tasks. However, their limited production of special alloys and some special materials is closely monitored and many people are concerned about it.

Besides, as far as Gao Zhendong knows, those quality problems have basically nothing to do with regular large factories such as Beijing Steel Plant and the Third Rolling Mill.

So he just listened. The discussion was quite lively and many solutions were proposed.

Gao Zhendong listened for a long time and learned a lot. This kind of meeting is really a place to learn things. Everyone who attends the meeting has a lot of knowledge.

When the leaders of the 17th Ministry of Machine Building saw that everyone had said a lot but Gao Zhendong still looked like he was studying hard, they couldn't help but secretly praise this little rascal.

But since he is here, he has to come up with something useful. The leader has no interest in Gao Zhendong's evaluation of the past, nor does he want him to do this, but he wants to hear Gao Zhendong's outlook on the future.

When a comrade finished speaking, the leader of the 17th Ministry of Machinery smiled and tapped the table gently: "Comrade Gao Zhendong, what do you think? Tell me your opinion?"

Gao Zhendong was directly named. As a person who has won more than ten Liehuo Science and Technology Awards, he has not spoken the whole time, which made everyone feel strange. It seems that Chief Engineer Gao is not very active today.

The direct order from the leader of the 17th Ministry of Machine Building made everyone feel that things were somewhat normal. In this situation, something had to be said anyway.

Gao Zhendong had to put down the pen he was using to record. It was not that he was pretending to be diligent, but there were indeed many things worth learning and recording.

It seems that I can’t avoid it, Gao Zhendong thought to himself.

He thought about it, and an idea from long ago came to his mind.

The thing is good, but he didn't dare to take it out before. It was an old problem, inexplicable, the kind that even a genius couldn't explain.

This result can only be obtained by relying on a large amount of actual work experience in the steel industry, collecting a large amount of data, and conducting scientific analysis.

Now there is no problem. This thing looks simple, but it is very useful. It is very instructive for the production process of various steels. It can effectively improve production efficiency and product quality, save costs, and it is very universal.

In Gao Zhendong's previous life, when he talked about people's livelihood, he usually mentioned two basic materials - fertilizer and steel.
