Chapter 1244 The Fair Land (First update, please subscribe)
No matter what the outside world thinks of Emperor Zhu Da, what is certain is that it was he who single-handedly created this country.
This is something that no one can deny. Before him, the Pampas was just a grassland, and even the whole of South America was nothing more than the source of European raw materials - the Pampas was used for European cattle grazing.
The Amazon is the forest area of Europe, Peru is the silver mine of Europe, Chile is the copper mine of Europe, and Brazil is their sugar cane, coffee, and spice plantations...
In short, South America at that time had neither industry nor the dawn of modernization. It seemed that the dawn of the industrial revolution had never shined on this fertile land.
But the appearance of Emperor Zhu Da changed everything here. He not only allowed modern civilization to take root in this land and science to shine on this land, but more importantly, this land that once belonged to white Europeans became
With the fertile soil of China, tens of millions of Chinese people blossomed, bore fruit, and thrived in this fertile new continent of South America.
This is the most beautiful era and the most creative era. For every Ming Dynasty 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 and talents,
You can get huge wealth.
This land will neither be stingy to those who work hard nor favor those who work wisely. It is fair to all those who work hard.
Tang Haodong is a chemistry teacher at Luoyang High School. He graduated from Nanhua Normal University. He came to Luoyang five years ago. It is the provincial capital of Henan Province - well, this Henan is located south of the Amazon, which is the state of Pará, and Luoyang is
Para City, a city that prospered due to the wild rubber trade.
Since the imperial rule, the rainforest has been reclaimed into tropical plantations. The influx of a large number of Chinese immigrants has further prospered the city, and at the same time changed the city's demographic structure-Chinese have become the mainstream of the city.
However, all 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 to engage in research.
In the Ming Dynasty, everyone has the opportunity to become an inventor and to change their own destiny through their own intelligence. Of course, inventors are also talents highly respected by society.
They invent and innovate, they change mankind, and of course, more importantly, they have wealth.
Inventors... were synonymous with status, wealth and reputation in the Ming Dynasty.
The bright moonlight is reflected by the window of the school's chemistry laboratory, but the lights are still on in the laboratory. The light of the electric lamp is reflected through the glass window into the room. Tang Haodong, who is wearing white clothes in the room, moves around from time to time.
In front of you is a pile of glassware.
"... Bayer's first method of synthesizing indigo could only stay in the laboratory stage because of its long route, low yield, high cost, and poor quality. So it subsequently studied a second method.
Synthetic route, but it 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 are from natural sources, so it makes no sense to cost more than natural indigo..."
Tang Haodong was not talking to himself, but was explaining his idea of synthesizing indigo to the students around him who were interested in chemistry and had excellent chemistry scores. While Tang Haodong was explaining, his students were recording in their experiment notebooks.
Follow the testing process.
This is a high school laboratory, and it is also a place of invention. Last year, when the news that Bayer won the 1886 "Shengde Emperor's Chemistry Prize" for proposing the structural formula of indigo reached this remote town, as a high school teacher
Tang Haodong began 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 destroying their jobs. Plantations, you can grow other things without bluegrass.
.
Although Luoyang is remote, the experimental equipment in the high school chemistry laboratory is quite complete, many of which were donated by local wealthy businessmen. This also opened the door for Tang Haodong's invention. If the bluegrass plantation owners outside the city
, I don’t know how I would feel if I learned that the equipment they donated to build was actually used for an invention that destroyed their jobs.
But they can’t help but think about it. After all, it’s 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 thirty years, cheap artificial dyes have
Synthetic dyes replace natural dyes.
The indigo that Tang Haodong wants to synthesize now is the most widely used dye. Not only does blue dye use a large amount, but it is also the basic color in dyes. The indigo used around the world is extracted from various indigo grasses, and its price has always been high.
Not too high.
Just like this, in the past few decades, British, French and German chemists have been trying to synthesize indigo. It was not until 1870 that Bayer obtained indigo by reacting indigo with phosphorus trichloride, phosphorus and acetyl chloride. Although he
Later, a method was invented, but because the cost was too high and the yield was low, it still could not replace natural indigo.
The synthesis method Tang Haodong is currently experimenting with is a method he invented three months ago. He took a new approach and bypassed isatin and instead used the condensation of indole phenol to synthesize indigo. How to prepare indole phenol through the condensation of aniline and chloroacetic acid
Phenylglycine ortho-carboxylic acid is obtained and then subjected to alkali melting treatment. The main problem of this process is the high cost of aniline and chloroacetic acid. Because aniline has a small content in coal chemical by-products, and now aniline dyes have begun to be used on a large scale.
The actual demand for aniline is very large, which further drives up the cost. Therefore, Tang Haodong has been studying new synthesis 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. He frowned. After the test failed, Tang Haodong checked the test report again. What exactly needs improvement?
Gu Huaxin, who was assisting the teacher in the experiment, noticed the teacher's frown and thought, and said.
"Teacher, in fact, the method you invented before has almost production value. I have calculated that its cost is 10% lower than 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. Let's find another path."
Perhaps I was a little upset, but when I ran the experiment again, I accidentally broke the thermometer during the reaction because I moved a little more violently.
"..."
Just when Tang Haodong frowned in frustration, he unexpectedly discovered that the reaction in the experimental dish had changed.
"this……"
"The teacher seems different from the past..."
The classmates stood nearby 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, mercury combined with sulfuric acid to form a mercury sulfate catalyst, which unexpectedly accelerated the reaction.
It was this accident that immediately opened up the entire process...
Looking at the indigo obtained through the reaction, Tang Haodong said with some excitement.
"We, we succeeded... we succeeded..."
