摘要
采用非均相镍基催化剂催化聚醚多元醇H400和氨反应,制得端氨基聚醚D400.该反应采用固定床反应器,考察了反应温度、反应压力、空速以及氨醇摩尔比对聚醚多元醇转化率和伯胺选择性的影响.实验结果表明:在温度210 ℃、压力6.0 MPa、空速0.5h-1、氨醇摩尔比30∶1条件下,聚醚多元醇的转化率高达99.5％,伯胺选择性高达98.1％.
Abstract
The heterogeneous nickel-based catalyst was used to catalyze the reaction of polyether polyol H400 with ammonia to produce amino-terminated polyether D400.The reaction was carried out in a fixed bed reactor,and the influence of reaction temperature,reaction pressure,space velocity and molar ratio of ammonia and polyol on the conversion of polyether polyol and the selectivity of primary amine was investigated.The experimental results showed that the conversion of polyether polyol was up to 99.5％,and the selectivity of primary amine was up to 98.1％at a temperature of 210 ℃,a pressure of 6.0 MPa,a space velocity of 0.5 h-1 and a molar ratio of ammonia and polyol of 30∶1.
