Claim Text:
1. A method for producing 2,3,3,3-tetrafluoropropene, comprising: reactively fluorinating a halopropane and/or halopropene to 2,3,3,3-tetrafluoropropene using hydrogen fluoride; recovering a gaseous stream obtained from the reaction; cooling and partially condensing the gaseous stream obtained from the reaction, to give a partially condensed stream; separating the partially condensed stream into a gaseous fraction and a liquid fraction; compressing the gaseous fraction to give a compressed gaseous fraction; compressing the liquid fraction to give a compressed liquid fraction; distilling the compressed gaseous fraction and the compressed liquid fraction to give a 2,3,3,3-tetrafluoropropene stream, a hydrochloric acid stream, and a stream of unreacted hydrogen fluoride.
