Chapter 137

"This You've already provided a lot. " Li Zheng hurriedly put on the experimental clothes, gloves, and cleaned the round bottom flask, "then I really did it according to my own understanding."

"I have to do it according to my own understanding. I don't talk all the time, just record." Shi Yangla came to the chair and sat down, turned over her schoolbag with her head down. "The stereotyped routine of memory will only kill your creativity, which is how the elder sister is wasted."

In fact, there is no big problem with what he said.

But Li Zheng suddenly felt a chill in front of the door.

After a sweep.

Shen Yiyun is standing at the door with the material in his arms. His eyes are wide open. It seems that he is going to be totally irritable.

"History..." Li Zheng was so scared that he lowered his head, swallowed and spat and said, "sister Xuejie is just a temporary heavy task Once put into research work, it will be created soon... "

"Hey, no, chemical inspiration doesn't come at once." Shi Yang lowered his head and sighed, "brother, you don't have to think too much about graduate students. Just as they do in the laboratory every day, they can do it by practicing orangutans."

"No No, no, No It's different, brother Shi... " Li Zheng has already started stamping his feet.

"Hey hey, maybe it's better than the orangutan ~" Shi Yang took out Ben and pen and clapped it on the table, and raised his eyes happily, "brother, do you feel that Xuejie has ever made a boyfriend? She is still not... "

"Good afternoon, sister!" Li Zheng suddenly roared and made a salute.

Shi Yang was so scared that he kicked the table and fell to the ground.

Shen Yiyun's face trembled. He walked in with a smile: "Oh, you two are very happy."

"No, no, no..." Shi Yang picked up his glasses and stood up in a panic, "I, I I mean, orangutans are also high-level mammals That is In fact, orangutans are not so different from people... "

Li Zheng said grimly, "brother Shi, say less..."

"Well, you can do whatever you want." Shen Yiyun holding the material to the side of a sit, "I am shallow, or think about how to get along with the orangutan."

Li Zheng said in surprise, "it's none of my business. Don't sit me down together."

Shi yang'er's eyes are staring at each other?

Li Zheng was busy and quietly said: "at least keep one alive..."

"It makes sense I didn't have enough EQ, and I misunderstood it again. " Shi Yang nodded repeatedly.

"All right, I'm going to write a report." Shen Yiyun opened the material and said, "Shi Yang, you are so capable, you can teach Li Zheng."

Li Zheng held down Shi Yang for the first time, and quickly said, "sister, it's not like that. There is still a competitive relationship between Shi Yang and me. It's not convenient to teach me that Shi Yang has to train and test himself

"That's true." Shen Yiyun looked at their collusion and sneered, "well, just that experiment, you do it first, when to achieve 70% yield, when I will teach you."

"Don't put..."

"The 80%

"70, just 70..." Li zhengbusy said, "I really don't have as high talent as Shi Yang. I'll try to do it for once. If my sister has nothing to do, I'll take time to have a look at it. Can I have a tutor at last?"

"Yes." Shen Yiyun waved his hand, "pay attention to safety."

"Good."

Li Zheng was relieved.

"No Brother... " Shi Yang grabs Li Zheng's arm and whispers, "how did you agree? Don't you just light alcohol? For the first time in such a complicated experiment, the yield can be as high as 1%

"Shh." Li Zheng said softly, "you don't understand women."

"Oh?"

"When a woman is angry, she must listen in the opposite direction." Li Zheng put a little bit of his head in a very serious way, "think carefully, if I really do 70% at a time, isn't it even more unnecessary for a senior sister to exist? What else can be directed? "

"Yes Yes... "

"So, sister, this is just a simple angry words, want me to experience the difficulty of the experiment." "As for the results of the experiment, the worse I do, the happier my sister will be and the more she will come to help me," Li Zheng said

"It's tough, brother!" Shi Yangyuan glared at his eyes, "it's really a master. I'm right with you!"

"Don't look proud..." Li Zheng quickly pressed him down again. "Attention, women act according to their emotions. We can't be bullied any more. From now on, the more decadent we are, the better our mood will be. When I make a mess of this experiment, she will naturally smile

"Yes!" Shi Yang repeatedly nodded, "just act like a silly beep, right?"

"Don't deliberately, it's better to make an effort and fail completely. I'm very sincere like a silly beep." Li Zheng then picked up the dropper, "according to what I said before, don't correct me, I'll do it according to my own understanding. The first time I do the experiment, the result will be doomed to failure."

"Well, as I said just now, I'll just record and not speak. I'll discuss it after I've finished." Shi Yang then unfolded the book, rolled up his sleeves and sat down.But he looked at Li Zheng's eagerness to study the scale of the dropper, and he could not bear it: "this Brother, I'd better give you some guiding ideology. Otherwise, it's totally blind. After all, it will take three or four hours to do it. It's not good to waste it like this. "

"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.
