| 摘 要： | 研究以HZP-II催化剂、异丁烯和液氨为原料，选择了直接胺化制备叔丁胺的工艺路线，考察了空速、氨烯比、压力、温度对反应转化率的影响，并对催化剂使用寿命进行了稳定性评价。实验结果表明，在反应压力5 MPa、反应温度260 ℃、异丁烯空速450 h―1、氨烯比（1.5～3.0）∶1时，反应2000 h以上，异丁烯单程转化率仍能保持10.2%，产物叔丁胺的选择性>99%。

| Abstract: | The environment-friendly preparation process of tert-butylamine by reacting isobutene with ammonia over HZP-II catalyst was studied. The affecting factors on amination were investigated，such as space velocity，reaction temperature，ratio of ammonia to isobutene. In addition，the life of HZP-II catalyst was assessed. Under optimal conditions: reaction pressure 5MPa，reaction temperature 260 ℃，isobutene space velocity 450 h－1，mole ratio of ammonia to isobutene (1.5—3.0)∶1，reaction time more than 2000h，conversion of isobutene and selectivity of tert-butylamine could be up to 10.2% and 99% respectively. |
