Chapter 151 Expert help, sulfonamides
Yang Tianfeng was a little puzzled and said in confusion: "During the War of Resistance Against Japan, military and civilian supplies were scarce, and the country's attitude towards the industrial side of the rear was not like this, right?"
Qiu Yuchi smiled bitterly and said something, which made Yang Tianfeng frown.
Before the War of Resistance Against Japan, China's steel industry not only stagnated, but also regressed compared with the Qing Dynasty and Beiyang periods. When the war broke out, due to the shortage of steel, it simply gave up the production of mountain artillery and howitzer. The war made steel popular. The government not only did not actively introduce policies to support the steel industry, but immediately increased taxes, increasing from 1.28 yuan to 90 yuan a year.
On the other hand, the share of government bank loans to industries is even more unimaginable. It was only 3% in 1940s, and by 1% in 1943, most of the steel enterprises in the rear end went bankrupt or stopped production.
The big problem of the National Government, or Chairman Jiang, is that he does not believe in the wisdom and strength of his own people and lacks the spirit of self-reliance. He started by buying, bought, and then asked Uncle Sam. He did not pay much attention to the filling gaps and research breakthroughs made by his own scientific and technological workers, and lacked support and encouragement.
For example, chemist Hou Debang worked hard to study new alkali production methods and invented the "Hou's alkali production method" and a new process for co-producing soda ash and ammonium chloride fertilizers, but it was not taken seriously and failed to achieve industrial production. The Lidian Chemical Factory, which was established by Mr. Zhang Dayu, which was a lignite-deep dry distillation and gasoline, refined oil through hard work, but the government did not support it, and it was difficult for manpower, material resources, equipment and funds, and was finally forced to stop it.
In the late period of the War of Resistance Against Japan, 100% of China's gasoline, 95% of steel, 90% of medicines, and 80% of weapons and ammunition were all supplied by the United States and Britain. Relying entirely on foreign aid, the national industry suffered a heavy blow, which greatly disappointed many scientific and technological workers with the heart of "industrial service to the country" and even lost their jobs and had no livelihoods.
Now, the short-term industrial development prosperity is just forced, and I have not given up on "respecting foreign countries and fawning on foreign countries" from my heart. The government is always looking forward to the interference of the great powers, and the heavy losses in the Battle of Shanghai are largely due to this reason.
Yang Tianfeng pondered for a long time, shook his head with a wry smile, "It's better to do your own thing!"
"If you encounter difficulties, Yang is willing to help you." Yang Tianfeng stood up and raised his glass, and said enthusiastically: "Even if Yang is not caught in major events, you can hire experts to make you feel safe and confident. I am afraid that you will look down on this small place and dislike it!"
"General Yang is polite."
"Thank you, General Yang. If you lose your livelihood in the future, you will definitely come and ask General Yang for a job."
"General Yang said it was true and did not lose his true nature."
……………………
Everyone just thought Yang Tianfeng was joking, but they didn't know that Yang Tianfeng really hoped that more experts could stay. The military production in the base area had developed rapidly, but he had higher requirements and goals.
"Mr. Qiu." It was originally a farewell party, but Yang Tianfeng was really reluctant to let some experts go. He found an opportunity to whisper to Qiu Yuchi: "Can you please leave later and guide our copper clad steel plate production?"
Copper clad steel plate? This is definitely a very innovative word and a rare new technology in the world. Qiu Yuchi looked at Yang Tianfeng and thought for a while, and asked tentatively: "Gun shell? Is this feasible?"
"It's totally feasible." Yang Tianfeng nodded confidently and said, "We have made steel with extension and tensile properties close to copper, but it cannot completely replace copper, so--"
Qiu Yuchi's eyes lit up. As a metallurgical expert, he knew what huge impact this technology would have, what important role it played in the war of resistance, and it was also the first in the world.
"This not only requires smelting technology, but also mechanical experts." Qiu Yuchi's eyes bet on an expert who was joking with others not far away, and said, "General Yang, if that person can stay, the chance of success will be greatly increased!"
Yang Tianfeng understood it, but he had long noticed that mechanical expert, steel rolling mill, stamping machine, and other mechanical equipment he had always dreamed of.
If you impress him, there must be a way. Whether it is to continue to throw out professional information or hire him at a high salary, Yang Tianfeng decided to spare no effort.
…………………
In the war years, although I had some time or had a different mind, military and combat were always the theme.
Yang Tianfeng returned from Luyi, discussing with experts while trying his best to keep him, while paying attention to the battlefield and the result of the Anqing attack.
Sucheng, Kaifeng, if Anqing is added, the victory of the three tough battles will greatly shock the Japanese army that was defending the city. It is likely that the Japanese army must strengthen the forces of each city stationed, which will bring about a clear restraining effect.
The Japanese have fewer mobile troops, and the intensity and frequency of sweeping will be weakened, which will undoubtedly bring a relatively relaxed opportunity for the anti-Japanese armed forces, including the Third Column.
Thoughts flew, Yang Tianfeng looked at Zhao Yurou and Hao Jiaqi wearing white coats busy doing experiments. When he became focused, Zhao Yurou showed a different expression from usual, with her long hair tied up, a slight pursed mouth, long eyelashes, and slowly blinking eyes. She was really attractive.
"Hey, what are you looking at?" Zhao Yurou suddenly found that Yang Tianfeng did not seem to pay attention to the experiment, but kept his eyes on her, with a faint smile as if he was appreciating and admiring.
"Oh, I'm watching you do the experiment!" Yang Tianfeng said stubbornly.
Zhao Yurou rolled her eyes and said angrily: "Okay, then you think, what's wrong with our experiment? What's wrong with it?"
Yang Tianfeng laughed, got up and pretended to look at the test tube, flask and other experimental instruments for a while, coughed dryly, and said slowly under Zhao Yurou's white eyes: "Bailangduoxi, clinical research was conducted in 1934, and streptococcal pharyngitis and its complications suffered by the youngest son of US President Roosevelt in 1936, and it was only well known to the general public."
"We know this too." Hao Jiaqi pushed her glasses with her finger and said: "It is said that research believes that the dye chromogenic group azo group is an effective group that causes it to have antibacterial effects."
Zhao Yurou nodded and said, "Our idea is to synthesize a large number of azo dyes, and then find a way to test their antibacterial activity."
"This is said to be wrong, and it was a misleading intentionally spread by the Germans." Yang Tianfeng framed the two of them without hesitation. Looking at the puzzled eyes of the two, he took out two densely written papers from his pocket, shook them and said, "This is the information I just obtained and sorted out. Under the conditions where coal chemical industry has a certain foundation, it should be possible to perform experiments. If you can invite an expert in biological bacteria--"
"Bring it." Zhao Yurou reached out and snatched it, not wary of Yang Tianfeng being much more agile than her. She gave in and flashed her a little.
"Don't worry, be careful to flash your waist." Yang Tianfeng took advantage of the situation to hold Zhao Yurou's waist and smiled and stuffed the paper into her hand.
Zhao Yurou snorted, eager to read the information, so she stopped pursuing the advantage.
P-aminobenzenesulfonamide was first synthesized in 1908 by German chemist Paulgelmo during his dissertation research at the University of Vienna. At that time, it was only studied as an intermediate for synthetic dyes, and its pharmaceutical value has not yet been recognized.
In 1932, chemists Josefklarer and fritzmietzsch synthesized the derivative of para-aminobenzenesulfonamide. In the autumn of 1932, when pathologists and bacterologist Gerhard Domak studied the antibacterial effects of azo dyes using mice as an animal model, they discovered that the red azo dye, Bailangdomak had a strong effect on the treatment of hemolytic streptococci infections from thousands of candidate azo dyes. This discovery later won the 1939 Nobel Prize in Medicine.
In other words, after a big circle, people discovered this antibacterial drug from para-aminobenzenesulfonamide to dye "Bailangduoxi".
"The reason why this medicine is effective is not because they are dyes, but because they contain sulfonamides, which are not dyes at all." Yang Tianfeng sat very close to Zhao Yurou, and almost touched her hair and explained: "You can make aniline from coal tar, and the main raw materials are available. I think using the second one is more convenient and quick..."
Zhao Yurou and Hao Jiaqi's heads almost squeezed together, and they whispered, completely turning Yang Tianfeng aside.
"My dad is coming soon, he must be more professional." Hao Jiaqi said: "What if it comes to my opinion, it would be better to use this mixed urea method?"
"I think so too." Zhao Yurou nodded and agreed, "Then let's start!"
The two girls finished talking by themselves and realized that Yang Tianfeng, who was ignored, was rolling his eyes and unhappy.
"We are going to start working." With the direction of work, Zhao Yurou's mood also improved. She smiled on her face and pushed Yang Tianfeng, "You go, you're so busy, there are a lot of official duties to deal with, right?"
"I have called so many times to ask me to guide me, and now I'm going to leave quickly." Yang Tianfeng stood up reluctantly and muttered.
"You go to guide the coal chemical plant, and there are also difficulties there." Zhao Yurou pushed Yang Tianfeng's back, only thinking that he was walking slowly.
"Okay, okay." Yang Tianfeng shook his head helplessly and reminded him: "Sulphane is toxic. You two should take good care of the mask and fire-fighting equipment. You must be prepared. If you find a dry cough, loss of appetite, bad smell in your mouth, headache, dizziness, fatigue, and listlessness, and you want to sleep after work..."
"I know, don't it all write on the paper! Lao Jia, call Xiao Zhang and Xiao Wang, okay?" Zhao Yurou stood at the door and smiled at Yang Tianfeng, reached out and closed the door.
