Process for separating off alkanols, mixtures of alkanols and water or water itself from oxygen-containing organic compounds of higher carbon number
Process for separating off alkanols, mixtures of alkanols and water or water itself from oxygen-containing organic compounds of higher carbon number
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.
