PROCESS FOR SEPARATING OFF ALKANOLS, MIXTURES OF ALKANOLS AND WATER OR WATER ITSELF FROM OXYGEN CONTAINING ORGANIC COMPOUNDS OF HIGHER CARBON NUMBER

摘要

Process for separating off alkanols, mixtures of alkanols and water or water itself from oxygen-containing organic compounds of higher carbon number A b s t r a c t A first alkanol having 1 to 3 C atoms or a mixture of this first alkanol with water or water itself can be separated off from oxygen-containing organic compounds having 3 to 7 C atoms from the group comprising second alkanols and dialkyl carbonates,which always have at least 2 C atoms more than the first alkanol, by permeation on membranes if a membrane obtained by plasma polymerization is employed.
