I Am the President of the University

Chapter 433 The mission is here!

Several researchers who had previously refuted Tian Ziang looked at each other.

Isn't this true?

One of them, Sun Jie, stood up with some disagreement.

Although being a Ph.D. student from Wuhan University of Technology is somewhat inconspicuous among the many Ph.D.s from prestigious universities, sometimes one cannot just look at the school.

Wuhan University of Technology is only a 211 university, but in the subject of materials science and engineering, it is rated A+ by the Ministry of Education. There are only three universities in the country that have reached the A+ rating: Tsinghua University, Beijing University of Aeronautics and Astronautics and Wuhan University of Technology.

In the field of materials, Wuhan University of Technology is stronger than Zhejiang University, Harbin Institute of Technology, and Shanghai Jiao Tong University.

"Director, do you think vacuum distillation is feasible? What's the scientific basis?"

Sun Jie's face was neither humble nor arrogant, and he said calmly: "You also often say that you must be down-to-earth in scientific research. You can have certain scientific fantasies, but you cannot be divorced from reality. It is currently recognized in the academic community that the vacuum distillation method only proposes a solution, but there is no solution yet. Which team announced that it had been breached?"

Chen Chong raised his eyebrows, "What Dr. Sun said is good, but since it can be proposed, it must be achievable."

"Professor Fang and I have been discussing this vacuum distillation method for the past two days." Chen Chong said, smiling at Fang Haosen, "Professor Fang, please explain to them this continuous distillation method for purifying lactide. "

"good."

Fang Haosen nodded, then looked around at the researchers in the entire laboratory. When his eyes moved to Tian Ziang, he paused for a moment and looked at him deeply.

When communicating with Chen Chong before, the other party mentioned Tian Ziang several times, but today is indeed different.

Because of the extremely high salary and benefits of Guanghua University, although its overall strength is not high, its scientific researchers are not much lower than those of Chen Hao from the 985 prestigious school.

To be able to put forward different opinions from others among such a group of doctors from famous universities, and also agree with what Chen Chong and Fang Haosen think...

Tian Ziang is the only one!

Before that, Chen Chong had laughed and bet with him that a few people would mention this vacuum distillation method.

Chen Chong guessed 2 people, and he guessed 1 person.

He guessed right, but also wrong.

He originally thought that this person would be Dr. Xia Yao, but he never expected that it would be the sudden rise of Tian Ziang.

"Both academia and industry believe that the vacuum distillation method requires large investment in equipment and high technical requirements, making it difficult to implement. But if you want to prepare lactide with high optical purity and high yield, the vacuum distillation method is the best choice! "

Fang Haosen said with a smile: "The advantage of the distillation method is that it does not require the use of other types of solvents, thus ensuring that no new impurities are introduced during the purification and refining process, and the equipment is easy to scale up and produce continuously."

Sun Jie couldn't help but ask, "Professor Fang, but you also said that the distillation method has high technical requirements and is difficult to implement. This is not practical! "

"Classmate Tian Ziang, do you know who first proposed the continuous distillation method for purifying lactide just mentioned?" Fang Haosen suddenly turned to Tian Ziang.

On the other hand, Chen Chong looked amused.

A few people in the crowd suddenly realized it and felt a little embarrassed.

"Uh... I really don't remember this. What I saw was not the earliest version." Tian Ziang scratched his head and said with some embarrassment.

"This method of continuous distillation and purification of lactide was first proposed by me." Fang Haosen said very calmly, as if he was talking about something inconspicuous.

This was just something he mentioned in his spare time before. He had some ideas at the time, but was delayed and forgotten by things at school later on.

Now it was Sun Jie's turn to be embarrassed. After all, this happened a few years ago, and he had forgotten about it for a while. He didn't expect that the author was in front of his house.

“After discussions between Director Chen and I in the past few days, we have always believed that the continuous distillation method can be used to purify lactide. As for how to implement it, I will explain it to you. "

As soon as Fang Haosen said these words, the ears of everyone below stood up, for fear of missing any word.

Because this will be the most advanced technology in the field of lactide and even biodegradable materials.

“The continuous distillation method for purifying lactide can use a three-tower process.

The first distillation tower operates under vacuum to remove low boiling point components at the top of the tower, the second distillation tower operates under vacuum to remove all meso-lactide at the top of the tower, and the third distillation tower operates under vacuum to obtain high purity at the top of the tower. lactide products, and the lactide yield with a purity of more than 99% will also be higher than 90%! "

The purity is over 99%, and the lactide yield is over 90%!

"hiss……"

I don’t know who took a breath of air-conditioning.

But no one paid attention to this at this time, and many people were still in shock!

The composite solvent multiple recrystallization method mentioned by Xia Yao before is a commonly used purification process in the industry. Because it is easier to operate, the yield is not high, only 35.4%.

90% compared to 35.4%…

This is close to more than double the improvement!

The reason why domestic production capacity of lactide is currently insufficient is that it is blocked by this purification process.

The lactide yield of most biotechnology companies is only 30% to 50%, and the technology is not mature enough to even supply the current Chinese market, let alone after the plastic restriction order is fully implemented next year.

But even Nature Works, the industry leader, announced that the lactide yield is 78.6%, but its unannounced laboratory technology estimates that it has exceeded 80%.

Sun Jie and several researchers next to him looked at each other with disbelief in their eyes.

Sun Jie couldn't help but swallow a lump of saliva. Regarding Professor Fang Haosen's words, if he could really do it, then...

His mouth opened, and he said with some disbelief and trembling: "Then, wouldn't it mean that in the field of lactide and even biodegradation, we will be able to overtake in corners and become the world's leading level...?"

This result is really terrible!

Originally, they thought that if they could break through the lactide technology within a month, they would then conduct further in-depth research to increase the lactide production rate and become the first among domestic peers. The ultimate goal was to solve the problem of insufficient domestic production capacity and dependence on foreign imports. question.

And what Professor Fang Haosen said...

This, this amount of information is too much!

Not only can it solve the problem of foreign companies led by Nature Works, it can also supply domestic polylactic acid raw materials (lactide) while counterattacking abroad and occupying the international market!

You must know that among the several wealth codes in the future, there will be environmental protection!

Environmental protection, elderly care, space exploration, energy... these are definitely one of the mainstreams in the future!

Environmental protection means eliminating existing non-degradable materials and increasing the promotion of degradable materials.

As a new biodegradable material, polylactic acid (PLA) is one of the most popular in academia and industry.

At this time, after receiving everyone's shock, Chen Chong took two steps forward.

He said loudly:

"The president said that our existence at Guanghua University is to solve difficulties."

"Everyone, we can't be followers and run after others. Because we don't have much time! What we have to do is something that ordinary people can't do. It is to lead the technological craze of this era! "

"On our shoulders are the expectations of 1.4 billion compatriots."

Chen Chong clenched his fists in front of his chest, his eyes were heavy and his voice was passionate.

"This is the mission of our Guanghua University!"

ps: Today is the author’s day! After all, the author is just a 300-month-old child. Taking advantage of today's holiday, everyone should call for recommendation votes and monthly votes! (The author has super ferocious bacteria.jpg)

It’s easy to get sleepy while typing in the afternoon... It hurts. I’ve been writing this chapter since five o’clock, and I’m so hungry that I went to have dinner.

The next chapter should be between 10-11 o'clock.
