C 6031 (R) ABSTRACT A process is reported for preparation of quaternary ammonium-type carbonate esters which are useful as bleach precursors in detergent compositions. The process involves transesterification of low molecular weight carbonates, e.g diphenyl carbonate, with quaternary ammonium functionalized alcohols, e.g. choline chloride. Preferably the reaction is run in a high dielectric constant aprotic solvent such as acetonitrile. The reaction may also be conducted neat utilizing liquefied carbonate reactant as a solvent medium.
