Chapter 1244 Fair place (first update, please subscribe)
No matter how the outside world evaluates Emperor Zhu, it is certain that he created this country single-handedly.

This is something that no one can deny. Before him, the Pampas prairie was just a piece of grassland, even the whole of South America, and it was nothing more than the source of raw materials in Europe—the Pampas prairie was used for European cattle, The Amazon is the forest area of ​​Europe, Peru is the silver mine of Europe, Chile is the copper mine of Europe, Brazil is their sugar cane, coffee, spice plantations...

In a word, there was neither industry nor the dawn of modernization in South America in that era. It seems that the dawn of the industrial revolution never shone on this fertile land.

But the appearance of Emperor Zhu changed everything here. He not only allowed modern civilization to take root in this land, but also allowed science to shine on this land. More importantly, this land that once belonged to white Europeans became With the fertile soil of China, tens of millions of Chinese sons and daughters blossomed, fruited and multiplied in this fertile new continent of South America.

This is the most beautiful era, and also the most creative era. For every Daming person, their soul has been recast. As long as they are willing to work, they can get rich rewards, as long as they are willing to use their intelligence, You can get huge wealth.

This land will neither be stingy with the laborers nor favor the wise ones.He is fair to all hardworking people.

Tang Haodong is a chemistry teacher at Luoyang Higher Middle School. He graduated from South China Normal University. He came to Luoyang five years ago. It is the provincial capital of Henan Province—well, this Henan is located in the south of the Amazon, which is Para State, and Luoyang is Pala City, a city that thrives on the wild rubber trade.

Since the rule of the empire, the rainforest has been reclaimed as tropical plantations, and the influx of Chinese immigrants has further prospered the city, but it has also changed the population structure of the city - Chinese have become the mainstream of the city.

However, all of this has nothing to do with Tang Haodong. His job is to teach and educate people. Of course, the school environment also allows him to have time for research.

In Daming, everyone has the opportunity to become an inventor, and has the opportunity to change their own destiny through their own ingenuity. Of course, inventors are also highly respected talents by society.

They invent and innovate, they change human beings, and of course, more importantly, they own wealth.

Inventors... are equal to status, wealth, and reputation in Ming Dynasty.

The bright moonlight was reflected by the window of the school's chemistry laboratory, but the lights were still on in the laboratory, and the light from the electric light was reflected into the room through the glass window. In the room, Tang Haodong, who was dressed in white, was walking around from time to time. In front of him was a pile of glassware.

"...Bayer's first method of synthesizing indigo was too long, the yield was very low, the cost was too high, and the quality was not good, so it could only stay in the laboratory stage, so it then studied the second method The synthetic route, however, has not been applied. The reason is that the synthetic route he proposed is very cumbersome and the cost is very high. Both indigo and alizarin come from natural sources, and it is meaningless if the cost exceeds natural indigo..."

Tang Haodong was not talking to himself, but was explaining his idea of ​​synthesizing indigo to the chemistry-loving and outstanding students around him.While Tang Haodong was explaining, his students recorded the experiment process in the experiment notebook.

This is a high school laboratory, which is also a place of invention. Last year, when the news that Bayer won the "Emperor Sidley Chemistry Award" in 1886 for proposing the structural formula of indigo reached this remote town, as a high school teacher Tang Haodong started research in this area.

Synthesizing indigo means wealth. There are bluegrass plantations outside the city. Indigo is also an important export commodity in Luoyang. However, this does not prevent him from smashing their jobs. Plantations, you can grow other things without bluegrass .

Although Luoyang is remote, the high school chemistry laboratory has a complete set of experimental equipment, many of which were donated by wealthy local businessmen.This also opened the door for Tang Haodong's invention. If those bluegrass plantation owners outside the city knew that the equipment they donated to add was actually used in an invention that ruined their jobs, I don't know how they would feel.

But they can’t help how much they feel. After all, it is only a matter of time before natural dyes are replaced. The reason is very simple. Since the British synthesized aniline violet in 1856, mankind has entered a period of great development in the chemical industry. In the past 30 years, cheap synthetic dyes Dyes, replacing natural dyes.

The indigo that Tang Haodong wants to synthesize now is the most widely used dye. Not only is the amount of blue dye used in a large amount, but it is also the basic color in the dye. The indigo used all over the world is extracted from various blue grasses, and the price has always been high. Not high enough.

And so it has been over the past few decades.British, French and German chemists were trying to synthesize indigo. It was not until 1870 that Bayer obtained indigo by reacting isatin with phosphorus trichloride, phosphorus and acetyl chloride.Although he later invented a method, it still cannot replace natural indigo because of its high cost and low yield.

The synthesis method that Tang Haodong is currently experimenting with is the method he invented three months ago. He found another way to bypass indigo and use indoxyl condensation to synthesize indigo.How to prepare indoxyl, through the condensation of aniline and chloroacetic acid to obtain phenylglycine o-carboxylic acid, and then carry out alkali fusion treatment.The main problem of this process is the high cost of aniline and chloroacetic acid.Because the content of aniline in the by-products of coal chemical industry is small, and now aniline dyes have begun to be applied on a large scale, the actual demand for aniline is very large, which further pushes up the cost.Therefore, now Tang Haodong has been researching new synthetic routes.In order to solve this problem, Tang Haodong tried to start with naphthalene, which has a high content in coal tar and is cheap.

But this synthesis path is very troublesome. Until now, the synthesis path has not been opened up, and his brows were frowned. After the test failed, Tang Haodong checked the test report again. What exactly needs to be improved?
Gu Huaxin, who was assisting the teacher in the experiment, noticed the teacher frowning and thinking, so he said.

"Teacher, in fact, the method you invented before almost has production value. I calculated that its cost is 10% lower than that of natural indigo."

"What if the plantation is reduced by 10%?"

Tang Haodong asked casually,

"At that time, this invention will have no meaning at all, so let's change the path."

Maybe it was a little upset, when the experiment was carried out again, the thermometer was accidentally broken during the reaction because the action was a little more violent.

"..."

Just when Tang Haodong frowned in annoyance, he unexpectedly discovered that the reaction in the experimental dish had changed.

"This……"

"Teacher seems to be different from the past..."

The students stood by and said.

"It should be that the mercury in the thermometer combines with sulfuric acid to speed up the reaction..."

Indeed, as Gu Huaxin said, the combination of mercury and sulfuric acid formed a mercury sulfate catalyst, which unexpectedly accelerated the reaction.

It was also this accident that immediately opened up the entire process...

Looking at the indigo obtained through the reaction, Tang Haodong said a little excitedly.

"We, we made it...we made it..."
