Synthesis of Perfluorovinyl Ether Monomers

Application of perfluoro(2-propoxypropyl vinyl ether) (PPVE-2) in the synthesis of perfluoro(propyl vinyl ether) (PPVE-1)

A novel preparative method for the conversion of n-C3F7OCF(CF3)CF2OCF = CF2 (PPVE-2) into n-C3F7OCF = CF2 (PPVE-1) is reported. It includes the catalytic oxidation of PPVE-2 with molecular oxygen to furnish a mixture of carbonyl fluorides which are subjected to alkaline hydrolysis resulting in a mixture of salts. Subsequent thermolysis of those salts give rise to an inseparable mixture of PPVE-1 and perfluoro-2-propoxypropanoyl fluoride. Treatment of this mixture with sodium carbonate allowed to obtain sodium perfluoro-2-propoxypropionate and to isolate PPVE-1. Thermolysis of this sodium salt produced an additional amount of PPVE-1, so that the total conversion of PPVE-2 into PPVE-1 is accomplished in good yields. The reaction conditions, the choice of reagent as well as the course of competitive reactions are discussed.

Method for Preparing Fluorine-Containing Vinyl Ether

Provided is a method for preparing fluorine-containing vinyl ether. The method comprises: carrying out hydrolytic neutralization on a small molecular weight byproduct which is produced in the process of preparing perfluoropolyether or a perfluorinated surfactant by photooxidation of fluorine-containing olefin; and obtaining fluorine-containing vinyl ether by drying and cracking. The byproduct produced in the process of preparing perfluoropolyether or the perfluorinated surfactant is utilized, thereby solving the emission problem of industrial wastes, reducing environment pollution, and generating available fluorine-containing vinyl ether.
