<p>The process of preparing benzotrifluoride which involves reacting benzotrichloride with hydrogen fluoride in a reaction zone at a pressure between 20 and 45 atm. and at a temperature between 85 DEG and 100 DEG C. The reaction is conducted in the presence of a catalyst consisting of a mixture of aluminum chloride and activated charcoal. On a stoichiometric basis, the amount of hydrogen fluoride is 1.0 to 1.1 times the amount of the benzotrichloride. The benzotrichloride, catalyst and hydrogen fluoride are present as an admixture or intermixture having a Reynolds number between 65,000 and 100,000. The reaction can be conducted in a stirring vessel equipped with a stirring mechanism.</p> |
