This invention relates to a process for producing ring alkylated aromatic amines. In the process an aromatic amine is reacted with an olefin using an acidic crystalline molecular sieve as a catalyst. Under the conditions of the process the catalyst is extremely active and with amines that are capable of alkylation at the ortho and para positions, high selectivity to the ortho alkylated isomer can be achieved.
本发明涉及一种生产环状烷基化芳香胺的工艺。 在该工艺中,使用酸性结晶
分子筛作为催化剂,使芳香胺与烯烃发生反应。 在该工艺的条件下,催化剂极为活跃,对于能够在正位和对位发生烷基化反应的胺,可以实现对正位烷基化异构体的高选择性。
