Title:
PREPARATION METHOD FOR PERFLUOROOLEFIN OLIGOMER AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/035876
Kind Code:
A1
Abstract:
The present invention relates to the technical field of the fluorine chemical industry, and disclosed are a preparation method for a perfluoroolefin oligomer and an application thereof. The preparation method comprises: selecting a combination of two or more raw material monomers selected from among the following (i) and (ii) undergoing an oligomerization reaction under the catalysis of a metal fluoride salt to obtain a perfluoroolefin oligomer product the total carbon number of which is not less than 7, wherein (i) is tetrafluoroethylene, a tetrafluoroethylene oligomer or a mixture thereof, and (ii) is hexafluoropropylene, a hexafluoropropylene oligomer or a mixture thereof. The present application solves the difficult problem of high-selectivity preparation of perfluoroolefin oligomers having high carbon numbers.
