【摘要】 以磷酸氢镊为催化剂，水为稀释剂，采用乙醇胺、二乙醇胺等摩尔进料，在管式反应器内合成三乙烯二胺，得到其适宜的工艺条件。转化率、选择性分别可达３５％～５１％、６０％～７１％。更多还原

【Abstract】 Abstract Favourable process conditions are sug-gested by researching on the synthesis processof triethylenediamine（TEDA）in this paper. The TEDA was synthesized in the tubereactorby the reaction of ethanolamine with di-ethanolamine in equal mole quantity,SrHPO₄and H₂O were used as a catalyst and a diluentrespectively. The conversion and selectivityreached 35%～51%and 60%～71%respec-tively.更多还原
