Title:
含フッ素プロペンの製造方法
Document Type and Number:
Japanese Patent JP7287391
Kind Code:
B2
Abstract:
The present invention provides a production method for efficiently obtaining a fluorine-containing propene having a -CF= structure with high yield with use of a fluorine-containing propane that has a -CF2- structure in each molecule as a starting material. A method for producing a fluorine-containing propene, by which a fluorine-containing propene represented by formula (B) is obtained by subjecting a fluorine-containing chlorine-containing propane represented by formula (A) to a defluorination dechlorination reaction in the presence of a reducing agent that is composed of at least one element selected from among alkaline earth metals and transition metals. Formula (A): CY3-CF2-CClX2 Formula (B): CY3-CF=CX2 In formula (A), each one of two X moieties independently represents F, Cl or H; and each one of three Y moieties independently represents F or H, excluding the cases where both of the two X moieties represent H. In formula (B), the X and Y moieties are as defined in formula (A).
