In the production of fluorine-containing olefins using a chlorine-containing alkane or a chlorine-containing alkene as a starting material, a process for producing a plurality of useful fluorine-containing olefins with high selectivity using the same raw material, the same equipment, and the same conditions is provided. The present invention provides a process for producing fluorine-containing olefins, the process comprising reacting a chlorine-containing compound represented by a specific formula and anhydrous hydrogen fluoride in the presence of oxidative gas and a fluorination catalyst, wherein the fluorination catalyst is a catalyst in which at least one metal element M selected from the group consisting of Group VIII and Group IX is present together with chromium. This production process can simultaneously produce two or more fluorine-containing olefin compounds, including HFO-1234yf and HFO-1234ze, with high selectivity.

REACTOR FOR LIQUID PHASE FLUORINATION REACTIONS

The present invention relates to a hydrofluorinating process which comprises reacting a fluoroolefin with hydrogen fluoride in the liquid phase in the presence of a hydrofluorination catalyst in the reaction zone of a reactor, said reactor comprised of a reactor body having a length to diameter ratio of about 2:1 or greater; a stirred reaction zone containing said hydrofluorination catalyst, which may be prepared in situ, at least one inlet for supplying said hydrogen fluoride and fluoroolefin to the reaction zone and at least one outlet for recovering said fluoroalkane, said stirrer disposed in the reaction zone and comprising a plurality of blades fixedly attached to shaft drivable by a motor, said blades extending from about the bottom of the reaction zone to about the top of the reaction zone and said shaft extending on a longitudinal axis from the bottom of the reactor to the top of the reactor, said stirrer being rotated at a speed sufficient to promote a swirling of the liquid to effect the occurrence of hydrofluorination reaction and minimize overfluorination.
