  The present invention pertains to a process for manufacturing dialkyl lactamide comprising the steps of reacting lactide and dialkylamine selected from one or more of dimethylamine, diethylamine, and methylethylamine to form a reaction mixture which comprises dialkyl lactamide selected from N, N-dimethyl lactamide, N,N-diethyl lactamide, and N,N-methylethyl lactamide, N,N-dialkyl lactoyl lactamide, and dialkylamine, subjecting the reaction mixture to a separation step to form a product stream comprising N,N-dialkyl lactamide, a first recycle stream comprising dialkylamine and a second recycle stream comprising N,N-dialkyl lactoyl lactamide, feeding the recycle streams to the reaction step, and isolating the product stream. The process allows the manufacture of N, N-dimethyl lactamide, N,N-diethyl lactamide, and N,N-methylethyl lactamide on commercial scale.

  本发明涉及一种制造二烷基内酰胺的方法，包括以下步骤：将内酯和二烷基胺（所选自二甲胺、二乙胺和甲乙胺）反应，形成反应混合物，其中包括所选自N，N-二甲基内酰胺、N，N-二乙基内酰胺、N，N-甲乙基内酰胺、N，N-二烷基内酰基内酰胺和二烷基胺的二烷基内酰胺；将反应混合物经过分离步骤，形成产品流，其中包括N，N-二烷基内酰胺、第一循环流，包括二烷基胺和第二循环流，包括N，N-二烷基内酰基内酰胺；将循环流送回反应步骤，隔离产品流。该方法允许商业化生产N，N-二甲基内酰胺、N，N-二乙基内酰胺和N，N-甲乙基内酰胺。
