METHOD OF NANOFILTRATION OF LIQUID ORGANIC MIXES |
摘要 |
FIELD: process engineering. ^ SUBSTANCE: invention relates to nanofiltration of liquid organic mixes. Proposed method comprises squeezing said mixes through membrane based on poly[1-(trimethylsilyl)-1-methyl acetylene] wherein solutions of compounds with molecular weight over 300 g/mol in solvents are used while membrane is pre-modified on anode at constant current discharge and alcohols or ketones are used as solvents. Said nanofilter allows retention of larger organic molecules for poly[1-(trimethylsilyl)-1-methyl acetylene]-membrabes exceeds (98%) that for initial modified poly[1-(trimethylsilyl)-1-methyl acetylene]-based membranes (95%). ^ EFFECT: higher separation efficiency. ^ 2 cl, 2 tbl, 4 ex |
