Liu Mingqi had already made plans in his mind to go to Gumen Pass this time.
"These hidden reefs in the rivers are troublesome even if you say they are troublesome, and not troublesome even if you say they are not.
For thousands of years, countless smart people have been trapped by various instruments and methods, but they have been unable to solve such a large-scale and iron-hard reef area.
But for a young man with a Ph.D. in physics and chemistry, is this a problem?
No problem at all!
Just blow it up with explosives!
Even if the explosives are far from meeting the standards of the 21st century, the boy can still use them if he makes explosives equivalent to those of the 19th century.
"To be great, use quantity to determine the advantage. If a hundred kilograms doesn't work, I will use a thousand kilograms, or even a ton. I will blow up these reefs."
To be more precise, Liu Mingqi did not plan to use primitive explosives such as black powder. It was too much and the explosion power was extremely small. ¡ª¡ªWu Yu and Wu Yeshuang had used gunpowder to burn them before, but the result was obviously useless.
He was not going to use nitroglycerin explosives, even though he had a lot of glycerin on hand.
Because nitroglycerin is extremely unstable, even simple vibrations can cause it to explode.
Without specific industrial production standards, there is no way to produce a large amount of qualified and stable nitroglycerin for industrial use.
Liu Mingqi doesn¡¯t want to carry around a powder keg that¡¯s ready to explode at any time.
Even if you add passivation, coking, etc., it is not very reliable and there are always hidden dangers in manufacturing.
Especially since these explosives are to be used on underwater reefs, where the environment is extremely dangerous, it would be better to cherish the lives of the workers more.
He chose trinitrophenol explosive, also known as picric acid explosive, whose chemical name is tnp.
And its big brother is the well-known trinitrotoluene explosive, commonly known as tnt.
? tnt was still widely used until World War II, including the battles in which our country rushed to the rescue and fought with the coalition forces. It was the main force.
But the production method and process of TNT is much more complicated than that of picric acid explosives, and the performance of picric acid explosives is actually not much worse than that of TNT.
The famous c4, have you heard of it?
The power of picric acid explosive is no less powerful than it!
So Liu Mingqi chose picric acid dynamite.
Picric acid, a terrifyingly powerful explosive, was actually used to make yellow dye when it was produced, and people happily used it for decades.
Until one time, in a dye shop in the suburbs of Paris, a pipe of picric acid could not be opened because the iron barrel was rusty. The man hit the iron barrel hard with a hammer, and suddenly a violent explosion occurred. The fuel store was reduced to ruins, with numerous casualties. .
Since then, picric acid has been brought to the attention of the military, resulting in the production of powerful explosives, mainly used in artillery shells.
When Japan fought against the Beiyang Fleet, it relied on picric acid shells to defeat the Beiyang Navy, which was known as the number one in Asia. A few years later, when they fought the Russo-Japanese War, Togo Heihachiro also relied on picric acid shells and explosives, plus pigs to kill people. , defeated Tsarist Russia abruptly and won the war.
" Such a powerful explosive is not complicated to make, and the production process is not dangerous. Otherwise, it would be impossible to produce a large amount of yellow dye.
When the Englishman Wolfe treated phenol with concentrated sulfuric acid and concentrated nitric acid, he obtained this yellow solid - trinitrophenol.
Liu Mingqi can clearly understand the equations and chemical reaction processes with her eyes closed.
However, refining concentrated sulfuric acid and concentrated nitric acid is also a very labor-intensive process.
Fortunately, the boy is not using it for industrial purposes. It does not require a large amount and can be completed in the laboratory.
He has done at least a dozen methods of refining concentrated sulfuric acid and concentrated nitric acid, and he could still do it in such a simple environment in ancient times.
In fact, another advantage of picric acid explosive is that it is not soluble in water and can explode in water. You only need to use a detonator to detonate it.
Isn¡¯t this kind of explosive just suitable for the reefs in Guimenguan?
¡¡
While thinking about it here, Liu Mingqi saw the third housekeeper Zeng Duoyi running over.
Among the three housekeepers in the mansion, Zeng Duoyi is responsible for various purchases.
Liu Mingqi¡¯s eyes lit up, ¡°Old Zeng, come on, come on, I just have a bunch of things for you to buy, hurry up and buy them for me, I need them urgently, you knowIn the Kang Dynasty, gunpowder already existed, but most of it was used to make fireworks and firecrackers, or more signal bombs.
Its biggest effect is to rely on the heat of sudden combustion, without considering any explosive effects at all.
Liu Mingqi once went to see the gunpowder ratio of this era. It didn't even reach the ratio of 7 to 2 to 1, and there were more than just those three kinds of raw materials. Many things were added, which actually affected the power of the gunpowder.
The young man gave it a try first, "My method is different from yours. Let me prepare for ten days. I guarantee there will be a surprise when I arrive."
If this were said to another person, Wu Yeshuang would think that he was being mysterious.
But when it came to Prince Yu, who had recently become enlightened and repeatedly created novel gadgets, Wu Yeshuang felt a little more curious and expectant.
Wu Yeshuang nodded and said, "Don't be too anxious. It's not October yet. It should be December when the water level is at its lowest, making it easier to conduct on-site inspections."
"On-the-spot investigation?" Liu Mingqi looked at her and said, "Have you also visited the reefs at Guimenguan?"
"Nonsense, how about taking measures?" Wu Yeshuang said, "Thousands of us go there every time."
"How did you go? Aren't you afraid that the ship would be destroyed and people would die?"
"December has entered the dry season, and the water is not so fast. We use iron chains to anchor the boat in the middle of the Grand Canal, then use the boat to reach the nearby area, and then swim across." Wu Yeshuang said with a strange look on his face "I remember you almost drowned. How about it? You're not afraid of swimming now, are you?"
"How is this possible?" Liu Mingqi immediately denied it.
His admiration for this female minister increased even more.
She is not only good at leading these people to work on water conservancy projects, but she also personally works on it. Such an official who is deeply involved in the front line can most easily accomplish something.
Not to mention that Wu Yeshuang is still a woman.
No wonder so many people inside and outside the imperial court felt resentful for Wu Yeshuang.
"That's good." Wu Yeshuang nodded, "Actually, His Majesty asked you to go over now, just to check the situation first. Don't underestimate the door of hell."
"How could I be so arrogant?" The young man said, "Don't worry, I know what's appropriate."
"good."
Wu Yeshuang stood up and said, "I hope you can still create miracles. If the Gate of Hell can disappear, the Grand Canal will definitely benefit thousands of people, and you, Prince Yu, will be famous throughout the ages, no less than your sacrifice of life for righteousness."
Liu Mingqi suddenly smiled.
It seems that I have a good reputation.
Even this female minister, who was born in the Mohist family and had no impression of Confucianism, admired it.
Mencius, you are indeed the light of China!
It¡¯s really thanks to you, boy!
¡¡
Note: The reason why I write picric acid instead of tnt is because I searched for a long time and couldn¡¯t find any information about the formula. The laboratory method is too esoteric and cannot be explained in an easy-to-understand manner, let alone practical. Mass manufacturing.
If there are any shortcomings in this aspect, please correct me, so as to improve the scholar's knowledge breadth. Thank you. (Remember the website address: www.hlnovel.com - Didn't finish reading?
