Title:
多孔質フッ化カルシウムの製造方法、水素化反応用触媒及びトリハイドロフルオロカーボンの製造方法
Document Type and Number:
Japanese Patent JP3994123
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To produce porous calcium fluoride having a larger surface area than that of conventional one, to provide its producing method, to produce a carried catalyst (in particular, a catalyst for a hydrogenation reaction) of which the carrier is porous calcium fluoride and superior in activity, selectivity and durability, and to provide a method for producing trihydrofluorocarbon using the catalyst. SOLUTION: Porous calcium fluoride having BET surface area of 20-200 m<2> /g is produced by a reaction of soda lime with hydrogen fluoride. The carried catalyst (catalyst for hydrogenation reaction) comprises a metal or a metal compound on porous calcium fluoride carrier. Trihydrofluorocarbon (2) is produced by contacting fluoroalkene (1) with hydrogen in the presence of the catalyst. (In the formula, X denotes a halogen atom, Rf1 and Rf2 denote fluorine or a parafluoroalkyl group, Rf1 and Rf2 may be connected and form a ring.).
