METHOD OF THE NANOFILTRATION SEPARATION OF THE LIQUID ORGANIC MIXTURES Russian patent published in 2007 - IPC B82B3/00 

FIELD: food industry; chemical industry; pharmaceutical industry; petrochemical industry; oil processing industry; method of the nanofiltration separations of the liquid organic mixtures. SUBSTANCE: the invention is pertaining to the method of the nanofiltration separations of the liquid organic mixtures, in particular, to separation of the large molecules of the organic substances with the a molecular mass above 600 Dalton from the organic solvents, and may be used in alimentary, chemical, pharmaceutical, petrochemical and oil processing industries. The method of the nanofiltration separations of the liquid organic mixtures, in particular, the large organic moleculas with the molecular mass above 600 Dalton from organic solvents by their pressing through the diaphragm, with the preliminary preparation of the diaphragm, they use the planar solid diaphragm made in the form of the monolithic film, the material for which is polytrimethylsilylpropyne (PTMSP). Preliminary they conduct preparation of the diaphragm by saturation of the dry diaphragm with the dissolvent of the same name. As the dissolvent may be used_; for example, alcohols and ketones. The technical result of the invention is development of the method of the nanofiltration separation ensuring the high permeability of the dissolvents with the simultaneous keeping of the volumetric organic compounds.

EFFECT: the invention ensures development of the method of the nanofiltration separation providing the high permeability of the dissolvents with the simultaneous keeping of the volumetric organic compounds.
