PROCESS FOR PRODUCING FLUORINE-CONTAINING OLEFIN

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.

Compositions

A composition comprising HCFO-1233xf and at least one additional compound selected from the group consisting of HCFO-1233zd, HCFO-1232xd, HCFO-1223xd, HCFC-253fb, HCFC-233ab, HFO-1234yf, HFO-1234ze, ethylene, HFC-23, CFC-13, HFC-143a, HFC-152a, HFO-1243zf, HFC-236fa, HCO-1130, HCO-1130a, HFO-1336, HCFC-244bb, HCFC-244db, HFC-245fa, HFC-245cb, HCFC-133a, HCFC-254fb, HCFC-1131, HCFO-1242zf, HCFO-1223xd, HCFC-233ab, HCFC-226ba, and HFC-227ca.

PROCESSES FOR PRODUCING 2-CHLORO-1,1,1,2-TETRAFLUOROPROPANE AND 2,3,3,3-TETRAFLUOROPROPENE

To provide processes for efficiently and economically producing 2-chloro-1,1,1,2-tetrafluoropropane (R244bb) and 2,3,3,3-tetrafluoropropene (R1234yf) in an industrially practical manner. A process for producing 2-chloro-1,1,1,2-tetrafluoropropane, which comprises a chlorination step of reacting 1,2-dichloro-2-fluoropropane and chlorine in the presence of a solvent under irradiation with light to obtain 1,1,1,2-tetrachloro-2-fluoropropane, and a fluorination step of reacting the 1,1,1,2-tetrachloro-2-fluoropropane obtained in the chlorination step and hydrogen fluoride in the presence of a catalyst to obtain 2-chloro-1,1,1,2-tetrafluoropropane, and a process for producing 2,3,3,3-tetrafluoropropene, which comprises dehydrochlorinating it in the presence of a catalyst.
