Chapter 137 (2/2)

”Yes, you say.”

”Well...” Shi Yang rubbed his chin and said, ”the first layer - before the experiment starts, clear the principle of each step in his mind.”

”By the time you do it, I've cleared it.” Li Zheng said, ”the first step is to synthesize ethyl coumarin-3-formate from salicylaldehyde and malonate under the catalysis of piperidine. Then alkali is added to hydrolyze the ester group and lactone. Finally, acidification forms a closed loop again to form a lactone, namely Coumarin-3-carboxylic acid.”

”Yes, it's my brother. The theory can. Let's jump to the second level.” Shi Yang said with a smile, ”the second level is to imagine the micro world in the brain, imagine which bond we need to tear up and which bond to form in each step, what kind of influence each reagent will cause in this process, infer the by-products as far as possible, and after all of them have figured out, according to their understanding of chemistry, fine tune the dosage and reaction environment to achieve the highest efficiency. ”

”I fucked...” Li Zheng's eyes glared, and the school movement exploded.

As you draw, you close your eyes.

He tried to imagine himself, into the world of microscopic particles.

In this world, every atom is a point.

These points are bound together by a force called a bond.

When two or more different elements are joined together by a ”key.”.

This is the compound.

What Li Zheng wants to do is to destroy some ”bonds” of existing compounds and stick them to the places he needs.

It's just that he doesn't have the power to do it with his bare hands.

It depends on other substances.

The trouble is that when these substances are mixed together, they tend to cause more side effects, break more bonds, or occupy the points Li Zheng wants to bond.

To this end, Li Zheng tried to imagine every process, every collision between molecules.

How to make them only hit the direction they want.

Come to feel

Combined with Shi Yang's previous skills of piperidine overdose and ice ethanol, this paper discusses the impact of these behaviors on the chemical micro world

Wonderful.

Li Zheng's meditation went deeper and deeper until he penetrated the whole process.

He suddenly opened his eyes.

Then there was the iconic stare.

Learning history has reached its limit. 】

[a total of 26 students were obtained. 】

[academic movement: 4 → 26]

[acquiring talent - Chemical meditation]

[chemical meditation: it can effectively simulate the reaction process of chemical micro world in thinking, so as to design and improve experiments and obtain more experimental inspiration. 】

Shi Yang looked at his wonderful expression and asked in a trembling voice, ”is it so easy to understand, brother?”

”I understand.” Li Zheng can't think more, grabbed the dropper, red Shiyang nodded, ”thank you very much.”

”Ah? I just said a few words casually

”As for.”

In this regard, Li Zheng launched his first experimental journey.

By this time, he had mastered the key points of each process of the experiment.

And have some understanding.

Almost all of them are consistent with Shi Yang's behavior.

This is not a good feeling.

But it is indisputable that Shi Yang's choice is already the limit of the existing knowledge structure.

Li Zheng also made up his mind that the later experiments should never be cheated. He must realize it by himself.
