Chapter 354 Talking nonsense, thinking at the same time
Gao Zhendong was in a good mood when he received the call. Listening to Mr. Song talking about the benefits of this fuel on the phone, he was also in a happy mood.
As for whether it is appropriate to chat in a confidential channel? What's inappropriate is discussing rocket fuel, don't make a fuss. Cai always couldn't restrain his joy and asked him to say a few more words.
After finally listening to Mr. Cai’s words, Gao Zhendong couldn’t help but make a joke with him. In fact, it was not a joke, it was the truth.
“Mr. Cai, what do you think is the best way to put out the fire with this thing?”
Such high-energy organic fuel must require very advanced fire-extinguishing methods, right?
Mr. Cai guessed several things. Gao Zhendong said with a smile: "This thing is best for putting out fires, water! Hahaha."
This completely messed up Mr. Cai. Yes, so simple?
I immediately realized, does this mean that the base where this thing is installed does not need special fire extinguishing facilities, equipment and design?
It saves trouble and saves money!
After all, although water is very valuable in some places, it is not as expensive as those weird fire extinguishing agents. Sand is everywhere, but you can't lift it up, and sand is not a good fire extinguishing agent for dimethylhydrazine.
The two chatted and laughed for a while. Gao Zhendong remembered something he had seen before and asked casually: "If the liquid phase chloramine synthesis method is used, what is the yield?"
Mr. Cai was in an excited mood: "It's very high, it can reach more than 45%."
Huh? Is this called very high?
Gao Zhendong has not done any in-depth research and does not know how high the yield of undimethylhydrazine produced in industrial production is. But he had seen data on the laboratory's yield rate, and remembered that it was over 80%.
Not hearing Gao Zhendong's reply, Mr. Cai realized that there might be something wrong.
"Director Gao, is there something wrong with this yield?"
Gao Zhendong pondered for a moment and asked him: "Mr. Cai, is there sodium hypochlorite in the raw materials?"
He had completely forgotten the other things, otherwise he would have just told Mr. Cai last time.
But he remembered this thing, because sodium hypochlorite was the main difference between laboratory and large-scale synthesis, and he was more impressed.
The factory synthesizes liquid chlorine and sodium hydroxide to produce sodium hypochlorite, but the laboratory often uses sodium hypochlorite directly. Maybe this is the difference?
This question stopped Mr. Cai. It’s not that he couldn’t say it. This matter can still be said here by Gao Zhendong.
The main reason is that he doesn’t know either.
He thought for a moment: "Director Gao, I don't know the question you asked. I'll call the researcher over and you can communicate with him. Don't hang up and wait."
Gao Zhendong had been waiting here for less than two minutes when he heard a voice from the other side: "Hello, comrade, I am the researcher responsible for fuel synthesis here."
Neither of them said their names. Gao Zhendong just repeated his question and added: "Theoretically, if sodium hypochlorite is used as the raw material, the yield can reach more than 80%, so I asked Asked. "
Researcher Yue was secretly shocked. He did use sodium hypochlorite as a synthetic raw material. In the laboratory, it is more convenient to directly use sodium hypochlorite than chlorine gas and sodium hydroxide to synthesize sodium hypochlorite. If it is synthesized in large quantities, Then the situation is just the opposite.
The other party was able to name the raw materials he used and the differences between the two. Sure enough, as the person who proposed this fuel choice, it was not easy.
Actually, he didn’t know. Gao Zhendong only vaguely remembered this thing and didn’t know anything else. The main reason was that the productivity in the paper he saw at that time was very high, which was higher than the citations mentioned in the paper. The literature data is more than 30% higher, so it is very impressive.
“Yes, I did use what you mentioned, the molar concentration is.”
As soon as Researcher Yue said this, Gao Zhendong remembered the meeting a few days ago and shouted: "Stop! You don't need to say this, haha. I will only talk about some of my inferences and thoughts. If you think it is useful for reference, just Listen.”
This comrade is quite disciplined, Researcher Yue thought to himself.
"Well, okay, please tell me, I'm ready here."
Gao Zhendong tried to remember, and said slowly: "The higher the reaction temperature, the better, this It is best to control the reaction temperature at 25 degrees. The higher the concentration of the reactants, the better. Based on the concentration of sodium hypochlorite, 0.8mol/L is appropriate. In addition, it is slow."
He only remembered. Speaking of these two numbers, Gao Zhendong was stuck, "sustained release agent"? "Slow response"? Why can't I remember? This thing is too biased. I didn't care at all. I forgot it completely. Did I spend 4 lottery opportunities to find that paper?
However, Researcher Yue immediately solved his tangle: "Comrade, continue talking, I can keep up. You just mentioned the buffer, right?"
After saying this, he was still admiring in his heart, the person opposite Comrade is so considerate. When he talks about key points, he waits for himself to take notes without saying anything. He even stops deliberately to give himself enough time.
Ah, yes, that’s it! Buffer!
Gao Zhendong immediately answered: "Well, okay. The amount of buffer should not be too large, just enough. It is recommended that if conditions permit, take the buffer, reaction temperature, reaction time, reaction Design an orthogonal experiment to see which one is best. I think the yield of your synthesis method should be more than 80%. "Orthogonal experiments use different combinations of conditions to design multiple sets of experiments. , find the factors and their arrangements that have the greatest impact on the experimental results, and combine the best combinations based on the results.
This time I spoke more smoothly, and I only remember so much. I remember that in that paper, I conducted an orthogonal experiment and chose the most suitable combination of conditions.
As for what it was specifically, he didn’t know. The words he just said were a little bit tongue-in-cheek, but he had tried his best.
Fortunately, he didn’t need to remember it. Researcher Yue across from him figured it out on his own. He was a real expert in chemistry.
“Well, comrade, you are right. The chlorination of ammonia by sodium hypochlorite is an exothermic reaction. When the temperature is high, chlorine, ammonia, and chloroammonia will volatilize, which does have an impact on the yield. It’s really great. It won’t work if it’s too low, and it won’t work if it’s too high.”
Gao Zhendong was confused: What did I say? I didn't say anything, it was you who did.
He could only agree with him.
“At this concentration, I considered that the concentration of the reactants is low, it will be difficult to condense dimethylamine and chlorammonium, and it will also be troublesome to distill and concentrate in the later stage, so I increased it a little. I didn’t expect it. I didn’t expect it. Your suggestion is very good. Use the concentration of sodium hypochlorite as the standard to determine the concentration of sodium hypochlorite and use it to determine the concentration of other reactants."
Gao Zhendong: Haha, everything you said is right. Whatever you say is what it is. Is this thing still useful?
In fact, neither of them knew that, regardless of other considerations, the conclusion that the lower the concentration of the unbiased dimethylhydrazine reactant, the higher the yield, is found in foreign literature.
Yeah, but that document was published 4 years later.
Having said this, Researcher Yue was in high spirits: "I will design an orthogonal experiment and be sure to find a suitable combination of conditions."
The reaction condition results in the laboratory provide important guidance for the batch synthesis process. Meaningful, no wonder Researcher Yue is so happy.
"Thank you so much, comrade! Your guidance has been of great help to us. If you have the opportunity, you must come to our place to have a look."
Gao Zhendong: I'm not coming anymore. Come on, I really don’t understand this thing! Come and suffer.
Anyway, the result was good. The two said goodbye with a smile. Mr. Cai took the phone and said goodbye to Gao Zhendong. The confidential call, which was longer than the standard, was cut off. open.
After hanging up the call, Researcher Yue said to Mr. Cai: "This comrade has studied this aspect very deeply. Using a few important core points, he immediately led out the direction and method of improving the synthesis process. If it weren't for Discipline, I have to ask you to tell me who he is and visit him.”
If Gao Zhendong could hear this, he would definitely say: Comrade, please strictly observe discipline!
Mr. Cai smiled and said: "He has indeed made great achievements. If the production rate is high, will the cost be cheaper?"
Researcher Yue smiled: "Of course, if the production rate is high, the cost will be cheaper?" If the rate is increased from 45% to more than 80% as he said, the cost of raw materials will be huge, not to mention other changes brought about by high productivity, such as time saving for the same output, right? The reaction vessel will be smaller, right? These are all state funds."
The two were joking and happily preparing to do experiments.
Gao Zhendong wiped the cold sweat from his head and then laughed again.
Hey, not long ago at the National Defense Work Committee, I learned that some things are really ahead of schedule. Today, from Mr. Cai and the researcher, I can confirm that another thing should also have signs of being ahead of schedule. I'm so happy!
After returning to the office from the confidential room, Director Yan was still waiting for him.
The two of them were having a small meeting just now. Although Housekeeper Yan did not argue with Chief Engineer Gao and shouldered the construction work of the third factory, many things still need to be discussed together by the two of them. I will execute Yes, but you have to nod, right?
Not long after the meeting, Gao Zhendong was asked to leave by the comrades in the confidential room. Director Yan waited for him in his office. Fortunately, the tea here was good, and he would have to find him later. .
Seeing Gao Zhendong come back, the two continued the meeting. They didn't talk much. Gao Zhendong was busy, and Director Yan was even busier. If Gao Zhendong's busyness was something he could control to some extent, then Director Yan was busy. That was completely out of control.
After everything was said and all the signatures were signed, Director Yan packed up the documents and was about to leave when Gao Zhendong remembered something.
"Director Yan, there is something you need to implement. I am at Pudaokou College and have hired three college students who just graduated this year to enrich our technical strength. They will graduate soon. Let's get them Come back."
Director Yan was delighted: "Huh? You can still ask for three students at once? Mr. Gao is awesome, I will implement it immediately."
College students these days, That means students may want to stay, but they may not be able to stay, and the unit may want to, but they may not be able to get it. They are all considered, let alone a student of Wudaokou College.
