Chapter 870: Lao Zhang's Organic Chemistry

The two chatted for a while, and then the topic turned to pediatrics, saying that pediatric convulsions are also a common symptom of Jiaozhi, and Zhang Daochang thanked Shi Wei and Su You for the pearl powder sent to the Tianshi Mansion in Bianjing City.

The pearl calms the heart, nourishes the yin and extinguishes the wind, clears away the heat and falls phlegm, removes the eyes, detoxifies and builds muscles. Treatment of palpitations, apprehension, epilepsy, convulsions, heat and thirst, laryngeal paralysis, scrofula, and eye barriers.

Shi Wei said with a smile: "That medicine didn't cost a penny, but it was ground down from the inner layer of the pearl shell after Brother Xiaoyou saw me hammering pearls." I tried it with the same effect, and in the future, all the patients of my Da Song Dynasty will be able to use the pearl medicine. ”

Zhang Daochang once again bowed: "This is another great merit, and Jiaozhi is really a blessed place for accumulating Taoist merits...... Immeasurable Heavenly Master, the poor path has fallen into the trap again. ”

Su You seized the opportunity to speak, and also made a mockery to Daoist Zhang: "Don't talk about dibutyl sulfur glue, only the Taoist chief has studied the way of the rest of the glue paint, and the invention of various paints, rubber materials, and adhesives is amazing." ”

"It is the first kind of plastic film in my Great Song Dynasty, which can make the seedlings of farmers all over the world survive the cold of spring, which is immeasurable."

This is an unbelievable thing, even if Su You's brain is too big, he can't imagine that the scientists of the Song Dynasty can go so far to the technology of plastic film after being clicked on the golden finger of organic materials by themselves.

The method is like this, after the invention of the retort furnace, the Song people used it to dry distill coal, sulfur, cinnabar, and all kinds of alum crystals.

And Zhang Daochang is very simple and uses it to distill wood.

At the same time as preparing charcoal, dry distillation gas is also introduced, and chemicals such as wood essence and wood acetic acid are obtained.

Wood essence is methanol, which is neutralized with lime and then distilled to produce another super organic solvent - lignone.

The discovery of xylone is acetone, and its discovery has directly raised the pigment industry, spice industry, smokeless explosives industry, paint industry, viscose, and Celuro production processes in Shuzhong to a huge level.

In the case of 600 to 700 degrees, wood essence can be directly oxidized with air and water vapor through catalytic nets such as silver and copper to form another substance, which can be absorbed with water to become a miraculous solution - xyloghyde.

Xyloghyde is formaldehyde, which is mixed with a specific concentration of aqueous solution of wood alcohol, which is a super preservative, and Tianshifu found that it has a special effect on killing microorganisms in the water, in addition to treating fish diseases, it can also make specimens.

It's something that everyone is very familiar with in later generations - formalin.

When Zhang Daoren stirred gelatinization with konjac essence powder, xyloghyde solution, caustic soda solution, glycerin, and lubricating oil, he found that they had become a very peculiar gel.

Zhang Daoren poured it on the glass plate and shook it to extend the stream, and then let them dry under natural conditions, and when it was lifted from the glass plate again, the gel turned into a magical thing - plastic film!

This is the second kind of plastic invented by the Great Song Dynasty since Sailuluo, and it is a plastic that has not been instructed by Su You, and has been explored by the Great Song people themselves!

The process is mature, the cost is low, and the output is huge!

The biggest use of this thing is as a bullet shell interlayer for paper shell bullets, and the moisture-proof effect is so good that it is against the sky!

It is also used as a coating to isolate the mercury from the copper cap!

With the two great inventions of vulcanized dibutine gum and konjac gum, Zhang Daoshi became an academician of the Academy of Chemical Engineering of the Royal Institute of Technology.

Su You said with a smile: "There are still many things now, I built a sanatorium for the Taoist chief in Halong Bay, during this time, the Taoist will recuperate well, there are many toxic substances in the chemical industry that are harmful to the body, by the way, let Wei'er check your body, and when you are busy for a while, I will accompany the Taoist to visit." ”

"I'll draw a few more drawings in a while, send a few pieces of glass to the Taoist, and dive in Halong Bay in the summer to catch lobsters and sea cucumbers and scallops, it'......s so beautiful to think about."

Saying goodbye to Daoist and Shi Wei, Su You came to the capital hall humming a song, and Yao Bu came forward: "Shaobao, there is a big cannibal, I've been waiting for you for two days." ”

Su You asked, "Big cannibal?" What's the matter? ”

Chao Buzhi smiled secretly: "It's nothing, you didn't say it, if someone is interested in the fish sauce you invented, let him come to you?" What is it said to promote...... Food culture? ”

Su You held his head with his hand: "In fact, the taste of low-salt and fast-fermented fish sauce is not good, and it takes two or three years for a really good fish sauce to become like a good soy sauce...... Forget it, call in, and I'll see what the big cannibal who likes fish sauce looks like......"

After a while, Chao Buzhi brought Pu Shan in.

Only then did Pu Shan know who was going to see him, and she was so frightened that she stammered: "Honor...... Dear ......"

Without waiting for him to finish, Su You asked, "Why are you interested in fish sauce?" ”

Pu Shan was very honest: "Because of other goods, villain...... The villain really can't afford it...... Mead and the like, but not novel enough......"

Chao Buzhi couldn't help but turn his head and snicker.

"That's it......" Su You felt that he was happy in vain, and hesitated: "How much money do you have?" ”

Pu Shan said: "Yesterday I showed the villager the house, and the villager gave me a silver coin, and then ...... I told him that there are many discounts for buying a house now, and the fellow was happy and ...... Gave one. ”

Su You sympathized with Pu Shan: "Just your two silver coins, is it enough for the return journey?" ”

Pu Shan said: "I can use it as a clerk for the passing ships, but I don't need to pay for the journey, and I have a few silver coins of wages that have not been paid. My lord, how much is your fish sauce? ”

Su You thought about it very seriously, two silver coins are two pieces, Pushan's fellow is very generous, the small sea fish is worthless in Meizhou, the rest is the salt water left over from the pickled fish, and one hundred pounds is enough to earn a black heart, so he said: "One silver coin, I can give you ten catties of fish sauce." This thing can last for a year to a year and a half, but how do you ship it back? ”

Pu Shan said: "I don't dare to work anymore, just tell me where to pick up the goods." ”

Su You picked up the pen and wrote a note and handed it to Pu Shan: "In this case, I will write you a note, and you can go to Sitong Firm to withdraw it." ”

Pu Shan saluted again and again, and retreated while saluting: "Thank you, thank you, my lord." ”

Seeing that he was about to leave the capital hall, Su You shouted: "Wait! ”

Pu Shan said: "I don't know what else the adults have to say? ”

Su You spread his hands: "Where's the money?" You haven't given a deposit yet! ”

Only then did Pu Shan react, took out two silver coins from his arms, and respectfully put them back on the table: "Thank you, for your busy schedule." The villain said goodbye. ”

Pu Shan left, Su You picked up a silver coin and blew it on the edge of his mouth, put it in front of his ear and listened to the voice with a look of a wealth fan: "No blame, two jars of fish sauce can earn at least one silver coin, big profit......"

Chao Buzhi smiled and said, "Teacher, aren't you really teasing that Pu Shan?" ”

Su You said: "No, I am doing business with him seriously, this person is good, it reminds me of my own time." ”

Chao Buzhi said: "But how did I hear that the teacher did all the business without capital back then? ”

Su You nodded his head: "My capital is here, how can it be said that it is a business without capital?" ”

With a blood pressure monitor, you should be able to refer to the door of your brain when you say that you are thinking about problems.

Pu Shan's affair was just a small episode, and Su You himself quickly forgot about it.

There are still many things to worry about next, more than 30,000 migrants in Meizhou are in urgent need of resettlement, and the support they need is also massive.

Fortunately, this trade will make a little scary, so he generously allocated 300,000 yuan of materials to Shen Kuo.

At the same time, Su Youxing Wen Meizhou, Yunzhou, Yezhou, Jiaozhou, Ning Navy.

In various ports, the construction of forts began.

And he called Zhang Qi, Shi Wei and Pingzhengsheng and began to inspect Jiaozhi County.

In the Great Song Dynasty system, all the transit envoys were transferred to a tax for the state, and they were also divided into patrol departments and supervised officials.

In a year, you have to spend half of the year in the jurisdiction, otherwise you will be neglecting the government.

The first is the Yezhou Industrial Center.

The first thing Su You visited was the most advanced iron-making blast furnace in the Great Song Dynasty.

The development of the metallurgical industry to the present, from the time with Shi Fu, the "earth blast furnace" behind the Su family house in Kelongli, if it is regarded as the first generation, then the second generation in the second forest department, the third generation in Dukou, the fourth generation in the Sansi case, the fifth generation in Zhengzhou and Shangzhou, and today, it is the sixth generation.

Before Su You's participation in the transformation of the Great Song Iron and Steel Industry, a smelting field in the Great Song Dynasty had an annual output of about 40,000 catties of refined iron. "It's already a big eunuch.

According to the archives that Su You saw in the Sansi, in the Renzong Dynasty, the iron class of the Great Song Dynasty in one year, that is, the iron output handed over to the state treasury by the metro metallurgy, was about five million catties, and most of it was concentrated in the north.
