Emperor Chongzhen of the Ming Dynasty

Chapter 375 The Explosion of the Gunpowder Bureau

The violent explosion shocked everyone present.

Even Zhu Youjian was a little terrified.

Jin Yiwei, who was in charge of defending Zhu Youjian's safety, commanded the officer, Wang Zide, needless to say, and a dozen Jin Yiwei pulled out their knives on the spot and surrounded Zhu Youjian.

But only for a while.

When the rustling yellow leaves fell to the ground, Zhu Youjian also recovered his composure, and even became a little curious.

Only Song Yingxing and Bi Maokang were still in panic. They didn't know if it was an earthquake or someone deliberately made an explosion to startle them.

At this time, Fang Yizhi, who was accompanying him, ran over: "Return to Your Majesty, it was the Wang Gong Factory and the Gunpowder Bureau that exploded, directly blasting the ground into a big hole."

"Wang Gong Factory and Gunpowder Bureau are now in charge of Sun Heding."

"Hey, what is this Sun Heding doing? Doesn't he know that His Majesty is coming today?"

Song Yingxing was a little annoyed.

"It's okay, go and have a look."Zhu Youjian said with a smile, and then he lifted his feet first, and Song Yingxing and others hurriedly followed: "Your Majesty, you'd better not go."

"What are you afraid of? Is it possible that his Sun He Ding can make such a loud explosion again? If he can, then I have to take a look."

Zhu Youjian remembered that during the Tianqi period, there was a huge explosion in the Wang Gong factory in Daming.

Although he didn't know the reason that time, it's still an unsolved mystery so far.

But today's explosion, he didn't want to miss it.

As soon as Zhu Youjian came to the Gunpowder Bureau, he saw that the explosion site in front of the Gunpowder Bureau was full of broken bricks and glass slag, and a dozen fat pigs were blasted to bloody blood.

There was indeed a large kang left after the explosion on the ground, and the choking white smoke went straight into the nostrils, and everyone present couldn't help covering their noses.

Zhu Youjian was ecstatic for a while, thinking about what kind of high explosive Sun Heding made, it was so powerful, it was more powerful than black powder at first glance!

"Where's Sun Heding? Tell him to come see me immediately!"

Zhu Youjian asked aloud.

"Your Majesty, forgive me, I am in front of you." At this time, a human voice came from the ground.

Zhu Youjian looked down, but saw that Sun Heding was lying on the ground.

Sun Heding was covered with dead grass, leaves and soil, and when he stumbled up, he could still see the bloodstains on his face.

"Sun Heding, what are you doing?"

Song Yingxing asked in a harsh tone, but because Emperor Chongzhen Zhu Youjian was here, he tried his best to suppress his anger and did not question Sun Heding loudly.

"Old Song Ge, what are you talking about?" Sun He Ding looked at Song Yingxing and moved his ears closer.

"Your Majesty, forgive me." Song Yingxing cupped his hands to Zhu Youjian, then leaned into Sun Heding's ear, and asked loudly, "I asked you what you were doing, what happened to the explosion just now!"

"Explosion?" Sun Heding finally heard what Song Yingxing said.

"It seems that his ears were damaged by the shock. He is so close to the explosion site, and he doesn't know some protective measures. It's normal. I just hope it can recover. In the future, remember that you must open up when you encounter an explosion at such a distance. Mouth."

As he said that, Zhu Youjian hurriedly asked Sun Heding loudly if there were any casualties and the reason for the explosion.

"Returning to Your Majesty, I thought that since I am in charge of the Gunpowder Bureau, I want to develop gunpowder, but now there is no room for progress no matter how I redesign the ratio of gunpowder. I heard His Majesty said that gunpowder also has nitrated gunpowder and smokeless gunpowder. I thought that since cotton can be washed with nitric acid and sulfuric acid to obtain gun cotton, and gun cotton can already explode and is now used as a good lead, is it possible to get out the nitrated gunpowder first?
Your Majesty, you also said that adding glycerin to nitric acid can make a liquid called glycerin trinitrate. You said that it is easy to produce a violent explosion, which is much more powerful than the current gunpowder. I wanted to try it, and found it. Several supervisors and former alchemy priests worked together to make this trinitroglycerin with vinegar, lard and caustic soda. "

Hearing what Sun Heding said, Zhu Youjian nodded: "But I also approved it in your memorial. This thing is very dangerous. It can explode violently with a slight vibration. I also approved three cautions on it. Don't you remember?" ?"

"Wei Chen naturally remembered it, but Wei Chen just wanted to see how violent the explosion was, and thought that His Majesty just came here today, so he just wanted to test it out for His Majesty to see, but who would have thought that the effect would be really good , and the smoke and dust is much less than black powder, maybe we can really make smokeless gunpowder with this!"

Sun He Ding laughed as he spoke, revealing a mouthful of white teeth on his black face.

Zhu Youjian smiled slightly. He didn't expect that Sun Heding felt excited instead of scared. It seemed that he was really interested in these.

Zhu Youjian was not surprised that Sun Heding produced glycerin trinitrate.

This experiment is indeed not too difficult. It is nothing more than reacting nitric acid and glycerin, and glycerin is also easy to extract. It is heated and reacted with lard and caustic soda, and then cooled to make it layered. The solid can be used to make soap, while the liquid It is a mixture of glycerin and caustic soda solution.

Caustic soda can be neutralized with acetic acid, sodium nitrate can be removed by recrystallization, and then glycerin can be obtained by removing water with quicklime.

This is why Sun Heding said to use lard, vinegar and caustic soda.

As for caustic soda, it is sodium hydroxide. This highly corrosive alkaline substance can already be produced in Daming.

Needless to say nitric acid, Tiangong Kaiwu has recorded various nitrate preparation methods. Nitrogen dioxide can be obtained by calcining nitrate at high temperature, and nitrogen dioxide can react into nitric acid when it meets water.

These experimental theories are not difficult, and Zhu Youjian also helped Sun and Ding to popularize them a lot, but the key is that these experiments are very dangerous, involving two strong acids and strong bases.

Zhu Youjian didn't expect that Sun Heding would actually rush to do it, and even get out the nitroglycerin.

"Is this nitroglycerin still available now?" Zhu Youjian asked loudly again.

"No, Your Majesty said that this thing will explode when you touch it lightly, so Weichen simply built an experimental shed in the explosion site, and made this thing in the shed, put nitric acid in a glass basin, and slightly In fact, I didn't know how much glycerin to add, I added it anyway, and then I ran outside and took aim with a musket and fired a shot. The musket was specially approved by Bi Butang, but I never thought of just firing a shot. It exploded with such great power, and now the glass shards all over the floor are the wreckage."

Sun Heding pointed to his face as he spoke: "These scars are also scratched by glass shards."

"Your Majesty, I want to subdue this glycerin trinitroglycerin as soon as possible to apply for a special approval project fund. I don't want him to explode so easily. Let him be more obedient. I believe that as long as this is made into gunpowder, it will definitely be better than the current gunpowder! "

Sun Heding didn't care about the burning scars on his face, so he hurriedly asked Zhu Youjian for money.
