Abstract

The present invention is for a process for the preparation of alkali metal salts of acyl cyanamides, especially those of aliphatic carboxylic acids by reacting carboxylic acid esters of lower alcohols with monoalkali metal cyanamides. The reaction results in a process which is simple and efficient and one which can be used in commercial scale batch or continuous operations.
