Abstract

The experimental conditions (temperature, reaction time, amount of hydrogen fluoride (HF)) for the comparison of the performances of various Lewis acids in the liquid phase fluorination by HF of the trichloromethoxy-benzene were determined by using SbCl5 as the reference catalyst. After 1h reaction at 50° C, C6H5OCCl3 was totally converted into C6H5OCF3 requiring only 2mol% of SbCl5 and a stoichiometric amount of HF. The most ...
