Chapter 29: A Terrifying 'Little Experiment'

Well, what a 'little experiment'!

Picking up the stack of A4 paper handed to him by Senior Brother Zhong, seeing that it was written slowly, Liu Feng was dumbfounded, took it in his hand and looked at it carefully, it turned out to be just a compound synthesis experiment.

It's just that this experiment seems a bit complicated.

In terms of information, from the very beginning of the experimental equation, the principle and mechanism, and the later experimental procedures, drugs and equipment, precautions, etc., are all available, and the whole set of links is similar to the ordinary synthesis experiments he saw from the experimental book!

It's just that Liu Feng obviously found that the chemistry experiments in the textbooks are only 5 or 6 pages at most, and this experiment, just the equation of the side reactions occupies 5 pages of A4 paper!

Liu Feng felt a little speechless, this is also a small experiment......?

glanced at the experimental data of Chen Hongzhi next to him, and found that the experimental content on it was basically the same.

The two of them stared at each other with big eyes, looking depressed as if they had died of their mother-in-law.

"You take a look first, if there is anything you don't understand, come and ask me, if I am not there, ask Wen Ruonan, I have prepared all the experimental equipment over there, and you two will go over and do the experiment directly later." ”

Zhong Jing handed over the information to the two of them in a chic manner, and was also busy with his own experiments.

That's it, that's it?

Nothing more to say?

MMP!

The two of them held a thick stack of A4 paper and stood at the experimental table in amazement, at a loss. At this time, the two of them had one word in their hearts: messy and messy.

The two of them stared wide-eyed, and they could both see the blankness in each other's eyes.

"Pick it up, what are we going to do next?" Chen Hongzhi swallowed his saliva, checked the information in his hand, and said.

"What to do, of course it's to read the information!" Liu Feng sighed, fortunately, buddy, I have also practiced, otherwise I would be a little helpless.

So the two of them each found a place to sit down, opened the A4 paper and started drying.

Turning from the first page to the last page, fortunately, although this experiment seems to be extremely complicated, most of the writing is the experimental mechanism, side reaction equations, etc., and the part of the experimental procedure that really needs to be operated by him is only two short pages.

Liu Feng first spent more than 10 seconds to memorize these experimental steps, and then memorized the previous mechanism reactions or something, accidentally looked up and saw the difficult brother next to him, but found that this goods were looking sluggish, staring blankly at the long list of compound Chinese names on the first page.

Alas, poor fellow!

Liu Feng shook his head and expressed his deep understanding, after all, when he first saw this, he was also confused!

Chen Hongzhi looked at the information in a daze, and he felt that this was probably the most failed part-time job in his life.

Didn't you say that you only do experiments, what's going on with this thick book?

You know me, but I don't know you!

Although he scored 95 points in the organic bipedal test last semester, with a full score of 100, to be honest, it was also in the top 20 of the grade, and he could be regarded as a top student, but he had really never seen such a complex compound!

The Chinese name alone is enough for three lines, a long list of confusing names, and in the end he can't say what it's really called, anyway, he can't see it clearly.

Looking at the molecular formula of the compound, there are 5 benzene rings on the whole structural formula, and there are 18 other carbon chain branches, what aldehydes, ketones, quinones, alcohols, phenol ethers, etc., almost all kinds of group branches are available!

What the hell is this? Are you sure you can craft it?

Chen Hongzhi lamented, after all, even artemisinin, which is known as the most complex macromolecule seen in college, has such a complex molecular structure!

At this time, Chen Hongzhi's face was loveless, and one word was enough to describe his state at this time: headache!

If it weren't for the shame, he would almost want to give up the struggle and go home!

"Hey, buddy, do you understand?" Chen Hongzhi looked sideways at Liu Feng, and found that this guy was closing his eyes slightly, looking like he was closing his eyes, thinking that Liu Feng was the same as him, and he had completely given up struggling.

Interrupted by Chen Hongzhi's reverie, Liu Feng opened his eyes.

He had already gone through all the information in his mind just now, and it was enough to deal with it: "It's very simple, it's basically the content of organic chemistry books!"

"Jane, simple?" Chen Hongzhi looked at Liu Feng with wide eyes, as if he had seen an alien, "You said this thing is very simple?"

You see, this side reaction is Williamson synthesis, this side reaction is Favorskii rearrangement, and this is the Meerwein-Ponndorf reaction...... You can find the source in the book!"

Liu Feng pointed out the corresponding content in the information, and explained to Chen Hongzhi one by one.

Listening to Liu Feng's eloquent talk, Chen Hongzhi next to him suddenly had an illusion that the person next to him did not seem to be a freshman student, but a knowledgeable teacher, and he seemed to have returned to the freshman and new years, and was watching the teacher spit on the podium with a confused face......

It's just that, if he's not mistaken, Williamson Synthesis obviously started learning it in his sophomore year, right?

And what the hell is Favorskii rearranging? Why doesn't he remember learning it?

Staring at Liu Feng dumbfounded, he just wanted to ask one sentence in his heart, are you a freshman? Are you really a freshman? Are you really sure that you are only a freshman?

"Look, yes, it's all knowledge points that have appeared in books!" Liu Feng looked like he took it for granted, but when he saw this senior brother's dull face, he thought to himself that this guy shouldn't be a scumbag, don't you understand, didn't we waste a lot of saliva just now?

Hurriedly closed his mouth, in this laboratory, there is no pure water to drink: "Speaking of which, Senior Brother Chen is also a sophomore, and he hasn't studied for a long time, so he shouldn't forget it!"

I don't think you will forget it...... But I really can't remember!

Chen Hongzhi's face was flushed, and he almost wanted to die.

No, no, this guy is studying applied chemistry, and I am a polymer material, so the answer must not be that I returned the knowledge to the teacher, but that our textbooks are different, well, it must be......

Then, the guy took a deep breath and silently flipped the data to the experimental protocol.

The previous principle, mechanism, side reactions, etc., it's really terrifying, but fortunately, Lao Tzu is just a simple experiment!

After Liu Feng brushed the entire book, he knew all the principles, mechanisms, side reactions, etc. of this experiment, and he finally had a preliminary understanding of the difficulty of the graduate school's topic.

In Liu Feng's view, the gap between college students and graduate students in terms of theoretical knowledge is not large, and the biggest gap between the two comes from the design and optimization of experimental processes.

For example, the two of them are given an experimental topic at the same time: the synthesis of XX compounds.

When ordinary college students get this topic, they must be confused and at a loss, because they don't know where to start.

What do I need to prepare?

What equipment and medicines do I need?

What difficulties will you encounter?

What can be solved by yourself, and which ones need to be consulted or consulted?

I don't know.

As for the graduate students, after several years of training, they have a clear understanding of the process, so these problems can be solved independently, and deviations can be corrected in time.

As for the theoretical knowledge, to be honest, there is really not much difference from what I learned in college.
