N,N-二甲基乙二胺制备

投料比（质量）盐酸2-氯乙胺：40%二甲胺：片碱：助滤剂：片碱=1：3.88：1.85：0.22：0.08。

将10%二甲胺水溶液加到搪玻璃反应釜中，搅拌下冷却至15℃，并在0.5~1h内分批加入盐酸2-氯乙胺，温度不超过20℃。加毕，让反应液自然升温至37℃。然后慢慢冷却至30℃，停止冷却，再让料液继续自然升温至38℃，接着又将料液冷却至30℃，再升温至62℃，尾气放出的氯化氢则用水或碱吸收。反应混合物在62~65℃下搅拌3h后，冷却至20℃，并在0.5~1h内分批加入片碱，料液温度控制在（25±5）℃。加完片碱后，继续在（25±5）℃下搅拌1h，再静置分层。然后分出有机层，水层则为乳状液，需加入硅藻土进行过滤，所得的滤液澄清后再分层。然后合并有机层，加入片碱干燥，并过滤。滤液去蒸馏，先回收未反应的二甲胺，最后收集104~106℃的馏分，即N,N-二甲基乙二胺。含量大于97%，收率大于75%。
