1.由环氧乙烷与氨反应得到二乙醇胺，同时也得到一乙醇胺和三乙醇胺。将环氧乙烷；氨水送入反应器中，在反应温度30-40℃，反应压力70.9-304kPa下，进行缩合反应生成一；二；三乙醇胺混合液，在90-120℃下经脱水浓缩后，送入三个减压精馏塔进行减压蒸馏，按不同沸点截取馏分，则可得纯度达99%的一乙醇胺；二乙醇胺和三乙醇胺成品。在反应过程中，如加大环氧乙烷比例，则二；三乙醇胺生成比例增大，可提高二；三乙醇胺的收率。

精制方法：工业制品中含有2%以下的乙醇胺、三乙醇胺和1.5%以下的水分。精制时先进行减压蒸馏，再用水蒸气蒸馏除去乙醇胺。三乙醇胺可在其水溶液中加入氢氧化钠使成碱金属盐析出除去。最后再进行减压蒸馏精制。操作中注意防止吸收二氧化碳。
