FIELD: process engineering.
SUBSTANCE: invention relates to chemistry, namely, to separation of liquid mixes and may be used in various industries and agriculture. Proposed method consists in thermal-gradient pervaporation separation of liquid mixes through target component-selective membrane via collection of permeate vapor by condensation on solid surface with temperature lower than that of separated mix. Membrane material represents the composition consisting of poly(1-trimethylsilyl-1-methyl acetylene) with the number of links in the chain n=900-25000 and molecular mass MM=100000-2800000 and polydimethalsimethylene with the number of links of the chain n=1200-17000 and molecular mass MM=86000-1200000. Note here that content of polydimethalsimethylene in said composition makes 1.0-12.0 wt %.
EFFECT: higher efficiency of separation, preventing problems of ecology.
