Gu Yanxi was taken aback. Although many words were still incomprehensible, he understood the word "poisoning".
"What, poisonous? Let the subordinates do it."
Ye Liuli shook her head, "It's not that I treat myself as if I'm dead, but just that I heard that. I have not tried to refine salicylic acid myself. I still need to explore it myself. How can I guide you? Since there is a risk of poisoning, I'll do it myself, and you all step back. "
"No! The princess must not be poisoned!" Gu Yanxi's voice was firm.
Ye Liuli smiled, "I can't be poisoned, can you? If your prince knew that I had poisoned you, wouldn't he kill me? As the saying goes, brothers are like hands and feet and women like clothes, aren't they?"
Gu Yanxi laughed, "The princess thinks too much."
Ye Liuli shrugged. "Can't you see, how many years have you had a relationship with your family's Lord, I have only known him for two days? If we both fell into the water at the same time, he must save you but not me."
"..." Although there was such a truth, how could Gu Yanxi listen to it? Why is it that this friendship spoken out of Ye Liuli's mouth, added some ambiguity?
Finally, the salicylic acid was refined by Ye Liuli and Gu Yanxi together after much arguing.
The girl heard that it was "toxic", so she wanted to run, and when Ye Liuli asked her to leave, she fled.
After about 2 hours, the water of boiling willow bark had started boiling for quite a while. With the heating, the water continuously evaporated, the liquid in the iron wok becomes more concentrated and the volume decreases.
"Gu Jun, step back, try not to touch the water and gas," Ye Liuli's voice was calm. "Water vapor containing salicylic acid is corrosive and harmful to the respiratory tract and the retina."
Gu Yanxi wanted to refute, but the other person's tone was convincing with an irresistible majesty.
"The princess should also be careful." He simply stepped back two steps.
Gu Yanxi pulled a piece of mask unto his mouth, leaning back as far as possible, leaving only a hand wrapped in a towel, holding the spoon and stirring continuously in the pot.
Time passed minute by minute.
Finally, the liquid in the pot was completely dried. On the wall of the iron pot, there was a wave of white crystals. This crystal was salicylic acid.
Salicylic acid is not only a raw material for the pharmaceutical industry, it is used for the preparation of aspirin, sodium salicylate, salicylamide, analgesic, phenylsalicylic acid, and Xuefang-67. Used in the dye industry to prepare mordant pure yellow, direct brown 3GN, acid chrome yellow. Used as a rubber vulcanization retarder and disinfectant preservative. It is also widely used in cosmetics, as a preservative in cosmetics, and even in food.
This salicylic acid cannot be used directly. It must be further purified to become phenol, and then aminophenol is reduced by heating and purification with hydrochloric acid and iron powder. The final product is the prototype of modern daily medicine ... paracetamol.
Ye Liuli sweared that this was the worst and most dangerous experiment she had ever done since she was exposed to chemistry experiments in junior high school, but she had to do it.
The day passed almost in the blink of an eye, and it was so late in the evening.
When Ye Liuli collected the final product in a bottle, she almost cried with excitement, feeling as if she was Columbus who discovered the New World of America, as if Robinson opened up a new world on a desert island.
Suddenly there was a loud noise from afar, and then someone ran over, "Division Master it's not good!"
Ye Liuli looked up and gave a smooth look. It turned out that he was one of the two disciples of the military doctor. Was there something wrong with the Dongfang ?
