12 difluorobenzene Cas No
Looking for the Book of 1,2-difluorobenzene
At some point, I wanted 1,2-difluorobenzene (12-difluorobenzene Cas No). This thing is also unique in nature and widely used, and it is quite needed for various chemical things.
He sent servants to search around, to consult the workshops of medicine shops, and to visit the elders who studied in the house. At first, the servants were all confused, and they didn't know what this was. Yu also worried, I was afraid it would be hard to find.
However, there is no way out of the world. One day, a servant returned to report, and he ran around the west of the city. I heard the shopkeeper say that he had seen this thing. Yu Xinxi was happy, that is, ordered the servant to go again and ask about its source. When the servant returned, he said, "Shopkeeper Yun, this is obtained from a skilled craftsman in the north, who is good at making all kinds of strange medicines and foreign bodies."
Yu then repaired a book, and sent the servant to the north quickly to ask for the craftsman. The servant traveled for several days, and finally arrived at his place. The craftsman read the book, and smiled and said, "What kind of medicine do you need?" The servant told the truth. The craftsman ordered the disciple to take 1,2-difluorobenzene to the servant, and the servant brought it back.
The rest of this thing is like a treasure. Since then, everything has gone well, and it all depends on the power of 1,2-difluorobenzene.
