ABSTRACT:
A process for stabilizing aqueous solutions of acetoacetamides which simultaneously results in the reduction of .beta.-aminocrotonic acid amide content. According to the process, to aqueous acetoacetamide solutions which have been prepared in a known manner by the reaction of diketene with ammonia or water-soluble primary or secondary aliphatic amines under basic conditions, sufficient amounts of diketene are added immediately after their preparation thereto at room temperature with vigorous stirring, to maintain a pH value of 6-7. The so obtained aqueous solutions of the acetoacetamides are not only substantially stable, but also especially pure since these solutions are neither contaminated by salt-like by-products nor by derivatives of .beta.-aminocrotonic acid amides.
