Abstract

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.
