摘要：

研究了不同载体SAPO-11、Montmorillonite-K10、γ-Al₂O₃、ZnO和MgO负载Cu的催化剂对乙醇氨化合成乙腈反应的影响。结果表明，经还原的Cu起脱氢作用，载体不仅起分散作用而且具有协同催化的作用，其酸碱性对催化结果有显著影响，其中Cu/γ-Al₂O₃负载型催化剂具有比较理想的催化效果。在此研究基础上，考察了反应条件对Cu/γ-Al₂O₃催化剂催化性能的影响，筛选出乙醇氨化合成乙腈的适宜反应条件：反应温度290℃、反应压力0.1 MPa、乙醇重时空速1.0 h^－1、氨醇摩尔比7.0，在该条件下乙醇转化率99.7%，乙腈选择性达到92.6%。

Abstract:

The catalytic performance of SAPO-11，montmorillonite-K10，γ-Al₂O₃，ZnO and MgO loaded with Cu were studied for amination of ethanol to acetonitrile. The results showed that reduced copper metal had the function of dehydrogenation，and carriers not only played a role in the dispersion of copper metal but also had a synergistic effect. The acid-base property of carriers was closely related to catalytic results. Among these catalysts，the ideal catalytic results were obtained over the Cu/γ-Al₂O₃catalyst. The influence of reaction conditions was investigated，and the favorable conditions of amination of ethanol to acetonitrile over Cu/γ-Al₂O₃were as follows：reaction temperature of 290 ℃，reaction pressure of 0.1 MPa，ethanol WHSV of 1.0 h^－1 and ammonia/ethanol molar ratio of 7.0. The conversion of ethanol and the selectivity to acetonitrile were 99.7% and 92.6% respectively under the reaction conditions.
