Title:
PERFLUOROALKYL HALIDE AND ITS DERIVATIVE
Document Type and Number:
Japanese Patent JP3231844
Kind Code:
B2
Abstract:
PURPOSE: To provide a perfluoroalkyl halide and its deriv. useful as a surfactant to be used to improve the surface properties of fiber products or substrates such as paper and leather.
CONSTITUTION: A mixture of perfluoroalkyl halide compds. is disclosed. The perfluoroalkyl halide compds. have (A) perfluoroalkyl groups comprising preferably 4 to 20, especially 4 to 10 carbon atoms completely fluorinated, 60 to 90% of the carbon atoms form a straight-chain structure, (B) halogen atoms selected from Cl, Br and I, and (C) alkylene groups which are free from fluorine and have at least two connected carbon atoms, one of which is bonded to the perfluoroalkyl group and the other is bonded to the halogen atom. The mixture consists of, for example, a compd. expressed by formula I (Rfs is straight-chain perfluoroalkyl: R1 is 1 to 4C org. part, H; R2 is 0 to 20C alkylene; X is halogen) and a compd. expressed by formula II (Rfb is branched perfluoroalkyl).
