Title:
A manufacturing method of fluorine-containing Olefin
Document Type and Number:
Japanese Patent JP6233352
Kind Code:
B2
Abstract:
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.
