Abstract
A process for the preparation of methyl formate by reacting methanol and carbon monoxide in the presence of an alkali metal alcoholate or alkaline earth metal alcoholate at from 30.degree. to 150.degree. C. and from 50 to 300 bar, wherein a nonionic complexing agent is used to bind the alkali metal cations or alkaline earth metal cations.
Claims8
A process for the preparation of methyl formate which comprises reacting methanol and carbon monoxide in the presence of sodium methylate at a temperature of 30.degree. to 150.degree. C. and a pressure of 5 to 300 bar, binding the sodium cation of said sodium methylate with a nonionic complexing agent selected from the group consisting of acyclic compounds containing a polyethylene glycol structural unit
