i was the president of the university

Chapter 433 Where is the Mission!
Several researchers who had previously refuted Tian Ziang looked at each other in blank dismay.

Isn't this the truth?
One of them, Sun Jie, stood up with some disapproval.

Although being a doctor of Wuhan University of Technology is a bit inconspicuous among all the doctors of prestigious universities, sometimes you can't just look at the school.

Wuhan University of Technology is only a 211 university, but in the subject of materials science and engineering, the Ministry of Education has rated A+, and there are only three universities in the country that have reached A+: Tsinghua University, BJ Aerospace University 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 Jiaotong University.

"Director, do you think the vacuum distillation method is feasible? What about the scientific basis?"

Sun Jie's face was neither humble nor overbearing, and he said in a calm voice: "You also often say that scientific research must be down-to-earth. You can have certain scientific fantasies, but you can't be divorced from reality. The current academic circles generally recognize that the vacuum distillation method is only a solution, but it has not yet Which team declares it has been breached."

Chen Chong raised his eyebrows, "Dr. Sun's words are not bad, but since it can be brought up, it must be achievable."

"Professor Fang and I have been discussing this vacuum distillation method for the past two days." As he spoke, Chen Chong smiled slightly at Fang Haosen, "Professor Fang, please explain to them the method of continuous distillation to purify lactide. "

"it is good."

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

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

Guanghua University has extremely high salaries. Although its overall strength is not high, its scientific research personnel are not much lower than Chen Hao, a famous 985 university.

To be able to put forward an opinion that is different from others among such a bunch of doctors from prestigious schools, and it is still consistent with Chen Chong and Fang Haosen...

Only Tian Ziang is alone!
Before that, Chen Chong even made a bet with him with a smile on how many people would mention this vacuum distillation method.

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

He guessed right, but also guessed wrong.

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

"Academic and industrial circles believe that vacuum distillation equipment is expensive and technically demanding, and it is difficult to realize. But if you want to prepare lactide with high optical purity and high yield, vacuum distillation 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 will be introduced during the purification process, and the equipment is easy to scale up and produce continuously."

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

"Student Tian Ziang, do you know who first proposed the method of continuous distillation and purification of lactide?" Fang Haosen suddenly turned to Tian Ziang.

On the other hand, Chen Chong looked funny.

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

"Uh... I really don't remember this, I didn't read 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 saying something inconspicuous.

This was just mentioned in his spare time before. He had some ideas at that time, but he was delayed by the school affairs later and forgot.

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

"After discussing with Director Chen in the past few days, we have always believed that continuous distillation and purification of lactide can be used in the purification process of lactide. As for how to implement it, I will give you a good talk. "

As soon as Fang Haosen said this, the ears of everyone below were pricked up, for fear of missing any word.

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

"Continuous distillation and purification of lactide can use a three-tower process.

The vacuum operation of the first rectification column removes low boiling point components at the top of the column, the vacuum operation of the second rectification column removes all meso-lactide at the top of the column, and the vacuum operation of the third rectification column obtains high purity at the top of the column Lactide products, and the yield of lactide 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 cold air.

But at this time, no one pays attention to this, and many people are still in shock!
The complex solvent multiple recrystallization method mentioned by Xia Yao before is a purification process commonly used in the industry. Because it is relatively easy to operate, the yield is not high, only 35.4%.

90% compared to 35.4%…

This is close to more than doubling the increase!

The reason why the current production capacity of lactide in China is insufficient is that it is blocked by this purification process.

The lactide production rate of most biotechnology companies is only 30%-50%, and the technology is not mature enough to even supply the current Chinese market, let alone after the full implementation of the year-end plastic plastic order.

But even for Nature Works, a leading company in the industry, the announced yield of lactide is 78.6%, but the unpublished laboratory technology is estimated to have exceeded 80%.

Sun Jie and several researchers next to him looked at each other, their eyes full of disbelief.

Sun Jie couldn't help swallowing his saliva. Regarding what Professor Fang Haosen said, if he could really do it, then...

He opened his mouth, and said tremblingly with some disbelief: "Then, isn't that in the field of lactide and even biodegradation, we will be able to achieve cornering overtaking 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 one month, and then conduct further in-depth research, increase the yield of lactide, and become the first in the domestic industry. The ultimate goal is to solve the problem of insufficient domestic production capacity and relying on foreign imports. question.

And what Professor Fang Haosen said...

This, this is too much information!

Not only can it solve foreign problems led by Nature Works, it can also counterattack foreign countries and occupy the international market while supplying domestic polylactic acid raw materials (lactide)!

You know, among the next few wealth codes, there is environmental protection!

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

And environmental protection is to eliminate the existing non-degradable materials, while increasing the promotion of degradable materials.

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

At this time, after everyone was shocked, Chen Chong took two steps forward.

He said loudly:

"The principal said that the existence of our Guanghua University is to solve the predicament."

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

"On our shoulders are the expectations of 14 billion compatriots."

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

"This is the mission of our Guanghua University!"
