The invention relates to a method for the manufacture of N,N-dialkyllactamide, whereby at least one of the compounds selected from the series consisting of alkyl lactate, lactide and polylactic acid is mixed with dialkylamine in order to form a reaction mixture, under conditions whereby aminolysis takes place in the reaction mixture. The method is characterized in that the reaction mixture further comprises a Lewis acid. As a result of the invented method, N,N-dialkyllactamides can be manufactured in high yields and with high optical purity.
本发明涉及一种制备N,N-二烷基内酰胺的方法,其中从由烷基乳酸酯、乳酸内酯和聚乳酸组成的系列中至少选择一种化合物与二烷基胺混合,以形成反应混合物,在反应混合物中进行胺解反应。该方法的特征在于,反应混合物还包括一种路易斯酸。由于该发明方法,N,N-二烷基内酰胺可以高产率、高光学纯度地制备。
