The preparation of CF3COCl through reaction between CF3CCl3 and SO3 was investigated with particular reference to the following operating parameters: catalyst type and concentration, molar ratio C2Cl3F3/SO3 and composition of the isomeric mixture CF3CCl3/CClF2CCl2F. Such preparation was first investigated either batchwise or semi-continuously, in order to define at best the above parameters. It was then effected continuously on proper equipment, which allowed to separate the CF3COCl at a degree of purity adequate to its direct use in the preparation of trifluoroacetic compounds.

Abstract
The preparation of CF3COCl through reaction between CF3CCl3 and SO3 was investigated with particular reference to the following operating parameters: catalyst type and concentration, molar ratio C2Cl3F3/SO3 and composition of the isomeric mixture CF3CCl3/CClF2CCl2F. Such preparation was first investigated either batchwise or semi-continuously, in order to define at best the above parameters. It was then effected continuously on proper equipment, which allowed to separate the CF3COCl at a degree of purity adequate to its direct use in the preparation of trifluoroacetic compounds.File in questo prodotto:
