Chapter 1044: New Gadgets from the Thirteenth Machine Department
It's too detailed, even the pH value is taken into account. It's just that the riddle is a bit confusing.

Being able to provide such detailed information, I think Mr. Gao knows the result well, but why doesn't he just say it directly?
Gao Zhendong shook his head: "You will know when you do it. By the way, you must keep it confidential while doing it. I won't tell you here for this reason."

Teacher Gan and the comrades from the Department of Mining and Metallurgy all guessed something, but they dared neither say it nor believe it.

Chief Engineer Gao, it's too dangerous here! I must forget everything.

Looking at their expressions, Gao Zhendong laughed: "Not really, it's just one of the ways, but it's far from practical. The reason why I specifically mentioned it is just because it's very special and interesting."

No, Mr. Gao, it may just be something interesting in your eyes, but it is a huge topic for us!

Another reason why Gao Zhendong specifically brought up this matter was that the metals chelated by this route had a great impact on the later development of Shu Province. It was also like paving the way for comrades in advance. Otherwise, it would have been a waste to wait until more than 20 years before getting preliminary results.

"Okay, Mr. Gao, we will definitely pay attention to it!" The comrades from the Mining and Metallurgy Department and Teacher Gan looked at each other and decided to file this matter with the unit's confidentiality committee. No! They would just find a relevant unit in Beijing to file it.

Although there was a slight suspicion that they were being tricked, the two of them wished there were as many such traps as possible.

It took some more time for Gao Zhendong to tell Teacher Gan everything he knew about amidoxime chelating resin, and Teacher Gan also took notes for many pages.

There are even many structural formulas and schematic diagrams drawn by Gao Zhendong himself.

I made a fortune! At this time, Teacher Gan was very proud. This small notebook in his hand was enough for him and his schoolmates with similar majors to make money for ten or twenty years. After all, it was not enough to make it. It also needed mass production and subsequent improvements...

The content at hand is really too rich.

Seeing that he had written everything down, Gao Zhendong said something that made Teacher Gan almost vomit blood.

"Okay, I have introduced the general background technology to you. Now let's discuss the use of amidoxime chelating resin to extract gallium and indium..."

The two people in front of him suddenly had an urge to fall to the ground.

So after all this talk, we are still just preparing? Isn't this preparation a bit too long?

I originally thought that Chief Engineer Gao wanted them to find the most suitable route for extracting gallium and indium through experiments among so many routes, but I didn't expect that this was not the case at all.

"Chief Engineer Gao, have you studied how to use chelating resin to extract gallium and indium?" Judging from how familiar he is with the special metal just now, wouldn't he be even more familiar with gallium and indium, the protagonists of this time?

Gao Zhendong waved his hand: "It doesn't count as research. It's just some thoughts and inferences. It's not confirmed yet. The subsequent implementation work still depends on you, hehe."

Gao Zhendong's smile was a bit scary, at least that was how Teacher Gan felt. How did Chief Engineer Gao come up with so many routes that at least seemed relatively reliable and a few special technical details?

Don't just think it looks reliable. To be able to think of this step with your brain means you are an absolute genius in organic chemistry.

"If you use amidoxime resin, you can consider selective adsorption in a solution with a pH value of 2-3, then elute with 1-6 mol/L inorganic acid, and then further treat the eluate. But I am only considering the possibility of adsorption under such conditions. The specific adsorption effect is what you need to study," said Gao Zhendong.

His words once again made Teacher Gan's scalp tingle, because he very keenly heard a word - "if".

What if there is no “if”? Does Chief Engineer Gao have something else to say?
"Chief Engineer Gao, you just mentioned that if we use amidoxime, what if we don't do a good job of using amidoxime?" asked Teacher Gan.

"Ah... I have thought about this question before. If you are interested, we can discuss it..."

Teacher Gan shook his head desperately: "Let's not discuss it. I'll just listen. I don't have any knowledge reserves in this area at all."

Gao Zhendong didn't care. It's okay. After today, you and our chemical industry will have knowledge reserves and prospects in this regard.

"You can consider hydroxyphosphonic acid resin, methylenephosphonic acid resin, aminomethylenephosphonic acid resin, aminomethyl resin, iminodiacetic acid resin, and iminodiacetic acid resin. Among them, the focus is on iminodiacetic acid resin. However, I have not considered the preparation and modification of these resins. You may have to explore it on your own."

This was also copied by him, and he copied it very well. Decades later, imidediacetic acid resin was the most commonly used commercial resin in this regard.

Gao Zhendong also thoughtfully wrote out "亚氨" and "亚胺". These two are easy to confuse if you only listen to them, although one is pronounced in the first tone and the other in the fourth tone. By the way, they also have a brother pronounced in the third tone - 氨.

Gao Zhendong's words made Teacher Gan want to turn around and leave, mainly because it was really discouraging.

"Mr. Gao, let us consider the remaining work. Let us consider it." Teacher Gan and the comrades from the Mining and Metallurgy Department looked ashamed.

It was fine that he helped me think about a lot of details because of his interest in amidoxime, but it was a bit too much for him to ask Chief Engineer Gao for details in other areas. But how this comrade who worked on steel in a steel mill was so familiar with organic chemistry was beyond the ability of Teacher Gan to figure out.

"Well, that's about it. All the capital has been drained out. There's no more." Gao Zhendong laughed.

"That's enough, Chief Engineer Gao. Just these two hours of content are enough for us to work on for at least ten years." Teacher Gan said with a smile.

Gao Zhendong was not in a hurry either: "Well, you don't have to rush about this matter, take your time. There are other technological means to extract gallium and indium now. Although they are not the best, they can be used. However, they are somewhat toxic and cost more."

"Okay, I understand." Hearing this, Teacher Gan did not say anything big, but secretly made up his mind to develop the chelating resin as soon as possible so that the comrades producing gallium can get rid of the toxic production environment as soon as possible.

As soon as Teacher Gan and the comrades from the Mining and Metallurgy Department left Gao Zhendong's office, the comrades from the Mining and Metallurgy Department took Teacher Gan to find the Internal Security Department of the Third Factory.

He had been here twice and had more guesses about the comrades in the Internal Security Department and the nature of their work.

"Comrade, I have a situation that I want to report and file. It has something to do with confidentiality. Who can I contact?"

The comrade from the Internal Security Section of the Third Factory was familiar with the matter: "What about this? Come on, come with me. There are comrades in charge of related work over here."

That evening, the leaders of the Defense Work Committee received the news.

Looking at the situation report brought up by his comrade, he also had a toothache expression on his face: "Sure enough, no matter how many precautions we take, we still can't prevent it. Inform these two comrades to standardize the process of that work in accordance with the highest level of confidentiality requirements. We will also provide relevant cooperation."

The chief engineer of the Defense Works Committee looked at him and smiled, "What metal do you think it should be?"

"I don't know. Gao Zhendong is so mysterious. Why don't you go and ask him? But I think you should have some guesses, right?"

"Yes, but I think this is going too far. Forget it, just keep it a secret and think of it as joining him in some fooling around. Besides, asking now is not a good idea. If you don't know about some things, you can make no arrangements. If you really know, you can't make no arrangements."

The leader nodded and said, "Well, your consideration is correct. If it is really as we guessed, then we really can't reveal it now. Inform the comrades in charge of the relevant work to ensure confidentiality."

After saying that, he shook his head and laughed helplessly.
-
Time continues to pass day by day, and more and more results are achieved on all fronts.

One day in March, just after Gao Zhendong started working, a deputy chief engineer of the 3th Ministry of Machine Building came to invite him personally.

"Chief Engineer Gao, come on, we would like to invite you to visit our department and give us some suggestions. Don't worry, all the procedures have been completed." They were all deputy chief engineers of the same department, so the man from the Thirteenth Machine Department was also very casual, which was just right.

Gao Zhendong walked out with him and asked with a smile: "What's the good news?"

"You'll know when you get there. You'll definitely like it. That's your own child, hahaha. Come on, come on, our department's leaders and chief engineers are rushing over there, waiting for you." Deputy Chief Engineer Tao of the Thirteenth Machine Department really likes to joke.

The two men drove one after the other to the Beijing Automobile Factory under the Thirteenth Ministry of Machine Building, which was also one of the first automobile factories.

Gao Zhendong looked at the Beijing Automobile Factory's brand and sighed. The cars produced by this factory became famous decades later, but the quality of their assembly was also famous, even though it was a product of one of its subsidiaries.

Their jeep is a classic, but as for the quality...it's said that you have to tighten the screws yourself before buying it.

Gao Zhendong shook his head and walked into a workshop with Deputy Chief Engineer Tao.

Two cars were quietly placed in the workshop, one covered with a cloth and the other not. However, the shell of the uncovered car was one that Gao Zhendong had seen before. It was a replica of a foreign car.

This is?

Before Gao Zhendong could come out of his confusion, the leader of the 13th Ministry of Machine Building had already walked up to him.

"Comrade Zhendong, you're finally here. We've been waiting for you. Come and see our latest achievements!" He pointed to the uncovered car.

Gao Zhendong was too embarrassed to say that this thing was not new, he just laughed it off.

As if knowing the doubts in his heart, the leader of the Thirteenth Machine Department personally walked to the side of the car and lifted the engine hood: "Come, take a look, this is your hard work!"
