US 2026/0049047 A1 · METHOD OF PRODUCING FLUOROOLEFIN

Abstract

A method of producing fluoroolefin includes contacting a fluorocarbon represented by Formula (1): CX1X2F—CX3X4H with a catalyst to produce a fluoroolefin represented by Formula (2): CX1X2═CX3X4, and satisfies either (I) or (II). (I) The catalyst includes 65% by mass or more of α-alumina and has an amount of Lewis acid sites of from 0.005 to 0.10 mmol/g as measured by ammonia temperature-programmed desorption method. (II) A conversion rate 10 hours after contacting the fluorocarbon with the catalyst is from 7.0 to 13.0%, and a conversion retention rate, which is a ratio of the conversion rate 50 hours after contact to a conversion rate after 10 hours, is 69% or higher.
