摘要

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).
