大连已经开发出国产十二醇直接胺化法生产N,N——二甲基烷基(十二烷基)叔胺高活性(醇转化率99％)高选择性(叔胺收率94—95％)工业催化剂。发现载体的SiO_2/Al_2O_3对催化剂的活性、选择性有明显影响,并初步讨论了这一发现,并提出了催化剂载体表面的Al_2O_3与负载NiO之间的相互作用可能影响活性中心形成的观点。
Dalian has developed a domestic direct production of dodecanol N, N - dimethyl alkyl (dodecyl) tertiary amine high activity (alcohol conversion rate of 99%) high selectivity (tertiary amine yield 94- 95%) industrial catalyst. The results indicate that the interaction between Al 2 O 3 and NiO on the surface of catalyst supports may affect the formation of active sites.
