How much do you know about Benzotrifluoride(CAS:98-08-8)

Chemical Property:Benzotrifluoride(CAS:98-08-8) appears as a colorless liquid with an aromatic odor. Insoluble in water, soluble in ethanol, ether, acetone, benzene, carbon tetrachloride, etc.

 Value:Benzotrifluoride(CAS:98-08-8) can be used as an intermediate in organic synthesis, dyes, pharmaceuticals, vulcanizing agents, accelerators, and in the manufacture of insulating oils. It can be used for determining the calorific value of fuels, preparing powder fire extinguishing agents, and also serving as additives for photodegradable plastics.Benzotrifluoride is an important intermediate in fluorine chemistry, which can be used to prepare herbicides such as fluchlor, fluorochlor, and pyrfluchlor, and is also an important intermediate in medicine.

Production Method: 1. Benzotrifluoride is prepared from ω,ω,ω- Benzotrifluoride is obtained by reacting with anhydrous hydrogen fluoride. ω,ω,ω- The molar ratio of Benzotrifluoride to anhydrous hydrogen fluoride is 1:3.88. The reaction takes place for 2-3 hours at a temperature of 80-104 ℃ and a pressure of 1.67-1.77 MPa. The yield was 72.1%. Due to the cheap and easy availability of anhydrous hydrogen fluoride, easy equipment solution, no need for special steel, low cost, and suitable for industrialization. 2. By ω,ω,ω Chemicalbook-Benzotrifluoride is obtained by reacting with antimony Benzotrifluoride. take ωωω Benzotrifluoride and antimony Benzotrifluoride are heated and distilled in a reaction pot, and the distillate is the crude trifluoromethylbenzene. Wash with 5% hydrochloric acid, add 5% sodium hydroxide solution, heat and distill, and collect the fraction at 80-105 ℃. Separate the upper liquid, dry the lower liquid with anhydrous calcium chloride, and filter to obtain trifluoromethylbenzene. The yield is 75%. This method consumes antimony compounds and has a high cost, which is generally more convenient to use only under laboratory conditions.

Preparation:Benzotrifluoride(CAS:98-08-8) is an organic intermediate that can be obtained by chlorination and fluorination of toluene.

Storage and transportation characteristics: warehouse ventilation, low-temperature drying; Store separately from oxidants and acids
