摘要
研究了从单乙醇胺 (MEA)和氨合成乙撑胺。所用的催化剂为 ZSM- 5分子筛。反应条件为 :t=2 80～ 3 6 0°C,p=2 .0～ 8.0 MPa,NH3/MEA=5～ 5 0 (摩尔比 )。反应对 EDA、PIP、TEDA的选择性较高 ,MEA的转化率可达到 85 %。
The synthesis of ethylenediamines (EDA) from monoethanolamine (MEA) and ammonia was investigated. The use of ZSM-5 zeolite as catalyst was studied. The reaction was carried out at: t=280~360°C, p=2.0~8.0 MPa, NH 3/MEA=5~50(mol ratio). This reaction showed high selectivity for EDA, PIP, TEDA. The conversion of MEA reached 85%.
