Process For Preparing 3,3,3-Trifluoropropene

摘要

The invention provides a process for preparing 3,3,3-trifluoropropene (1243zf), the process comprising contacting a compound of formula CX3CH2CH2X or CX3CH═CH2, with hydrogen fluoride (HF) in the presence of a zinc/chromia catalyst, wherein each X independently is F, Cl, Br or I, provided that in the compound of formula CX3CH═CH2, at least one X is not F.
