A fluoropropene composition comprising Z-1,3,3,3-tetrafluoropropene, E-1,3,3,3-tetrafluoropropene, 1,1,3,3,3-pentafluoropropene, 2,3,3,3-tetrafluoropropene, and optionally 1,1,1,3,3-pentafluoropropane wherein the 2,3,3,3-tetrafluoropropene being present in an amount of 0.00001 to 1.0%. A method of producing the fluoropropene, methods for using the fluoropropene and the composition formed are also disclosed.

A method of producing fluoroolefin includes contacting a fluorocarbon represented by Formula (1): CX.sup.1X.sup.2FCX.sup.3X.sup.4H with a catalyst to produce a fluoroolefin represented by Formula (2): CX.sup.1X.sup.2CX.sup.3X.sup.4, and satisfies either (I) or (II). (I) The catalyst includes 65% by mass or more of -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.
