Abstract
This invention relates to an improvement in a process for the production of an alkyl formamide, wherein a gas-containing carbon monoxide is reacted at elevated temperature and pressure in reaction zone with a nitrogen-containing compound selected from the group consisting of ammonia, a primary or secondary alkylamine, in the presence of a solvent and a catalyst. The improvement comprises utilizing a solvent comprising a polyethylene glycol, polypropylene glycol, polyethylenepropylene glycol, or mixtures, and an alkali metal or alkaline earth metal alkoxide of a polyethylene glycol, polypropylene glycol, polyethylenepropylene glycol or mixtures as the catalyst.
