Abstract: of the disclosure: A process for the preparation of pourable choline chloride/silica powders by mixing silica with choline chloride and, where appropriate, drying this mixture, wherein spray-dried or fluidized beddried silica which has a particle size of from 30 to 250 .mu.m is mixed with an aqueous choline chloride solution which contains from 70 to 80% by weight, based on the solution, of choline chloride and is at from 40 to 80.degree.C, thereafter from 0.05 to 0.4% by weight, based on the mixture, of magnesium stearate or calcium stearate is added and, if appropriate the resulting mixture is dried.

Date Apr. 18, 1996A method of separating heteropoly compounds from mixtures of polyethers, polyesters and/or polyether esters, a protic component and heteropoly compounds, wherein the protic component is removed from the mixture and subsequently separating off the heteropoly compound as a separate phase. The polymer phase which remains is preferably brought into further contact with a solid adsorbent that is capable of adsorbing heteropoly compounds.
