I Have a Research Support System

Although Xu Qiu compared the system images and found that there were indeed no missing steps in the entire synthesis reaction today, he still felt a little guilty because he saw that the senior sister's proficiency was only 50% of the third level.

He regretted it a little. He should have directly deduced this skill to the fifth level.

However, now that the synthesis reaction has started, it is a done deal, and nothing can be changed. We can only wait patiently for the reaction to end.

Senior sister, how long will our reaction last? I read in the literature that they have various reaction times, ranging from a few hours to a day or two. Xu Qiu said.

The polymerization with a short reaction time is generally done in a microwave reactor, which can be done in a few hours.

With our traditional synthesis method, the normal reaction time is about 24 hours.

Generally, it is still necessary to infer the reaction time from the product form of the polymerization reaction. If a high molecular weight polymer has already been obtained, there is no need to continue.

We are doing experiments across campuses, and it is troublesome to run back and forth, so the reaction time can be flexibly changed according to your own situation. Chen Wanqing said:

Will you be free tomorrow?

I'm free tomorrow. There are basically no classes this semester. You can spend more time doing experiments. Xu Qiu said.

Okay, then let's come over tomorrow morning, do some post-processing, and see if we can post some new responses. Chen Wanqing said.

Xu Qiu nodded and asked:

I haven't done the access control of this building yet, where can I do it?

I've already done your access control for you. Chen Wanqing said:

When you returned the cart just now, I contacted the teacher in charge of access control in the department and reported your student number.

Xu Qiu nodded and asked:

So are there any other experiments today?

Let's prepare another alkali tank, which will be used to clean glass instruments later. Chen Wanqing took out the bucket she had just received and said:

The bucket should be ten liters. We'll fill it with about four liters of ethanol, two liters of water, 300 grams of sodium hydroxide, and just stir it until it dissolves.

Okay, I'll come. Xu Qiu said.

Be careful, the corrosiveness of sodium hydroxide is no joke. Chen Wanqing took out a goggle from the drawer and said:

I forgot to use the goggles just now. This should belong to Duan Yun. You should use this first.

Xu Qiu put on goggles and other protective equipment.

He carried the plastic bucket with the lid to the sink, first added a bucket full of four liters of ethanol to the plastic bucket, then used a one-liter measuring cylinder to roughly measure two liters of tap water, and added it to the bucket.

Then, he turned on the tap water to let the water wash the outer wall of the plastic bucket to take away the heat generated by the subsequent dissolution of the sodium hydroxide.

Then, slowly add sodium hydroxide in flake form, about 300 grams, which is three-fifths of the box, which is relatively easy to estimate.

Finally, cover the plastic bucket, leaving only a small slit, insert a long glass rod, and stir slowly.

Chen Wanqing was watching from the side, and she couldn't find anything wrong with Xu Qiu's operation, so she said:

After the solid matter is completely dissolved, the alkali tank is made.

Xu Qiu nodded, continued to stir, and opened the lid every few minutes to check the dissolution.

Because the amount of alkali added is not high, the dissolution rate is relatively fast. In less than 20 minutes, there is no solid residue in the barrel.

After Chen Wanqing came over to check, she said with satisfaction: That's right, that's it.

I just checked the reaction of our cast again, and it looks normal now, and there are already signs of polymerization.

Hearing this, Xu Qiu went to his fume hood, lifted a corner of the aluminum foil, and observed the changes in the reaction vessel.

Before the reaction started, the state of the monomer dissolved in toluene was a light yellow transparent solution, but now the transparency of the liquid in the bottle decreased significantly, and the color became darker.

It appears that polymerization has indeed started.

It's past five o'clock. We closed the laboratory and had dinner in the cafeteria here, so we can just catch the school bus at half past six. Chen Wanqing said:

The laboratory here is unattended, so be sure to check carefully before leaving.

She took Xu Qiu along to demonstrate and popularize safety knowledge for him:

First of all, turn off all non-use equipment, especially ovens that generate heat, and it is best to turn off balances and ultrasonic cleaners.

Then, check the water and air conditions in the laboratory. If there is condensed water, make sure that the cable ties are tightly tied to prevent water leakage; in the case of steel cylinders, make sure that the main valve is closed to prevent air leakage.

In addition, the glass door of the fume hood should also be pulled to the bottom, so that even if there is a problem with the experimental device inside, it will not spread to the outside.

After that, she walked around the laboratory again and said:

There should be no problem, you can turn off the lights and lock the door.

I feel like my senior is definitely an expert in terms of laboratory safety, Xu Qiu said.

That's right, this is also the sequelae caused by my frequent mistakes in experiments, Chen Wanqing sighed:

After all, some experiments are very dangerous, and once a mistake is made, it will lead to an experimental accident.

In the process of doing experiments, I can't help but think a lot, which also makes my speed of doing experiments very slow.

I think this is very good. Personal safety is always the first priority. Xu Qiu said.

The two took off the protective gear, turned off the lights and closed the door, and after having dinner at the Zhangjiang campus, they took the school bus back to the Handan campus again.

…………

After getting off the school bus, Xu Qiu said goodbye to his senior sister, returned to the dormitory, and entered the simulation laboratory.

Now his simulation laboratory is very rich, including laboratory 216 on the first floor of Handan Materials, rooms A501-503 in Zhangjiang Microelectronics Building, XRD laboratory, and SEM laboratory.

There is also his laptop, a large computer in Mr. Wei's office, and a high-performance server copied from Cai 1 217 Pei Zicai's research group.

After taking stock of the existing equipment in the laboratory, Xu Qiu said:

System, deduce the proficiency of Stilleouhefjyk's reaction to the fifth level.

[To deduce the Stille coupling reaction to the fifth order 0%, 50%*100+1000=1050 points are required. Is it deduced? 】

Deduction.

[The deduction is successful. 】

For the system, spend 500 points to exchange for one fifth-order Stille coupling reaction teaching, and limit the experimental environment of Zhangjiang Laboratory A502.

[Successful exchange. 】

A virtual image appears.

This time he was specific enough, the teaching background in the video is the A502 laboratory.

In this way, there is no need to worry about the system using experimental instruments that he does not have now for teaching.

...

It took more than two hours, and Xu Qiu repeatedly watched the process of the virtual villain's votes and reactions four or five times.

He skipped the post-processing part first, and it is not needed for the time being. If it is needed, then spend points to redeem it.

The overall feeling is that this high-level deduction is worth the money, and he has learned a lot of experimental details from it.

Thanks to Apple Fighter for the 200-point reward, and thanks to ghift and Liu Qigongzi V for the 100-point reward.
