Process for the continuous separation and concentration of butanol from dilute aqueous-organic medium

摘要

A continuous process for isolating and concentrating the butanol from dilute aqueous organic media by a combination of purge carrier gas and discharge through the membrane, characterized in that the first carry purge liquid phase of the carrier gas, and then - the allocation of butanol through the membrane, selective for the target component, as whose material is poly (4-methyl-2-pentyne) general formula, where the number of links in the chain n = 1200-23000, the molecular mass M = 100800-1900000, prepared from 4-methyl-2-pentyne in the presence NbCl- EtSiH, and further impl stvlyayut recycle carrier gas into the reservoir initial liquid mixture.
