Abstract
Official abstract text for this publication.
The present disclosure provides a fluorination process which involves reacting a hydrohaloalkene of the formula R f C—Cl═CH 2 with HF in a reaction zone in the presence of a fluorination catalyst selected from the group consisting of TaF 5 and TiF 4 to produce a product mixture containing a hydrohaloalkane of the formula R f CFClCH 3 , wherein R f is a perfluorinated alkyl group.
First claim
Opening claim text (preview).
What is claimed is: 1. A process comprising: reacting a hydrohaloalkene of the formula R f CCl═CH 2 with HF in a reaction zone in the presence of a fluorination catalyst selected from the group consisting of TaF 5 and TiF 4 to produce a product mixture comprising a hydrohaloalkane of the formula R f CFClCH 3 , wherein R f is a perfluorinated alkyl group, in an amount effective to form R f CFClCH 3 without substantially forming R f CF 2 CH 3 or R f CHClCH 2 F.…
