1959: Carrying the achievement system, she rolled

But everyone knows that there must be something wrong, but they just have no evidence.

The deceased designer was one of the founders of the aviation industry. He participated in and led the design of many combat aircraft.

His death is a great loss to the country. It should be said that every scientific researcher is a treasure of the country.

When Director Song heard the news, his first reaction was to wonder if his all-powerful Xiao Du would be in danger.

Yu Lang has made the institute's current security issues as solid as an iron barrel, so he is not worried.

His only concern was that she might be in danger if she left the institute, especially during this sensitive period.

Director Wei even gave a strict order, requiring him to persuade Xiao Du not to leave the institute during this period.

After all, she is not a criminal, and even for her safety, her freedom cannot be restricted, so he has to choose his words carefully.

"Director Song, are you saying that someone wants to kill me?" Du Yimeng said with trembling lips. She had expected this a long time ago. Knowing is one thing, and knowing the exact situation is another.

Afraid?

Can she not be afraid?

She might get killed. She is still so young and has a bright future ahead of her.

The most important thing is that she has not yet built the most powerful tank in the world, and she is unwilling to give up.

"Xiao Du, this is just a hypothesis. I'm telling you this because I want you to not leave the institute easily unless it's something important in the near future." Director Song saw that Du Yimeng's face had turned pale, and hurried to comfort him.

He had chosen his words carefully, but how come he still scared people? He shouldn't have done that!

"Don't worry, Director Song, I won't leave the institute during this period." Du Yimeng said. At this time, she had returned to normal.

She couldn't be intimidated by a hypothesis, she had to stay calm. Thinking of this, she was eager to return to the laboratory.

She had to research the new material quickly, if for no other reason than to ensure her own safety.

"You don't have to worry too much. We will definitely ensure your safety." Director Song said. He had asked Director Wei to spread the word that he would be in charge of the institute's work.

It’s not that I want to take credit for her work, after all, the credit has already been given.

Rather, she needed a shield. As for why she didn't let other scientific researchers act as shields, it was simply because those people weren't as strong as him.

Fortunately, for her safety, her identity has been kept secret.

"Director Song, if there is nothing else, I will go back first. The research on new materials has already begun." Du Yimeng said. She didn't want to waste a moment. Wasting time is disrespectful to her own life.

Director Song was filled with emotion as he watched Du Yimeng's departing back. Du was such a good comrade. No matter what time, he always put work first.

Young people like this are the best successors. She is like this, and he believes that there are countless young people like her.

……

From this moment on, Du Yimeng plunged into her busy work again. She would never leave the laboratory until she had developed new materials.

On this day, Du Yimeng, Wanping and Qiao Gong were studying naphtha, which is an important product in petrochemical industry. It can not only produce fuel oils such as gasoline, kerosene, diesel, etc., but also produce solvent oil.

Aromatics can also be obtained through catalytic reforming, mainly due to its composition, which is composed of hydrocarbons.

As for the raw material naphtha, the country had achieved self-sufficiency in oil at that time. The biggest credit came from the successive construction of Shengli Oilfield and Dagang Oilfield, which had already started producing oil.

In that year, domestic crude oil production reached 1131.5 million tons, which also marked an important leap in the history of the development of the oil industry.

Aromatic hydrocarbons can be used to produce paraxylene. In addition, coal tar is also one of the raw materials for producing paraxylene.

Coal-to-aromatics is the process of directly converting synthesis gas into aromatics under catalytic action.

In theory, this is a process route, but in reality, the reaction process is that synthesis gas is first converted into intermediate methanol or olefins under the action of a catalyst.

Then, methanol or ethylene further completes subsequent reactions such as olefin cyclization, dehydrogenation, and hydrogen transfer under the catalysis of molecular sieves to finally produce aromatics.

The disadvantage is that the catalyst has a short lifespan and poor stability.

Paraxylene is an important aromatic organic compound that can be used to produce polyester materials, especially polyethylene terephthalate, which is a commonly used chemical synthetic fiber.

If you don't know what it is, to put it another way, it is also the raw material for making transparent plastic.

Of course, this aromatic organic compound does not meet her requirements and needs to be manufactured into other organic substances later.

The three of them looked at the colorless and transparent liquid in the test tube, and they all saw the excitement in each other's eyes.

At room temperature, it is a colorless transparent liquid with an aromatic smell. It looks beautiful, especially now that it is packed in a transparent test tube, but it is poisonous, with a low toxicity.

It is insoluble in water, but soluble in many organic solvents such as ethanol and ether.

"Record, p-xylene, chemical formula: C8H10, molecular weight: 106.165, melting point: 13.3°C, boiling point: 138.4°C..." When Du Yimeng just said the word "record", Wan Ping had already prepared the notebook and pen.

You should know that Wan Ping's hands were still shaking in the last second, but now they have returned to normal. It can be seen that once he enters the working state, he is a very good working machine.

When each set of data is recorded, this small laboratory will eventually be recorded in history.

Because this technology is not available in China at present, PX production technology was introduced from abroad a few years later.

It can be said that these three people came together to help the country save a lot of foreign exchange.

Even if they fail to develop new materials, based on these data, their efforts over this period of time will not be in vain.

Engineer Qiao, wearing a mask, had his eyes narrowed to a line. If it weren't for the unpleasant smell in the lab, he would have wanted to grin and show off his big white teeth.

Although this research was led by Du Yimeng and he and Wan Ping were his assistants, he was very proud!

Because these two people were students he taught personally, and not only that, they even surpassed him in the field of chemistry, which is pretty good!

He expected that Du Yimeng's ability surpassed his, but he didn't expect that Wan Ping also surpassed him.

He really didn't know what was wrong with this kid's brain. He was like an idiot in other aspects. When everyone was despising him for being stupid, he would try to make up for it in learning the next second.

But when I think of the weird Qin Chulong, it doesn’t seem surprising.
