The preparation process is not complicated and mainly consists of nitrification and refining. However, one thing that needs attention is the toxicity of trinitrotoluene.
The King of Explosives is moderately toxic and can enter the human body through the respiratory system, digestive system and skin, causing toxic reactions in skin, liver, stomach, blood, eyes and other body organs. In severe cases, it can cause death.
In order to develop this king of explosives, which was born in 1863, Yu Hua specially made two sets of chemical protective suits by hand, specifically to protect himself and Xu Rui's safety. He did not want to end up sick after the research mission.
At this time, the research and development progress on the King of Explosives in the laboratory is nearing completion.
Yu Hua was wearing a chemical protective suit and a gas mask that looked like a pig's nose. There was a needle-like colorless crystal on the operating table. This was the king of high-purity explosives. Next to him was his old buddy, Lei.
Mercury acid.
The extremely stable king of explosives and the mercury fulminate used for detonation are an inseparable combination. Although he was developing trinitrotoluene, Yu Hua still managed to master the mercury fulminate.
Holding a pen in his right hand and a notebook in his left hand, Yu Hua silently recorded the last part of the experiment.
The notebook records the detailed refining steps of the king of explosives, the three nitrification steps, the raw material extraction process, etc., as well as the mercury fulminate production process.
Toluene, the core raw material of the king of explosives, mainly comes from petroleum. During the Anti-Japanese War, the Eighth Route Army already had the Yanchang Oilfield with a daily output of about 1.5 tons.
1.5 tons may not be much, but it definitely meets the production needs of the King of Explosives.
In addition, for future production expansion needs, Yu Hua also thoughtfully sent the coordinates of a heavyweight underground oil production area - Yumen Oilfield in this notebook.
Exact coordinates: 15 meters north of Yumen Laojun Temple.
Yumen Oilfield was founded in 1939 and was the only large-scale oil field in production during the Anti-Japanese War. Its oil production accounted for 90% of the total oil production during the Anti-Japanese War, reaching 250,000 tons.
The Eighth Route Army did not lack industrial blood and raw materials. What it lacked was only industrial foundation and technology. The industrial foundation Yu Hua could not satisfy, but the technology, if not enough, at least had it.
Next to him stood Xu Rui, also wearing chemical protective clothing, holding a small book in his hand and a pen in his right hand to record what he had learned today.
A good memory is worse than a bad pen.
After these days of study and experimentation, Xu Rui already has very rich experience in making gunpowder and has mastered the production processes of three gunpowder technologies. Now, he is learning the principles and basic knowledge of chemical reactions.
"Remember, the third nitrification is the most important. It is a two-phase reaction, and the reaction formula is..." Yu Hua explained the basic chemical principles and nitrification reaction formula to Xu Rui while recording the detailed experimental steps in the last paragraph.
Xu Rui nodded repeatedly.
After about a few minutes, Yu Hua finished explaining the basic principles of chemistry and writing the experimental record. He put down the pen, took a look at the finished product, and said to Xu Rui: "Rui Zi, organize the finished product and keep it properly. How many experimental materials are left?"
"Sir, the experimental materials are basically gone. The remaining sulfuric acid and nitric acid can still be used to prepare a single base drug. If necessary, I will buy it immediately." After hearing this, Xu Rui replied as he gave the information like a treasure trove.
"No, you can dispose of the remaining materials later. How much money do we have left now?" Yu Hua shook his head slightly and changed the topic to ask about funds.
The completion of the research and development of trinitrotoluene gunpowder means that the entire gunpowder research and development plan has come to an end, and there is no need to waste money on purchasing chemical experiment materials.
Single-base powder, double-base powder and explosives, including three gunpowder technologies with seven different styles of gunpowder formulas, are suitable for almost all types of weapons, including pistol bullets, rifle bullets, machine gun bullets, mortar shells, and large-caliber artillery shells.
Primers, grenades, mines, explosive bags...
The gunpowder research and development plan has come to an end, and the next thing Yu Hua has to do is mail it to Lin Wan.
Xu Rui quickly gave the amount of remaining funds and responded: "There is about a thousand oceans left. During this period, I spent a lot of money buying guns and chemical materials. I will let Xiaoxue remember the detailed accounts and expenditures."
The entire chemical laboratory cost one thousand two hundred and fifty yuan, plus the purchase of guns and subsequent purchases of expensive chemical experiment materials, such as centralizers and various other expenses, the remaining funds were only
About a thousand oceans.
In this case, Yu Hua got 300 yuan in legal currency bonus from the school and went to the black market to exchange it for a thousand yuan.
There are only one thousand.
Yu Hua pondered this number silently. A thousand oceans seemed like a lot, enough to last Yu Hua and Xu Rui brother and sister for many years, but if placed on the next project, it would not be enough.
For a seven-tower device to produce sulfuric acid, the initial R&D investment would be at least 3,000 oceans, and 1,000 oceans is far from enough.
It’s time to attract investment.
When Yu Hua was facing a dilemma, the faces of the wealthy Zhou Yuan and the young rich woman Fang Yu already appeared in his mind, as well as Lin Wan, who had already become the representative of the Eighth Route Army in his mind. With his current connections and popularity, it shouldn't be difficult to borrow some money.
…
It has to be said that Yu Hua's technology research and development process is actually unhealthy. He only reaches the stage of producing results and lacks the most critical product sales link. He is unable to transform scientific research results into products, obtain profits, and then invest funds in research and development.
, forming a healthy technology research and development ecological chain.
Without a healthy ecological chain, it is natural to be unable to obtain sufficient funds.
However, before the Japanese army was about to launch a war and World War II was approaching, Yu Hua was unable to open a company in the country and establish an industry-research ecological chain.
Well, even if he opened a company, Yu Hua not only had to face the Japanese, but also the corrupt officials of the Republic of China.
And this resulted in a situation where Yu Hua had technology but no funds.
"I understand, you go ahead." After Yu Hua finished thinking, he picked up the notebook that recorded the three gunpowder techniques, turned and walked towards the lounge.
Xu Rui suddenly asked: "Sir, what should I do with the laboratory? Does it need to be demolished?"
"The laboratory... will be kept for now. These instruments and equipment are still useful." After hearing this, Yu Hua stopped, looked back at the small chemical laboratory that had been with him for dozens of days and nights, pondered for a while, and said.
"Okay." After receiving the instruction, Xu Rui nodded.
Yu Hua came to the lounge, changed into plain clothes, carried a backpack containing the handwritten versions of "Gunpowder Technology" and "The Barefoot Doctor's Manual" with a pen, left the laboratory, and headed to the Dongcheng District Post Office.
It is Yu Hua's principle to change places once and for all, and not to send things twice to the same post office.
After a month of meticulous craftsmanship and careful review, it was confirmed that there were no more quotations or atmosphere of the times. The pure handwritten version of "The Barefoot Doctor's Manual", which was Yu Hua's painstaking efforts, was finally released, with a total word count of 2.6 million words.
Writing 2.6 million words by hand in a month is what Yu Hua can do. This is an epic book no less than "Mechanical Drawing". Yu Hua is not going to submit it to an academic journal, but is going to submit it through Lin Wan.
Printed for Xinhua News Agency.
It was so important...so important that Yu Hua didn't even want to copy it by hand a second time.
Damn it, one copy of this thing would cost more than two million words. In order to ensure that the original manuscript could be printed, Yu Hua did not hesitate to rely on the connections he had accumulated with the Eighth Route Army.
Yu Hua believes that with the help of red secret deciphering information and mechanical drawing, he should have accumulated a considerable degree of popularity on the Eighth Route. This is a kind of friendship and a kind of popularity.
Other newspapers and magazines may not print "The Barefoot Doctor's Handbook", but Xinhua News Agency will definitely!
The sun is scorching in the sky and the weather is hot.
After exiting the narrow and quiet alley, we came to the bustling Xishiku Street. There were many pedestrians on the street, and there were constant shouts. Yu Hua, wearing a gray gown, walked slowly and slowly on the right side of the street, with a straight back and a steady and steady pace.
powerful.
Seeing Yu Hua with such a demeanor, many pedestrians subconsciously moved out of the way, feeling a sense of respect in their hearts.
There is poetry and calligraphy in his belly, and Yu Hua already has a faint scholar's temperament in him.
Elegant and confident.
Even if he is wearing a cheap gown, his aura is indelible.
There are two post offices in Dongcheng District, one in the north and one in the south. The closest one is Dongcheng North Bureau. Go south along Xishiku Street, pass by Xishiku Church, and come to the fork in the road. Yu Hua turns left toward Jingshan Park.
go.
Jingshan is the Meishan where Emperor Zhu Youjian and Chongzhen were hanged in the late Ming Dynasty.
Pass through Jingshan Front Street between Jingshan Park and the Forbidden City, and walk a while further to reach Dongcheng North Bureau.
As we arrived near Jingshan, we were greeted by a long and rich historical atmosphere. The stretching palaces came into view. The majestic and spectacular Forbidden City was filled with the aura of supreme imperial power.
Looking at the Forbidden City in the distance in 1937, the most magnificent and tallest building in Peiping City, Yu Hua couldn't help but stop and remain silent.
This is the second time he has seen the Forbidden City in person.
The first time was the 70th anniversary military parade in 2019. At that time, the Forbidden City was majestic and spectacular, with bright red everywhere, exuding an indescribable surging atmosphere, like a man who had just grown up, full of vigor.
Although the current Forbidden City has not changed and is still grand and tall, it has an air of dilapidation.
One is the scorching sun, and the other is the pearl of a grain of rice. They are the same, but they cannot be compared.
"Not long after, I will be a slave to the country's subjugation..." Yu Hua looked at the Forbidden City quietly for a long time and slowly said this sentence.
"Yu Hua?" At this moment, a magnetic male voice came, not in Chinese, but in German.
When Yu Hua heard the shouting, he was a little confused. When he came back to his senses, he turned around and saw that it was John Davis, Mr. Physics, wearing a suit and holding a briefcase in his hand. There was another unknown person standing next to him.
foreigners.
"Hello, Mr. Davis, why are you here?" Yu Hua was a little confused when he saw Davis, and hurriedly stepped forward to say hello, speaking in a fluent and standard Berlin accent.
Davis was so happy when he heard this pleasant Berlin accent German, he smiled and joked: "That's exactly what I want to ask, why are you here? You know, the day after tomorrow is everything."
The city's joint entrance examination, and as the number one in the school, you are not in school."
It has to be said that the reason why Davis allowed Yu Hua to study on his own was inseparable from his fluent and standard Berlin accent German.
This is the first time in all the years he has been in China that he can communicate without any barriers.
"Sorry, Mr. Davis, I will go back to school immediately after I finish my work." Yu Hua responded.
"Okay, Yu Hua, I'm just kidding."
Davis's smile did not fade and he said to Yu Hua: "I'm here to meet a friend. Let me introduce you. This is John Rabe, the representative of Siemens in China. He is a good friend of mine. Rabe, this is what I have always said.
The student I mentioned to you, Yu Hua. I asked him to give him a German name, but he refused. Hahaha, he is the most talented and smartest student I have ever seen. There is no one. If I want to say how smart he is specifically
, I think he is no less than Einstein in his youth."
who?
Regarding the words of Physics Mr. Davis, Yu Hua was stunned on the spot, a little unable to react. The reason was not from his praise, but from the person he introduced...
John Rabe!
This is an unknown foreign name, but his name is worth remembering by every Chinese, so Yu Hua memorized this name.
His eyes involuntarily fell on the German wearing glasses next to him. After looking at him, a hint of respect involuntarily appeared in his eyes.
