Abstract

Method for producing a dehydrated liquid mixture comprising water in an amount of less than 20 ppm, for use as a solvent for a conducting salt, comprising or consisting of the following steps: —providing or preparing a liquid starting mixture comprising—a total amount of 90% by weight or more, based on the total amount of the liquid starting mixture, of compounds selected from the group of organic carbonates, acetic acid esters of C1 to C8 alcohols and butyric acid esters of C1 to C8 alcohols, wherein the total amount of acetic acid esters of C1 to C8 alcohols and butyric acid esters of C1 to C8 alcohols is in the range of from 0 to 45% by weight, based on the total amount of the liquid starting mixture, —water in a total amount of 3500 ppm to 20 ppm, based on the total amount of the liquid starting mixture, —optionally further constituents, —contacting the liquid starting mixture with an amount of a binderless zeolite molecular sieve such that the water content in the mixture is reduced to an amount of less than 20 ppm, based on the total amount of the dehydrated liquid mixture.
