Title:
METHOD FOR PRODUCING PERFLUOROALKADIENE COMPOUNDS
Document Type and Number:
WIPO Patent Application WO/2018/143400
Kind Code:
A1
Abstract:
According to a method for producing perfluoroalkadiene compounds represented by general formula (1): CF2=CF-(CF2)n-4-CF=CF2 (1) [in the formula, n represents an integer of 4 or higher], wherein the method is provided with a reaction step for adding a nitrogen-containing compound to a solution of a compound represented by general formula (2): X1CF2-CFX2-(CF2)n-4-CF2-CF2X1 (2) [in the formula, n is the same as above; X1 may be the same or different, and represent a halogen atom other than a fluorine atom; and X2 represents a halogen atom], perfluoroalkadiene compounds can be obtained at high efficiency.
