Abstract

A process for the production of methyl formate by carbonylation of methanol in the presence of sodium methoxide or potassium methoxide as a catalyst is improved by reduction of the catalyst consumption and intensification of the process. For this purpose, a certain amount of sodium oxaperfluoro-alkanesulfonate or potassium oxaperfluoroalkanesulfonate and up to 10% by weight of strongly organic bases are added to the mixture for carbonylation. The reaction is carried out in a reactor having a circulation pump. The sodium salts, which are reaction products of the sodium methoxide, are removed by means of a filter. The filtrate is separated with the aid of rectification and the bottom product again subjected to carbonylation. The methyl formate results as the distillate, a high yield being achieved.
