In general, for now, sodium sulfate and bitumen are of little use, crude phenol is somewhat useful, and refined phenol can be used for antiseptic. Cresol can be used to make lysu water or medicated soap, which is much stronger than alcohol for disinfection.

As for synthetic fibers, pharmaceuticals, fertilizers, etc., it's a bit too early to talk about it, and when Wang Wu grows to the age of fifty, he can make these products in the laboratory, and the Great Song Dynasty will dominate the world.

Moreover, the phenols, sodium sulfate and asphalt that Wang Wu made out are not very pure, except for the equipment reasons, the main reason is to forget the important step, dewaxing.

Petroleum and coal tar contain a lot of wax and paraffin. Fractionated gasoline, diesel, and kerosene are not intended for use in internal combustion engines, but can be ignited, and can be dewaxed without the process. But if you want to purify the remaining compounds, you can't do without this step.

How to dewax it? In fact, it is very simple, just use bone charcoal. If there is no bone charcoal, it is calcined with feldspar and then crushed into fine powder, commonly known as white clay. They are the carrier of adsorption wax, and after repeated adsorption of clay, the purification process is carried out, and the final purity can be improved a lot.

But this doesn't mean that Wang Wu and they are just doing nothing, chemistry is a bit like climbing a mountain, every new discovery will take you one step higher, and then you can see more scenery.

The credit for being able to make use of the residues that had nowhere to throw away before, and to make them all useful things, must not be small. So Wang Wu became the head of the chemical laboratory, and he also had the official military rank, captain!

This is already comparable to Wang Da's status, and the five snot bubbles of the beauty king are about to come out, and at the same time, it also makes the other little guys full of envy and jealousy, and there must be no hatred.

It is strictly forbidden to hate between brothers and sisters, and it is a sin to think about it, and once it is discovered, it will attract very severe punishment.

Another person who has been promoted is Gao Yu, who would not have been able to experiment with precision without his day-and-night efforts to blow glassware and his success.

Scientific research is often produced by researchers, but there are many unsung heroes behind them, and without the help of these people, any research is an extremely long process.

"Warrant Officer Gao, don't always do it alone, smart people will use all the resources available to them. The only thing you don't lack around you is people, go and find people who are talented in this industry and suitable for joining the Youth League, and let them do it for you. ”

Compared with new compounds, telescopes, snow goggles, gas lamps, and flat glass are the products that Hongtao needs more. Gao Yu alone blows it, and blowing his cheeks can't meet the demand.

Hong Tao doesn't plan to feed them everything like a nanny anymore, these children are older and should master more skills, such as dominating his subordinates.

"I also want to do those interesting experiments with them, Wang Wu said that burning glass is also one of the tests, whoever masters this technology can become the enemy of ten thousand people like officials." Gao Yu had just been promoted, and he was a little bold and made a request.

"Didn't they let you into the lab before?" This is the first time Hong Tao has heard of this.

“…… They said I wasn't very trustworthy and couldn't know the secrets. Gao Yu is already an adult, but he is controlled by a group of children all day long, his body does not dare to resist, and his heart is even more aggrieved.

"Wang Da didn't intercede for you?" Hong Tao still doesn't quite understand, it is said that Gao Yu is Wang Da's husband, even if he is not officially married, but this matter is decided by himself, and the children should not be suspicious.

“…… She said that her status is earned by herself, not nepotism, so let me figure it out by myself......" Speaking of this daughter-in-law who has never been through the door, Gao Yu is even more helpless.

"Hahahaha...... Be content, boy, you have married a good daughter-in-law. No, it's not right, it's the official's discerning eyes that found you a good daughter-in-law. Now you've earned your respect, warrant officer, boy, no less than them. In the Youth League and the Children's League, there is no old seniority, only ability, and you happen to have some ability. ”

Thinking about Wang Da's face and teaching Gao Yu a lesson, Hong Tao couldn't care about maintaining the demeanor of an elder, and covered his stomach with a smile. It was all self-inflicted, originally intended to be a game, but now it seems to be really fun.

Just when Hong Tao built the first food processing factory in the east of Huangzhou City, 2000 miles away Mizhi Village ushered in a huge camel team, just the consignment of goods is more than 30 camels, the leading white camel is inserted with a white flag, with a blooming flower embroidered with gold thread in the middle, it is the rice sac flower.

This flag has been well known to many walled fort defenders in the northwest, and every time it comes, it will bring a lot of benefits to everyone. It is not known where the caravan came from or to which family.

The only thing that is clear is that the leader of the caravan is surnamed Hua and is still a woman. She has a lot of energy, and wherever she goes, she has customs clearance documents for the first-level forbidden army on the state road.

The guards of the camel team are even more fierce, except for the Fan people, Yishui is a veteran of the forbidden army. Even if there are no customs clearance documents, it is not too difficult to clear the goods of smugglers with the friendship of these veterans.

The defenders of Mizhi Village were more familiar with this camel caravan, it often went in and out of Yanzhou City, and had a close personal relationship with Lord Shen through the passage of the Yanyan Road, and belonged to the kind that could enter the palace anytime and anywhere. As a businessman, there seem to be few border gates that can do this.

It wasn't the defenders who were even happier, at most they were taking some benefits, and it was the merchants of the nearby states and counties who were really cheering. Every time the camel caravan of the shopkeeper came back from the border, it would bring a large number of cattle, sheep, furs, horses, and camels. Except for horses and camels, the rest of the goods will be handled by local merchants nearby, and the price is also fair, and anyone who can get their hands on it is very profitable.

But it is not the merchant who is the happiest, but Shen Kuo himself. Fu Ji knew him, and probably knew his origin. As long as he is not a district official, as long as he is not looking good, what is there to be happy about as the number one military and political leader guarding the border gates?

To tell the truth, Fu Ji's appearance is really not outstanding, it must be for wealth, and there are shares of Shen Kuo in this smuggling camel team.

No, no one in this caravan has any shares, every time Fu Ji comes to Shen Shuaisi, the gift is just a box of paper and pencils, a few bottles of wine, never a big bag to carry in, what really makes Shen Kuo happy is actually the letter that still carries Fu Ji's body temperature.

It was a letter from the king of the horses, and there was not even the most basic greetings in it, but it was often some strange symbols and crooked characters, or some incomprehensible sentences, or simply a lot of hand-drawn pictures. Well, the content is still incomprehensible to ordinary people.

But Shen Kuo could understand it, whether it was mathematical formulas, physical phenomena or instrument drawings, he was fascinated. If it weren't for the heavy snow covering the mountains in winter, Shen Kuo would have sent a letter to Huangzhou every day, writing down his many doubts.

After waiting for about ten years, with the arrival of Wang Xu's letter, these doubts were basically solved. But the hate thing is that every time a problem is solved, more problems will be created, and there will always be no end to the questions.

"Has the rich lady ever brought a letter from a colt?" Mizhi Village is not as good as Yanzhou City, this is a front-line military village, there is no Shuai Si Mansion, and Shen Kuo also has to live in a military tent. When he saw Fu Ji, he didn't say a word about the tiring travel, let alone ask the purpose of the caravan's trip, but stared at Fu Ji's chest very indiscriminately.

"My family officials have written a lot of letters this time, and Lord Shen is probably busy." Fu Ji didn't think about it, this Shen Shuaisi is also a weirdo, as weird as a colt. Only this time the letter was not kicked in his arms, but in a leather bag.

"Shhh...... This is the contour map of Jinqing's clouds? It's weird...... Is it really 2,560 steps high here? ”

Since he got the leather bag, Shen Kuo no longer bothered with Fu Ji, he didn't give him tea, he lay on the handsome case and looked at the large piece of paper taken out of the bag, and from time to time he had to rummage through the boxes and cabinets to find information to check and compare, but he still didn't understand too much.

“…… Come on, it's not tea yet! Rich lady, have your officials taught how to look at this picture? ”

What if you don't figure it out? Write a letter to the horse to inquire again, it will take a month to come and go, and Shen Kuo really can't wait. At this time, he remembered that Fu Ji was still in the tent, and he was about to ask, and he remembered that he hadn't served tea to anyone yet, so he quickly made up for it, so he asked.
