I Have a Research Support System

　　 Although Xu Qiu has compared the system images, today the whole synthesis reaction steps are indeed not missed, but he is still a little vacant, because he saw that the proficiency of the senior is only 50% of the third level.

　　 He regrets a bit, but he should have deduced this skill directly to Tier 5.

　　 However, now that the synthesis reaction has begun, it is done, and nothing can be changed. I can only wait patiently for the reaction to end.

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

　　"The short reaction time is usually done in a microwave reactor, which can be done in a few hours.

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

　　 Generally speaking, the reaction time must be reversed from the product form of the polymerization reaction. If a high molecular weight polymer has been obtained, there is naturally no need to continue.

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

"are you free tomorrow?"

　　 "I will be free tomorrow. There are basically no classes in this semester. You can spend more time doing experiments." Xu Qiu said.

　　 "Okay, let's come over tomorrow morning, do some post-processing, and see if we can vote for a few more new responses." Chen Wanqing said.

　　 Xu Qiu nodded and asked:

　　 "I haven't done the access control for this building yet, where should I do it?"

　　 "I have already managed 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 ID."

　　 Xu Qiu nodded and asked:

　　 "So are there any other experiments today?"

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

　　 "This bucket should be ten liters. We fill about four liters of ethanol, two liters of water, and 300 grams of sodium hydroxide, and stir it until it dissolves."

　　 "Okay, let me do it." Xu Qiu said.

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

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

　　 Xu Qiu put on goggles and other protective equipment.

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

　　 Then, he turned on the tap of the tap water and flushed the outer wall of the plastic bucket with the water to take away the heat generated by the dissolution of the sodium hydroxide.

　　 Next, slowly add flaky sodium hydroxide, about 300 grams, which is three-fifths of the box, which is a good estimate.

　　 Finally, close the lid of the plastic bucket, leaving only a small gap, insert a long glass rod, and stir slowly.

　　 Chen Wanqing was watching, Xu Qiu couldn't find anything wrong with her operation, so she said:

　　 "After the solid matter is completely dissolved, the alkaline tank is made."

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

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

　　 After Chen Wanqing came to check, she said with satisfaction: "Yes, that's it."

　　 "I just went and took a look at the reaction we cast, and it looks normal at the moment. There are already signs of polymerization."

　　 Xu Qiu heard the words and also leaned into his fume hood, opened a corner of the aluminum foil, and observed the changes in the reaction vessel.

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

　　 It seems that the polymerization reaction has indeed started.

　　 "It was past five o'clock, we closed the laboratory and ate in the cafeteria here, and we could catch the school bus at 6:30." Chen Wanqing said:

　　 "No one takes care of the laboratory here, so be sure to check it carefully before leaving."

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

　　"First of all, turn off all equipment that is not in use, especially ovens that can generate heat. It is best to turn off balances and ultrasonic cleaners.

　　 Then, check the water and gas conditions in the laboratory. For condensed water, make sure that the tie is tight to prevent water leakage; for steel cylinders, make sure that the main valve is closed to prevent gas 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 　　, 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 that in terms of laboratory safety, the senior sister is definitely a master." Xu Qiu said.

　　 "Yes, this is also the sequelae of my old mistakes in experiments," Chen Wanqing sighed:

　　 "After all, some experiments are very dangerous, and any mistakes will lead to experimental accidents.

　　 I can't help thinking a lot in the process of doing experiments, which also caused me to do experiments very slowly. "

　　 "I think this is good, personal safety is always the first." Xu Qiu said.

　　 The two took off the protective device~www.wuxiahere.com~ Turn off the lights, close 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 separated from the senior sister, returned to the bedroom, and entered the simulation laboratory.

　　 Now his simulation laboratory is very rich, there are 216 laboratory on the first floor of Handan Materials, room A501-503 of Zhangjiang Microelectronics Building, XRD laboratory, SEM laboratory.

　　 There is also a laptop computer, a large computer in Teacher Wei's office, and a high-performance server copied from the research group of Caiyi217 Pei Zicai.

　　 After checking the existing equipment in the laboratory, Xu Qiu said:

　　 "The system deduces Stilleouhefjyk reaction proficiency to level five."

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

　　 "Deduction."

　　【The deduction is successful. 】

　　 "The system costs 500 points to exchange for a fifth-order Stille coupling reaction teaching, which limits the experimental environment of Zhangjiang Lab A502."

　　【The exchange is successful. 】

　　 A virtual image appears.

　　 This time he defined it to be specific enough. The teaching background in the video is the A502 laboratory.

　　So there is no need to worry about the system using experimental equipment he does not have for teaching.

　　……

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

　　 He skipped the post-processing part first, and it is not used for the time being. If necessary, he will spend points to redeem it.

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