PROCESS FOR THE PRODUCTION OF 1,1,1,2,2-PENTAFLUORO- 3-CHLOROPROPANE

摘要

A process for the manufacture of CF3CF2CH2Cl comprising contacting CH2ClF with CF2=CF2 in the presence of a catalytically effective amount of an aluminum halide composition having a bulk formula of AlClxBryF3-x-y wherein the average value of x is 0 to 3, the average value of y is 0 to 3-x, provided that the average values of x and y are not both 0, to produce CF3CF2CH2Cl with a selectivity of at least 70%.
