*(Don't believe what is covered in this chapter...) Don't believe it! It's all fake! )

......

"Your Highness, what else do you command?"

Yang Wenguang joked, which Cheng thought Tang Yi was not polite at all:

"Add ice."

Gotcha, add ice.

Yang Wenguang hugged the ice bucket and began to add ice.

At this time, General Yang was also curious, what is it? Let the Tang madman be so focused, he didn't even raise his head. Moreover, listening to his tone, he obviously didn't notice that it was himself and Jia Xianggong who came in.

Take a good look at the things on the stone platform, well, it's really nothing special, it's just a big tank with half a tank of cold water in it.

The reason why it is cold water is because there are still ice cubes in the water that have not yet melted.

In the middle of the sink sat a large glass vessel, which seemed to be filled with water, but not like water.

At this time, Tang Yi was poking a glass pipe into the vessel, and his eyes were staring at a thin silver water-colored line in the pipe without blinking.

"I said, 'What are you doing here?'

"On the rocks, what nonsense!"

"Good...... Okay, on the rocks, on the rocks. ”

Over there, Tang Yi was already extremely focused, and put the thin pipe towards Lao Jia, "Take it." ”

Lao Jia hurriedly put down the beaker and took the glass tube. was about to be dragged out of the "water", but was stopped by Tang Yi's loud shout.

"Don't move, hold on."

Lao Jia rolled his eyes, he really became a subordinate, and he still had to hold on.

....

Handing over the glass tube to Lao Jia, Tang Yi poured out his hand and picked up another smaller beaker on the stone platform, which contained white fine noodles, like refined salt.

I was about to go to Riga, but I heard the door creak open again.

Tang Yi didn't even think about it, "Two people are enough, get out!" ”

Uncle Cao Guo at the door was stunned, his eyes straight.

This picture is a bit beautiful, Yang Wenguang is holding an ice bucket and "playing in the water", Jia Changchao is holding his arms and tilting his body....

"What is this for? I said, you can't do it later! ”

Cao Yan's voice made Tang Yi frown and slowly straighten his waist. When he saw that the two people on the side were Yang Wenguang and Lao Jia, his eyes widened, "Why are you here?" ”

"Get out, get out!"

Hey, the two of them almost didn't throw the guy in their hands on Tang Yi's face!

After supporting us for a long time, you don't recognize people when you raise your face?

"It's not a joke, you all go out."

Tang Yi emphasized it again, but Cao Tong listened to the music.

Not just a joke? In this house, a prime minister, a general, and a prince outside, three bigwigs are playing in the water here around a pool......

didn't take Tang Yi's words seriously at all, and stepped forward, "What the hell are you doing?" ”

Tang Yi is so angry, there is no one who is obedient.

Seeing that Lao Jia and Yang Wenguang didn't mean to leave, Tang Yixin said, don't you go, right? If something really happens, everyone will go to heaven together. Anyway, if Lao Tzu hangs up, you won't have a head.

looked at Cao Tong playfully, "Do you know what the master is best at?" ”

Uncle Cao Guo shook his head, "I don't know." ”

"Doing business?"

"Wrong!"

"The master is the most proficient in reading among businessmen, the most proficient in scolding, the most proficient in scolding, and the most proficient in being a prince, and the prince in ...... The best at making explosives! ”

"Dynamite?" , Yang Wenguang and Lao Jia couldn't understand, but Cao Tong was a spirit.

"The same thing you tried in the woods?"

"Yes!"

"Look, look."

Cao Tong was closer, and he had always wondered how that thing was so powerful.

Tang Yi shook his head speechlessly, just watch it if you like it!

He retracted his mind to the sink below, and took a good look at the glass pipe that Lao Jia was holding.

In fact, that thing is a mercury thermometer, although it has not yet been popularized to the point of the whole Song Dynasty, but it has been used a lot in Guanlan.

After making sure that the water temperature was right, Tang Yi began to add the white flour from the beaker to the utensils in the middle.

However, it is very slow, and it is very small at a time. Once you're done, stir gently and add again after a while.

"What is this?"

Cao Tong couldn't help but ask.

"What kind of glycerin is that, isn't it made of our Hualian glycerin?"

It's obviously not glycerin in that beaker!

"Pentaerythritol." Tang Yi opened his mouth and said a name that Uncle Cao Guo had never heard of.

"What...... What is pentaerythritol? ”

"You don't understand."

Well, Uncle Cao really doesn't understand.

"So isn't this nitroglycerin?"

Tang Yi shook his head, "No, it's another." ”

......

If you say what Madman Tang is best at, of course, it is not business, nor is he crazy, it is naturally the chemistry major he studied in his previous life.

You let Tang Yi do business and change history, he may have to think about it, but you let you make explosives......

Well, he can make you a hundred kinds of smoke with his eyes closed.

This is really not an exaggeration, explosives may be considered a very mysterious existence in the eyes of ordinary people in later generations.

However, in the eyes of a graduate student majoring in chemistry, it should be no different from oxygen preparation, which is the most basic chemical knowledge.

......

All kinds of explosives in later generations, whether high-explosive or low-explosive; whether it is a liquid explosive, or a solid explosive; Or a highly camouflaged disturbance explosive, in fact, it is a nitrate compound.

In other words, the vast majority of them are manufactured without nitric acid.

The best way to obtain nitric acid is to use natural resources and prepare it with sodium nitrate ore.

There are really not many things in the Great Song Dynasty, but it doesn't matter, although there are not many in the Great Song Dynasty, there are them on the other side of the sea!

Chilean saltpeter, which topped the Daimyo Mountain, was also the main raw material for nitric acid until the 21st century.

As long as he has nitric acid and gives him a cauldron, Tang Yi can show the art of explosion.

Here are a few examples: (What is said below is true, don't believe it.) ）

Tang Yi has already produced nitric acid-glycerin, as long as there is glycerin and nitric acid, plus common sodium carbonate and easily available sulfuric acid, it can be manufactured.

The only thing to pay attention to is the temperature during the reaction, which is the only difficulty with nitric-glycerin.

Simple, right?

Wrong! It's much cheaper and less difficult than that.

Take potassium nitrate, for example.

How simple is this thing? As I said before, give me a pot and give you an art of exploding, just take the pot and boil the dirt.

Of course, this is not ordinary soil, but old and rotten soil with old and rotten animals and plants, such as manure heaps, farmland, grain mounds, and cemeteries.

That's right, it's actually a garbage heap, or...... Or the biogas digester slag that every family in the Great Song Dynasty has.

Take this garbage back, boil it in water, filter the dirty water after boiling, remove sodium crystals, that is, salt, and the rest of the stuff doesn't have to be disposed of, just explosives.

Not only can it be used as an explosive, but it is also a strong oxidant. Soaking the cotton thread in potassium nitrate solution for half an hour and taking it out to dry is the best fuse.

Simple, right? It's just a little disgusting to make.

......

Hehe, there's something even more disgusting.

Human urine and animal urine are collected and boiled until only one-tenth remains, and then mixed with nitric acid.

You don't need to think about how much to add, you don't need to consider the reaction temperature, you don't need to think about the explosion, just add it. Then filter out the precipitate after the reaction, and this thing can be used as explosives, which is called urea nitrate.

Of course, if you think the above two are too dirty, you can also change to something else, such as using medicinal herbs as explosives.

Tang Yi can make wine for the willow bark of Yin Zhu and Wu Yuzhi for gout.

The willow bark is boiled in water, then purified with alcohol, and sulfur and potassium nitrate are added. This is called picric acid, and it was a low-explosive charge that was commonly used during World War I.

......

And also.

Before, Tang Yi asked Uncle Cao Guo to buy cotton in the Western Regions, not to make clothes, cotton can also be used to make explosives.

Soak cotton in a mixture of nitric acid and sulfuric acid for a while, and take it out is nitrocellulose, and increasing stability through water is smokeless gunpowder.

And thunder mercury ....

Mercury, nitric acid and alcohol, extremely sensitive, used as a primer, a collision will be fried!

......

——————————

So, explosives are really not high-end goods.

I'm afraid that you understand, as long as you know how to do it, let alone the Great Song Dynasty, even if you send it back to prehistory, you can blow up the primitive people crying dad and calling mom.

However, Tang Yi is also afraid of this. What if outsiders also understand? If you blow it up on both sides, it's not fun.

The reason why I didn't dare to take it out with nitric acid-glycerin was because I was afraid of this.

To put it bluntly, there is no difficulty in nitric-glycerin except for the complex reaction temperature in the production process.

If others want to learn, they don't need to do any spies to steal secrets, as long as they are not afraid of death and use people to fill in, they will be able to test out the correct reaction process sooner or later.

Moreover, the raw materials used are too conspicuous. A huge amount of glycerin is shipped to the explosives factory, and who doesn't know how this thing came about?

Therefore, Tang Yi chose the most difficult one.

In addition to the reaction temperature is as harsh, the main thing is that the raw materials are currently unlearned.

This explosive is called: Tai'an.

Written in English: PETN

Chemical name: pentaerythritol tetranitrate.

As for the power, it is especially higher than the TNT of later generations.

.....

It's not that Tang Yi is arrogant, if he doesn't say it, even if this thing goes a few hundred years, others won't be able to learn it.

The reason is simple, it's on this white powder in his hand now.

This thing is called: "pentaerythritol", an organic compound.

Formaldehyde and acetaldehyde, which are raw materials used for manufacturing, are also organic compounds that are absolutely unavailable in nature.

He really doesn't believe it, you don't even know basic chemistry, and if you can figure it out by yourself, you'll be damned.

......

At this time, Uncle Cao Guo, Jia Changchao, and Yang Wenguang, the three of them stared at Tang Yi making explosives here.

....

It's so anxious to see.,This fucking is embroidery, right?

Although the small beaker is not big, it also contains a lot of white noodles, and the amount of nitric acid that Tang Yi added back to it was not even a small pinch, when did he have to add it?

Uncle Cao Guo couldn't stand it anymore, "This grinding, why don't you just pour it in!?" ”

Tang Yi glared at him and didn't speak, still unhurried, still adding a little bit back and forth. It took more than a quarter of an hour, and the white flour in the beaker was not even a third of it.

This goods....

The thing finally stopped, and looked straight at the sky......

Oh go, Uncle Cao Guo couldn't bear it anymore, "No, you still can't get it?" ”

"Rush to death!"

Tang Yi glared at him again, "What are you anxious about?" ”

Uncle Cao Guo was not convinced, "Won't it be over if you just pour it and stir it up!?" ”

Tang Yi shook his head and sighed, "Ignorance is terrible! ”

Pointing to Lao Jia's hand that was already cramping, he said, "Do you see the red line on the thermometer?" ”

"Ah, I see!" Cao Yan lay on Lao Jia's hand and took a closer look. "Isn't that right? It's pressing the red line. ”

"In a little while, the four of us will go to Hades together."

My mother-in-law, Uncle Cao Guo shuddered and took a few steps back.

Stared at Tang Yi, then at Lao Jia and Yang Wenguang, "What ......?"

"Anyway, I don't have anything to do here, a certain family is out waiting for you."

......

After writing it, I still feel a little uncertain.,Can this thing be written.... Hurry up and read the pull-down, and change it in a few days.

I can't sit still a little bit, it should be so much for today, everyone has a ticket and throw some tickets!
