Abstract: The present invention provides a process for preparing polyoxyalkylene glycols of a certain molecular weight in one stage by copolymerizing tetrahydrofuran and alpha,omega-diols as the comonomer in the presence of a heteropolyacid and of a hydrocarbon, by distilling off a mixture of water and this hydrocarbon from the copolymerization, which comprises terminating the polymerization when this molecular weight is attained by adding water, comonomer, butanediol or butanediol-water mixtures.

Abstract: Single-step preparation of quaternary ammonium hydroxide (I) comprises conversion of quaternary ammonium formates (IIa) or quaternary ammonium carbonates (IIb) into (I) in the presence of a solvent and a catalyst, which is at least a metal of the groups 8-12 of the periodic system of the elements. Independent claims are included for: (1) (I) obtained by the method; and (2) use of metal of the Group 8-12 of the periodic system of element for preparing (I).
