ABSTRACT:
A process for the preparation of amines by reacting an olefin with ammonia or a primary or secondary amine at a temperature of from 200 to 350.degree. C. and a pressure of from 100 to 300 bar in the presence of at least one zeolite having the specific structure type PSH-3, MCM-22 or SSZ-25, as identified by X-ray diffractogram, or mixtures of these zeolites. These specific catalysts are broadly identified as alumina zeolites and may be modified by ion exchange, doping with other metals, by dealumination to remove or replace the alumina content and by other well known after treatments such as calcination, acid-treatment and the like. Monoolefins are preferred reactants but di- and polyolefins also can be reacted with relatively high selectivity and less tendency toward polymerization.
