Chapter 13

Gu Lanxi was surprised. Although many words were still incomprehensible, he understood the word "poisoning".

"What, toxic? Let me do it. "

Ye Liuli shook his head. "It's not that I look down on death, but I just heard my uncle talk about refining salicylic acid. I've never tried it. I still need to explore. How can I guide you? Since it's doomed to be poisoned, I'll do it myself, and you'll all step down. "

"No! The princess must not be poisoned Gu Lanxi's voice is firm.

Ye Liuli chuckled, "I can't be poisoned, can you? If you know I poisoned you, don't you kill me? As the saying goes, brothers are like brothers and women are like clothes, aren't they? "

Gu Lanxi laughed, "the princess can see it."

Ye Liuli shrugged, "can't you see it? How many years of love between you and your Lord, I've known him for two days? If we both fall into the water at the same time, he will save you, not me. "

“……” Although the truth is such a truth, but Gu Lanxi how to listen to how uncomfortable, why this friendship from ye Liuli mouth, add some ambiguity?

Finally, salicylic acid was extracted by Ye Liuli and Gu Lanxi.

Maid mother heard that "toxic", this want to run, listen to Ye Liuli request to leave, but also like to fly away.

After the time of incense burning, the boiling water of willow bark has been boiling for a long time. With the heating, the liquid is continuously evaporating, and the liquid is more concentrated and the volume is reduced.

"Commander Gu, step back and try not to touch the water vapor," said Ye Liuli in a calm voice. "The water vapor containing salicylic acid is corrosive to some extent, which is harmful to respiratory tract and retina."

Gu Lanxi wanted to retort, but the tone of the other side was irresistible and convincing.

"Be careful, princess." I just stepped back two steps.

Gu Lanxi pulled a handkerchief to cover his mouth. He stepped back as far as he could, leaving only a hand wrapped with a towel and stirring in the pot with a spoon.

Time goes by.

Finally, the liquid in the pot is completely dried. On the wall of the iron pot, there is a layer of white crystal of Bobo, which is salicylic acid.

Salicylic acid is not only the raw material of pharmaceutical industry, but also used to prepare aspirin, sodium salicylate, salicylamide, Zhitongling, phenyl salicylate, xuefang-67 and other drugs. It is used to prepare mordant dyed pure yellow, direct brown 3gn and acid chrome yellow in dye industry. It can be used as delay agent and antiseptic for rubber vulcanization. It is also widely used in cosmetics, as a preservative in cosmetics, and even in food.

This kind of salicylic acid can not be used directly. It needs to be further purified to become phenol. Then it is purified and reduced to aminophenol by heating hydrochloric acid and iron powder. The final product is modern daily medicine The rudiment of paracetamol.

Ye Liuli swears that this is the worst and most dangerous experiment she has done since she came into contact with chemistry experiment in junior high school, but she has to do it.

The time of the day almost passed in the blink of an eye, so it was evening.

when ye Lai glass collected the final product in the bottle, it almost burst into tears. It felt like Columbo discovered the new American continent, as if Robinson had created a new world on the desert island.

All of a sudden, there was a noise from afar, and then someone came running, "master strategist, it's not good!"

Ye Liuli looked up and saw that he was one of the two disciples of the military doctor. Did the king have any accident?
