"I confirmed with Aaron on my way here. Currently, there are only seven foreign companies with the production technology for the ring-forming and structure-forming process, and without exception, all of them are member firms of the Wassenaar Agreement."

"If nothing unexpected happens, these seven companies similarly will not provide us with the relevant production equipment."

"So, our only choice at the moment is..."

"To find domestic sources!"

"Domestic?"

Hearing this word, Tian Liangwei was at first startled, then immediately frowned:

"Xiaoxu, the ring-forming and structure-forming processes involve transition metal catalysis and annular skeleton spirocyclization reactions, which are technologies that only began to gradually popularize in 2017."

"Laboratory preparation is certainly not a problem; there are plenty of labs domestically that can achieve it."

"But to add this step to production equipment, it's going to be difficult to find a suitable manufacturer domestically..."

As an executive director of Huadun Biotech, Tian Zhigang also contributed to the company's preparation phase.

Therefore, he knows very well.

In the current domestic chemical manufacturers, there are almost no companies capable of integrating the ring-forming and structure-forming processes into the production line.

Otherwise, they wouldn't have chosen Nutrien initially.

Indeed.

It's not that Huaxia Petrochemical and the like can't break through the technological barriers with significant R&D efforts.

But this kind of custom R&D requires not only a lot of funds but also time that Xu Yun and the others cannot afford to wait for.

According to the plan of Xu Yun and Gu Qunqing.

If they really can't find a suitable company, they can only temporarily use expensive experimental equipment as production containers to forcibly increase the output.

But in that case,

the production cost of "mantis elimination" will be raised to a terrifying figure, and whether there's a yuan profit per finished product is still uncertain.

Therefore, looking at the troubled face of Tian Liangwei, Xu Yun and Gu Qunqing exchanged a glance, and tried to persuade him earnestly:

"Professor, please think carefully again, is there any domestic enterprise capable of achieving this step?"

"It's no problem even if we pay a premium, after all, the money is going to our local enterprises."

Tian Liangwei's eyebrows remained tightly knitted, looking somewhat conflicted.

After a little over half a minute.

He still picked up the mouse and opened a website.

This website is called 'Firesmith', which is an academic BBS under the Chinese Academy of Sciences.

Users can search for some content on it, such as patents or journal progress, as well as some cutting-edge research progress.

As long as you input the relevant information on Firesmith,

content that sits between the third review and the publication phase will be prioritized for display, avoiding collisions.

In short,

website users can understand relevant information earlier than ordinary people without having to wait until the final public stage.

Then Tian Liangwei entered an 11-digit code:

984867...

The initial 98 is the industrial production code, indicating that the search content is in the industrial field rather than laboratory results.

4 is the chemical code.

8 represents non-large-scale containers.

67.... Ahem, further details would end up being reported to the precinct with my ID card...

Moments later.

Two pages of search results appeared in front of Tian Liangwei, with 10 entries per page.

These are all related to the search number, though most are marked as foreign.

Then Tian Liangwei started looking slowly.

He had looked at this search result once more than a week ago and knew the overall situation roughly.

In theory, such a niche technology would not have any big breakthroughs in such a short time, so he was relatively relaxed this time.

But soon.

When scanning through a certain column,

Tian Liangwei suddenly appeared tense.

He uttered a light murmur, leaned forward slightly, and quickly clicked on the secondary link.

A few seconds later.

He suddenly raised his head from the screen and said to Xu Yun:

"Xiaoxu, good news, a state-owned enterprise broke through with Sharpless asymmetric epoxidation production conversion last week!"

Upon hearing this.

Gu Qunqing, due to not being in the same field, was a bit confused, but Xu Yun's pupils shrunk sharply.

In the ring-forming and structure-forming processes, the most challenging processes to industrialize are mainly two.

One is transition metal catalysis.

The second is Sharpless asymmetric epoxidation.

These two processes are standard technologies that are relatively easy in the laboratory but very difficult to industrialize as technological barriers.

After all, the popularity of ring-forming technology itself is not very high, let alone such derivative technologies.

Breaking through either one represents a probability of mastering the whole set of technologies in the short term.

After snapping back to reality,

Xu Yun quickly looked at Tian Liangwei and asked:

"Professor, which factory is it?"

"Sinoma Technology? Or Lu Tai Holding?"

Tian Liangwei gently shook his head and said:

"Neither."

"Neither?"

Xu Yun was immediately taken aback:

"Then who?"

Tian Liangwei turned the screen towards him and said:

"Hanhua Mechanical Group, and the technology was submitted by their factory director, Lin Zhenhua."

......

Note:

This embargo storyline is based on a real event, with the prototype being one of the 18 Arhats, Shenji.

They collaborated on a wave with Qida, and soon you might also see Xu Yun in his book...

One part is the ring-forming and structure-forming production process, the other part is the filling production process.

The former is high-tech, while the latter has relatively low technology.

For the latter, the filling production equipment Xu Yun and others purchased was Modu Chemical's TC708.

The total cost of the entire set of equipment is very low, with the total price of fourteen modules being just over 200,000 Huaxia Coins, along with a three-year technical warranty.

The ring-forming and structure-forming processes involve the production of 10-epoxy-3,6-heneicosadiene, including nickel acetate/sodium borohydride catalytic hydrogenation, Sharpless asymmetric epoxidation, alkyl epoxide rearrangements, and other reactions, so the equipment requirements are very high.
