FIELD: process engineering.
SUBSTANCE: invention relates to chemistry, particularly, to separation of fluid mixes and may be used in various industrial branches and agriculture. This method exploits thermal gradient pervaporation separation of fluid mixes in target component-selective membrane by accumulating permeate vapors by condensation on solid surface with its temperature is lower than that of separated mix wherein membrane material represents poly(1-trimethylsilyl-1- methyl acetylene) of general formula 
, where n is the number of links in chain, of molecular mass MM=100800-1900000, while extraction and concentration of organic substances is performed at atmospheric pressure.
EFFECT: simplified and relatively cheap procedure.
