| titleOfInvention | Membrane for concentrating aqueous solution of volatile organic liquid and its production |
| abstract | PURPOSE:To produce the membrane for concentrating an aq. soln. of a volatile org. liq. with the permeability and permselectivity improved by forming the membrane from a soln. of polyvinylidene fluoride-based polymer in a mixture of a solvent for the polymer and a solvent having higher volatility than the polymer solvent. CONSTITUTION:The membrane is formed from the soln. of a polyvinylidene fluoride-based polymer contg. at least 50wt.% polyvinylidene polymer in a mixture of the polymer solvent (e.g. dimethylformamide) and a solvent (e.g. toluene) having higher volatility than the polymer solvent. The ratio of the polymer solvent to the high-volatility solvent is controlled to 0.05-20wt.% based on the total solvent weight. Consequently, the volatile org. liq. is selectively separated from the aq. soln. and concentrated, and a membrane for concentrating an aq. soln. of a volatile org. liq. capable of being used in the liq.-liq. membrane separation method and with the permeability and permselectivity improved is produced. |
