The world outside the window is cold and windy, and the occasional few snowflakes that fall are crystal clear, dancing lightly in the cold wind.

On Liu Feng's experimental bench, the electromagnetic heater is constantly dissipating heat like a small sun.

When the thermometer's temperature display reached 100°C, finally, in his vision, the two main raw material molecules collided on a large scale and merged into a new compound.

Liu Feng was overjoyed, could it be that the main reaction was starting to take place?

“1，2，3…… 198, hey, no, there are too many hydrogen atoms!"

Shaking his head, he found that the molecular structure of this new compound was significantly more than the molecular structure of the target compound by several hydrogen atoms, that is, they were not the final product he needed, but still a by-product.

In this regard, Liu Feng was a little disappointed.

After all, every organic synthesis experimenter has exactly the same expectation of the target product as the father's expectation of a new life in the delivery room.

Although disappointed, Liu Feng still recorded this side reaction. Because each recorded phenomenon and side reaction is a cocoon of the whole set of experiments, there is no useless experimental record.

So a new reaction equation was added to the draft book, but in the experimental record book sent by the senior brother, these were not recorded, only some simple experimental phenomena were recorded.

Obviously, this is the clear difference between having a cheat and not having a cheat.

Liu Feng, who is open, can pay attention to the process of the whole set of reactions at any time, whether the side reactions occur, when they occur, and how much they occupy, he can monitor them clearly.

And there is no plug-in experimenter, can only record some simple external reaction phenomena, occasionally through thin layer chromatography or other detection methods, in order to monitor the reaction progress of the target product, this set down, not to mention the time-consuming and laborious cost, the cost is even more expensive, next to Chen Hongzhi and the senior brothers and sisters are like this.

On the other side of the experimental table, Chen Hongzhi was a little bored at this time, his reaction was already on the right track, he had just finished clicking the board and doing monitoring, everything was normal, so he had nothing to do in the next half an hour.

Turning sideways to investigate the information, he saw that Liu Feng had been writing and drawing on scratch paper, and felt very strange.

Organic synthesis experiments are different from other experiments, in the process of carrying out, in fact, there is no need for people to pay attention to all the time, no one can be missed at all; in the synthesis experiment, you only need to occasionally pay attention to whether the reaction temperature, pressure and other indicators are up to standard, at most in a certain time to sample and test, monitor the reaction process.

At this time, it should be very leisurely, what is this guy doing?

"Senior Brother Liu, what are you doing writing and painting there?" Obviously, Chen Hongzhi, who was full of doubts, ran to Liu Feng's side, and looked at him with a curious face.

"It's nothing, idle is idle, just calculate whether there are other side reactions in addition to the side reactions given in the data. Liu Feng said two perfunctory sentences, it was obvious that he would not explain the matter of hanging.

When Liu Feng stopped writing, Chen Hongzhi casually picked up Liu Feng's scratch paper, and when he looked at it, it was full of equations he had written!

I thought to myself, this guy is really a wonder, isn't it just a job, and this experiment will have a dime to do with you after you go back?

Besides, even if you really figure out something, you can make a few more dollars? After all, the senior brother is a big doctor, and I'm afraid that people have already figured out what you are pondering.

Shaking his head and putting down the scratch paper, Chen Hongzhi no longer paid attention to this strange thing, and simply took out his mobile phone and played with it.

How can it be refreshing to read novels!

I heard that the platinum god of Wenyue Group recently opened a new book on the river, which seems to be called the microcosm of the top student?

Let's go, let's go!

……

"Senior Brother Chen, pay attention to your experiments, don't make a mistake with the data!" Not long after Chen Hongzhi took out his mobile phone, Senior Brother Zhong Jing came over to check the post.

"Hehe, senior brother, just put your heart in your stomach! I have already ordered the board just now, and the experiment is normal!" This thing is still reading the novel, fearless.

"Well, it's good to be normal! I'm not saying that you have to keep an eye on the experiment, it's just the key reaction nodes, it's very important, you must not make a mistake for me! Otherwise, it's not easy to explain!" Zhong Jing also knew that the experiment had leisure time, so he turned a blind eye to this guy's mobile phone, "I'll take a look at your experiment records!"

"Okay brother!"

After a few minutes, Zhong Jing checked Chen Hongzhi's experimental records and nodded with satisfaction, it seems that although this guy is a little playful, he is still quite reliable in doing things, at least, he saw that this guy's experimental records are neat, and all the reaction phenomena are also recorded in great detail.

So he came to Liu Feng again.

For Liu Feng, he is really a little worried, after all, this guy is just a freshman, and he really has less experience in doing experiments or anything.

"How is it, junior brother, how is the experiment going?" Zhong Jing also saw that Liu Feng kept writing and drawing on scratch paper, making experimental records, and nodded with satisfaction, this guy is diligent enough!

God rewards hard work, those who help themselves, God helps!

Zhong Jing has always believed that whether a person can succeed or not can be seen from his attitude towards doing things; after all, some experience can still be accumulated, but the attitude of doing things cannot be changed.

Obviously, Zhong Jing was very satisfied with Liu Feng's serious attitude towards doing things.

"The temperature has risen to 110°C, and I just clicked the plate once, and found that the main reaction has not yet started, and I don't know how much the temperature has risen before the reaction starts. Liu Feng directly explained the doubts in his heart to his senior brother.

"Well, this is my negligence! The temperature at which the main reaction starts is about 110°C~130°C, and when it reaches 120°C, you click the plate again, and you may be able to see the target product of the main reaction. ”

"Okay brother!"

"By the way, I saw that you have been recording something on the scratch paper just now, can you tell me about it?" Zhong Jing casually picked up Liu Feng's scratch paper, saw the equations full of them, and said curiously.

"It's such a senior brother!" Liu Feng's eyes lit up when he said the things on the draft paper, and some side reactions were not marked in the information given, but in fact, the results he saw really happened, and the proportion was not small, as for the reason, he didn't understand it very well.

I think that my brother is a graduate student with rich experience, and he should be able to answer: "I observed that one of our starting materials has a branch chain of β-aminoalcohol, so is it possible for it to migrate through carbocation rearrangement C-C and diazotization to form a branch chain with cyclic ketone?"

"Hmm, diazotization? I'll see. Zhong Jing looked thoughtfully at the reaction equation pointed out by Liu Feng, "Impossible." Diazotization needs to be carried out at low temperatures, and our system is a heated reaction, so ......"

The two of them asked and answered one by one.

In the end, the experience of graduate students is much richer than that of undergraduates, except for organic chemistry, Zhong Jing has connected with other content that Liu Feng has not yet brushed up, and answered many of Liu Feng's doubts.

In this regard, Liu Feng was very excited, after all, he, who was a lonely man seeking defeat, finally met a martial arts senior with profound skills worthy of a battle, can he not be excited!

……

There is a lot of talk and laughter, and there is no white ding.

Zhong Jing found that Liu Feng's questions were becoming more difficult and tricky, and he was becoming more and more difficult to deal with, and even many questions could not be answered by him, so he could only excuse himself and say that it was too complicated, so he put it aside for the time being.

Touching his forehead, he really felt that Liu Feng should not be a freshman at all, really, a freshman with this level is not a person!
