Well, it's really a 'small experiment'!

After taking the stack of A4 paper handed to him by Senior Brother Zhong, Liu Feng was stunned when he saw the writing on it slowly. He held it in his hand and looked it carefully. It turned out to be just an experiment on synthesis of compounds.

But this experiment looks a bit complicated.

In terms of data, everything is available from the initial experimental equations, principles and mechanisms, as well as the subsequent experimental steps, pharmaceutical equipment, precautions, etc., and the whole set of links is similar to the ordinary synthetic experiments he saw in the experimental book!

However, Liu Feng obviously found that the chemistry experiments in the textbooks and textbooks were only 5 or 6 pages of paper, and this experiment, just the equation of side reactions actually occupied 5 pages of A4 paper!

Liu Feng felt speechless. This was also a small experiment? The time is still the same...

I glanced at the experimental data from Chen Hongzhi next to me and found that the experimental content above was basically the same.

The two of them stared at each other with a frustrated look as if their mother-in-law had died.

"You can take a look first. If you don't understand anything, please ask me. If I'm not here, I'll ask Wen Ruonan. I've prepared all the experimental equipment there. You can do it directly after you go there."

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

That's it, that's it?

There is nothing to say?

MMP!

The two of them stood at the experiment table in shock with a thick stack of A4 paper, at a loss. At this time, they each had a word in their hearts: Ling, Luan.

Both of them stared at each other's eyes, and they could see the confusion in each other's eyes.

"Continue, what are we going to do next?" Chen Hongzhi swallowed, weighed the information in his hand, and said.

"What are you doing? Of course you are looking at the information!" Liu Feng sighed. Fortunately, I have practiced my buddy, otherwise I would be a little helpless.

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

Turning from the first page to the last page, fortunately, although this experiment seems extremely complicated, most of the writing is about experimental mechanisms, side reaction equations, etc. The experimental steps that really require him to operate are only two short pages.

Liu Feng first took more than 10 seconds to memorize these experimental steps, and then remember the previous mechanism reactions and other things. He accidentally looked up and saw the brother in distress next to him, but found that this guy was staring at the long list of compounds on the first page with his eyes blank.

Alas, poor guy!

Liu Feng shook his head and expressed his deep understanding. After all, when he saw this at the beginning, he was confused!

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

Didn’t it be agreed that it would only do experiments? What’s going on with this thick book of information?

You know me, but I don’t know you!

Although he scored 95 points in the Organic Two last semester, and the full score was 100. In fact, it was the top 20 in the grade, and he could be considered a top student in all sizes, but he had never seen such a complex compound before!

The Chinese name alone has three lines, a long list of confused names, and in the end it can't be said what it really is. Anyway, he can't see clearly.

Let’s look at the molecular formula of the compound. The entire structural formula actually contains 5 benzene rings, and there are 18 other carbon chain branches, such as aldehyde, ketone quinone, alcohol phenol ether, etc., and almost all kinds of branch chains!

What the hell is this? Are you sure it can be synthesized?

Chen Hongzhi lamented that after all, even artemisinin, which is known as the most complex macromolecule seen in universities, has less complex molecular structure!

At this time, Chen Hongzhi looked desperate, and one word was enough to describe his current state: a headache!

If he hadn't felt embarrassed, he would have almost wanted to give up struggling and go home!

"Hey, buddy, do you understand?" Chen Hongzhi looked sideways at Liu Feng, and found that the guy was slightly closed, looking at rest with his eyes closed. He thought Liu Feng was like him, and completely gave up struggling.

After being interrupted by Chen Hongzhi, Liu Feng opened his eyes.

He had just passed all the information in his mind, which was enough to deal with it: "It's very simple, it's basically the contents of organic chemistry books!"

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

"Yes, although it looks very complicated, it is actually all about the content of university organic chemistry when it is broken down! You see, this side reaction is Williamson? Synthesis, this side reaction is Favorskii? Rearrangement, here is 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 talk, Chen Hongzhi next to him suddenly had an illusion that the person beside him did not look like a freshman, but a knowledgeable teacher. And he seemed to have returned to the time of a young newbie, watching the teacher spitting on the podium in a confused manner...

But if he remembers correctly, Williamson? The synthesis method was obviously started in his sophomore year. Do you know this?

And Favorskii? What the hell is rearrangement? Why doesn’t he remember learning it?

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

"Look, right? They are all knowledge points that have appeared in books!" Liu Feng looked as if he was taken for granted, but saw the dull face of the senior brother, thinking that this guy would be a bad student, he didn't understand. Didn't we just wasted a lot of saliva?

He quickly closed his mouth. There was no pure water in this laboratory: "Speaking of this, Senior Brother Chen is also a sophomore. He has just studied for a while, so he probably won't forget it!"

I probably won't forget it...but I really can't remember it!

Chen Hongzhi's face turned red, and he almost wanted to die.

No, no, this guy is studying applied chemistry, and I am from polymer materials, 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 turned the information to the experimental steps.

The previous principles, mechanism and side reactions are so terrifying. Fortunately, I am just a simple experiment!

After Liu Feng copied the entire material, he understood all the principles, mechanisms, and side effects of this experiment. He could see the whole story. He finally had a preliminary understanding of the difficulty of the graduate students' subjects.

In Liu Feng's view, the gap between college students and graduate students in theoretical knowledge is actually not big. The biggest gap between the two is still the design and optimization of the experimental process.

For example, both of them got an experimental topic at the same time: the synthesis of XX compounds.

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

What preparations are needed?

What instruments and medicines are needed?

What difficulties will be encountered in it?

What can be solved by yourself, and what do you need to consult information or ask a tutor?

Don't know.

As for graduate students, after several years of training, they have a clearer understanding of the process here, so these problems can be solved independently and can be corrected in a timely manner when there are deviations.

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