PERFLUORINATED CYCLE-CONTAINING TERTIARY AMINES AS BASE OF GAS-TRANSFERRING EMULSIONS (VARIANTS) AND METHOD FOR THEIR PREPARING Russian patent published in 2005 - IPC

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to novel perfluorinated cycle-containing tertiary amines of the general formula (1): wherein n = 1; m = 2 or 3; X means or and to a mixture of perfluorinated cycle-containing tertiary amines of the general formula (1) wherein n = 1; m = 2 or 3; X means or where at n = 1 Y means CF₃ and at n = 2 Y means F as a base for gas-transferring emulsions. Proposed compounds are similar by their physicochemical properties, in particular, by critical temperature dissolving in hexane. Properties of these compounds provide the improved homogeneity of fluorocarbon phase of emulsions and to enhance stability of emulsion particles stabilized with block-copolymer of ethylene oxide and propylene oxide and in the absence of toxicity for small and large animals. Also, invention relates to a method for preparing perfluorinated cycle-containing tertiary amines of the general formula (1) by electrochemical fluorination of p-piperidinoheptafluorotoluene in anhydrous hydrogen fluoride.

EFFECT: improved preparing method and valuable properties of compounds.
