I make a popular science video and all the emperors learn from it!

【History of phosphorus research:】

[Regarding the discovery of phosphorus, we have to start with the alchemy of the European Middle Ages. 】

[At that time, alchemy was in vogue, and it was said that if you found a kind of stone for a wise man, the philosopher's stone, you could turn the stone into gold, and ordinary lead and iron into precious gold. 】

[The alchemist is like a madman, using strange utensils and substances, in a dark hut, chanting incantations in his mouth, refining in the fire, stirring in the vat, and thinking about the person who turns stones into gold. 】

[In 1669, a merchant named Brand in Hamburg, Germany, found phosphorus in his urine. 】

[Each lab used at least 50~60 barrels of urine, and it took at least two weeks to complete. 】

【......】

Boy.

After reading the history of phosphorus research.

All the emperors were collectively dumbfounded!

Do you want them to collect urine???

Then from the inside of the urine, get the phosphorus out......

And looking at this pitiful yield, I'm afraid that even if I scavenge hundreds of latrines, I won't be able to get much phosphorus.

Ying Zheng waved 877 with an embarrassed face: "Cough, don't want the widow." "

Liu Bangren was stupid: "Ah, Xiao He, stop, don't go to the toilet to grab urine!"

Liu Che was speechless: "Everyone, although this phosphorus is good, it is not our thing after all." "

Li Shimin: "Cheng bites Jin! I order you to stop immediately, and you are not allowed to go to the thatched house without authorization..."

Wu Zetian: "It's really hard to speak, it's just that." "

Zhu Yuanzhang: "The grand occasion of our Ming Dynasty's harvest is gone?"

Zhu Di: "I don't want to speak, and I won't be afraid to wait, just stop." "

The emperors suddenly felt that phosphorus was a hot yam.

It's a loss if you lose it, but if you don't lose it...

Smelling commotion.

[Popular science continues.] 】

[Toxicological information of phosphorus:]

[The elemental nature of phosphorus is highly toxic, and white phosphorus is more toxic than red phosphorus. 】

[Without protection, people who work in an environment with white phosphorus can be chronically poisoned and lead to necrosis of the jaw (phosphorus jaw).] 】

[Phosphate esters are nerve agents and should only be handled by sufficiently qualified chemists.] 】

[Relatively speaking, inorganic phosphates are harmless, while excessive use of phosphate-containing fertilizers and detergents can lead to phosphate contamination. 】

【Storage:】

White phosphorus should be kept in water and must be submerged under water to keep out the air. Store in a cool, well-ventilated dedicated warehouse. The storage temperature should be kept above 1. Keep away from fire and heat sources. It should be stored separately from oxidants, acids, halogens, and edible chemicals, and should not be mixed. 】

[Red phosphorus is stored in a cool, ventilated warehouse.] The storage temperature is not more than 35, and the relative humidity is less than 80%. Keep away from fire and heat sources. It should be stored separately from oxidants, halogens, halides, etc., and should not be mixed. 】

【Shipping Method:】

[When transporting, the transport vehicle should be equipped with the corresponding variety and quantity of fire-fighting equipment, and leakage emergency treatment equipment. 】

[The exhaust pipe of the vehicle for the shipment of this product must have a fire arresting device.] 】

[During transportation, ensure that the container does not leak, collapse, fall, or damage. 】

[It is strictly forbidden to mix with oxidants, halogens, halides, etc.] 】

[During transportation, it should be protected from exposure to sun, rain and high temperature. Keep away from fire and heat sources during stopovers. Vehicles should be thoroughly cleaned after transportation. It is forbidden to slip when transporting by rail. 】

【......】

【Distribution:】

[There is no elemental phosphorus in nature, and phosphorus is widely distributed in a variety of minerals. 】

[Phosphate ore (apatite, calcium phosphate containing impurities) is an important source of phosphorus. 】

[Among them, Moluo Ge, Mao Xiong Guo and Mi Guo have found a large number of sedimentary phosphate ores. 】

(ccah) [The detailed geographical location of the three countries is shown on the world map, as follows:] (Read the violent novel, go to the Feilu novel network!)

【...】

All the emperors breathed a sigh of relief again.

Tell me earlier.

Phosphorus is extracted from the urine, which only accounts for a small proportion, and even if it is extracted, it cannot be preserved.

What really matters is the phosphate mine!!

Qin Dynasty.

Ying Zheng swept away the decadence, and he was so happy in his heart.

"Well, if you have phosphate rock, you can mine it. "

What surprised him the most was that there was a familiar word in the place where phosphate rock was abundant, rice country.

He couldn't remember how many times he had seen those two words.

And now, he finally let him know that the Americas are where the United States is located!

"Someone, get the world map!"

Soon, a carved map of the world appeared in his hands.

Ying Zheng took up the pen and marked the locations of the three countries. []

It is like a posture of incorporating the three countries into the territory of Qin.

Han dynasty.

Liu Che's heart was terrified, and he muttered: "Ahem, the phosphate mine is bound to win, what do you think?"

Just kidding, a gentleman is hard to chase.

What he didn't want was phosphorus, but he didn't say he didn't want phosphate rock.

Many ministers glanced at each other, and immediately knelt on the ground and shouted: "Your Majesty is wise, take down the phosphate mine, benefit the country and the people, there is no reason not to take it." "

They automatically ignore what His Majesty said before.

Liu Che took the world map and was surprised to find that the closest to the Han Dynasty was actually the Mao Bear Kingdom!

And by land, you can get there.

However, it is necessary to pass through the territory of the steppe people.

Ming dynasty.

Zhu Di couldn't help but be overjoyed.

He said that if he didn't force his courtiers to go to the hut to collect human urine, what did it matter if he issued a holy decree to attack other countries?

Since the light curtain popularized shipbuilding technology, the credit mall has put shipbuilding technical drawings on the shelves.

The shipbuilding technology of the Ming Dynasty can be described as unprecedentedly advanced!

Hang all the countries at this time!

In addition, in terms of weapons, it has thrown off a few streets from other countries!

There is no need to worry about domestic grain production, which is supported by potatoes, sweet potatoes and corn.

It's a good time to start the Age of Discovery!

Zhu Di looked at Zheng He, and his heart had already begun to lay out the future.
