(57) [Summary]nTetrafluoro useful as a raw material monomer for fluororesin Production of fluoroethylene and hexafluoropropylene Providing a method.nThe fluorine content is 30% by mass or more (R 1 CH 2 CH (R 2 ) CH 2 OCO) n Q in the liquid phase React with element (R 1F CF 2 CF (R 2F CF 2 O CO) n Q F And then decompose the ester bond to R 1F CF 2 CF (R 2F ) COF R by solving 1F CF = CF 2 Manufacturing method. n is An integer greater than or equal to 1. R 1 , R 2 Each independently represents a hydrogen atom Or a methyl group, at least one of which is a hydrogen atom. R 1F , R 2F Is a fluorine atom or trifluoromethyl Group. Q F Is a group in which Q is perfluorinated, and Is the same group as Q. |
