铜基催化剂的制备及其催化苯胺N-甲基性能

Preparation of Copper-based Catalyst and Its Catalysis Performance in Aniline N-methylation

N-甲基苯胺(NMA)广泛应用于化工生产中,以苯胺和甲醇为原料,采用气相法合成NMA,研究的重点在于提高CuO/ZnO/Al_2O_3催化剂的稳定性。通过分析CuO/ZnO/Al_2O_3催化剂的制备条件及助剂的作用,为合成优良催化性能的催化剂提供理论指导。

N-methyl aniline（NMA） is widely used in chemical production. NMA is always synthesized from aniline and methanol by vapor phase method, the focus of the study is to improve the stability of CuO/ZnO/Al_2O_3 catalyst. In this paper, the preparation conditions and additives of CuO/ZnO/Al_2O_3 catalyst were analyzed.
