"It should be fine." In fact, Yang Rui didn't dare to guarantee that when he was in college, because the school was founded by the Germans, he had a natural affinity with Germany, and many students who studied in Germany studied in preparatory classes here, but this era was not familiar to him, and said: "We'll go to the consulate another day to ask." By the way, I said that German universities do not have tuition fees. If you have good grades, you should have a scholarship, and you just need to have travel expenses. ”

Zhong Guan was a little excited when he heard this, and stood up and walked around in front of Yang Rui. Yang Rui laughed when he saw this, and said: "What are you in a hurry, you haven't learned German, it's still early to go to Germany." ”

Zhong Guanguan sat down, calmed down for a while, and then asked, "By the way, I see that the method you just calculated is very strange, is it a way to calculate the true weight of the reactant?" ”

Yang Rui said in his heart, you are so smart, now I am using moL to calculate. He replied, "Yes." It is a unit used to calculate the mass of a reactive substance. After speaking, he paused, and his mind was trying to figure out how to make up the origin of this unit that only appeared sixty years later. When I finally thought about it, I began to tell the story: "I didn't read until I was in middle school abroad, and then I often went to the university to listen to professors' lectures, and once I met an old man on the street, I guess he was a professor or something, and when I saw that he was pitiful, I sent him home, and then I took care of him for a few years, and he taught me a lot of things, and then one day he suddenly disappeared, I guess it was ......"

Something like the Romance of Xianxia is very desirable, Zhong Guanguan said: "Ah." Brother Cheng actually had such an adventure, so what happened later, didn't you ask who he was? ”

"Nope." Yang Rui pretended to be regretful and said: "I only call him Moore, like a European, I don't know why he fell into that like that in the United States, I guess I have some bad experience." Yang Rui's lie is very relaxed, it seems that there are flaws everywhere, but there are no flaws, he is also in order not to let others doubt his origins, so he made it up like this, so that after the story spread, Chinese students abroad respect the old and love the young, which he did not expect.

In the early hours of the morning, after the acidification was completed, they got more than 700 grams of glutamate, and the two of them didn't want to sleep in the excitement, and then finished the real yàn in the back, and finally precipitated the monosodium glutamate. Zhong Guanguan looked at these white things that he had worked hard for overnight, and was very curious, seeing that Yang Rui was calculating something, he didn't bother, and put away the previous things. Yang Rui finished the calculation, put the report away, and then under Zhong Guanguan's surprised eyes, put the white thing into his mouth, he also learned to get a little bit and put it in his mouth, as soon as the thing entered his mouth, he suddenly felt that a umami was generated in his tongue, and he asked: "What is this, feel a umami?" ”

Yang Rui tasted this MSG and was very excited. Seeing him ask, "This is called monosodium glutamate." ”

"MSG," Zhong Guanguan said silently, nodding his head, "Such a delicious taste, it is indeed MSG." If you put it in the dish, then the taste of the dish will be different. "Zhong Guanguan, this is to say the role of MSG.

Yang Rui said: "I wasn't hungry just now, but now I'm hungry when I hear you say food, but unfortunately I can't go out now, and I don't have supper to eat." "There is a curfew at 12 o'clock in the evening in the concession, and the general shops are closed, where can I find food. Yang Rui couldn't help but feel worried. Zhong Guanguan was also hungry, so he took Yang Rui to the kitchen, and when he saw noodles, he started to cook noodles, and some monosodium glutamate was added to the cooked noodles, and the taste was not ordinarily good.

At ten o'clock the next day, Yang Rui woke up in a daze, last night was spent in the Zhong Sightseeing Room, although their instrument hall has many shops and attics, but there is no cover, so they can only sleep with Zhong Guanguan. I slept very sweetly last night. After all, what I've been thinking about for a long time is finally done. It's sunny outside, and it's a good day. The instrument hall is still doing prosperous business, and Yu Huizu and others are very busy. Zhong Guanguan got up first today, and when Yang Rui entered the real room, he was studying how to better precipitate glutamate. He's a chemist.

Yang Rui went back to Ruyi first, took some important things away, and said hello to Mrs. Huang, saying that he would make something at a friend's place in the past few days and would not come back to live. In the next few days, Yang Rui and Zhong Guanguan squatted in the attic room, Yu Huizu was also not surprised, looking for a guy to arrange room and board, and Yu Zixun often ran over to see the two of them when he had nothing to do, and several students from the physical and chemical training institute opened by the Science and Technology Museum have been helping out nearly 100 times in four or five days, and finally explored some key processes, the optimal conditions of the reactive substances and the number of reactive substances are also clear, and it can be said that what can be done in the real yàn room is basically completedThe rest is the question of how to industrialize production.

Because it involves strong acids and high temperatures, as well as cooling precipitation, these process soil methods may be used, but the cost is too great, and at the same time, it will cause unstable product quality. At this point, Zhong Sightseeing has a very profound lesson, and this is how the yellow phosphorus plant collapsed in the past. And Yang Rui is not to mention a half bucket of water, and it is still a small half bucket, and there is no good way, so it seems that he can only find another way to achieve industrial production.

Zhong Guan said: "If you really want to make it like what Cheng said, I can't help it." I think it's better to invite Mr. Xu. ”

Who is Mr. Xu? Yang Rui didn't know why, and asked, "Who are you talking about, Mr. Xu?" He knows chemistry? ”

Zhong Guanguan smiled: "Of course I understand." Does Mr. Yukimura know? Dizzy, another Mr. Snow Village came out, Yang Rui was even more confused, he surrendered: "Brother Xian, don't sell Guanzi, if it's really good, you can ask someone to take a look." ”

Seeing that Yang Rui, the "turtle", really didn't know Mr. Snow Village, Zhong Guanguan was only impressed, the Mr. Snow Village he was talking about was actually Xu Shou, and Mr. Xu was Mr. Xu Shou's youngest son Xu Huafeng, as for the eldest son Xu Jianyin, who had an accident in the Hubei Gun Factory as early as last year.

After the two of them summed up, Zhong Guanguan came forward to consult Mr. Xu Huafeng, who had taken care of them when they opened a phosphorus factory the year before last, and he now opened a soap factory in Shanghai, and asked him to help him without any problem; Second, according to what Yang Rui said, the newspaper recruited chemical engineers, published the recruitment notice in the main Chinese and English newspapers, and wrote a notice according to the common model of later generations, Yun He has good welfare, preferential treatment, and no restrictions on men and women, etc., and the notice also requires applicants to mail their resumes to the Science and Technology Museum, and asks not to visit, do not disturb, and also requires to recruit a bookkeeper, requiring to understand Western accounting.
