Document Type and Number:
Japanese Patent JP5807690
Kind Code:
B2
Abstract:
The present invention provides a method for producing a fluorine-containing olefin, the method comprising reacting a chlorine-containing compound represented by a specific formula with anhydrous hydrogen fluoride in the presence of a chromium atom-containing fluorination catalyst, the reaction being carried out at a temperature within the range of 200 to 350°C in the presence of 0.0001 to 0.03 mol of molecular chlorine per mol of the chlorine-containing compound. The present invention is capable of achieving the effect of suppressing catalyst deterioration, maintaining the starting material conversion and the target product selectivity within excellent ranges, and reducing adverse effects caused by the use of a large amount of non-condensable gas.
