Method of separating alcohols, alcohol/water mixture or water from oxygen containing organic compound

摘要

A first alkanol having 1 to 3 C atoms or a mixture of this first alkanol with water or water alone can be separated off by membrane permeation from oxygen-containing organic compounds having 3 to 7 C atoms selected from the group comprising second alkanols and dialkyl carbonates which always have at least 2 C atoms more than the first alkanol, if a membrane is used which is obtained by plasma polymerisation.
