Patent ID: 8722935

Claim:
An improved process for the conversion of isobutylene to tertiary butylamine, wherein said process comprises: a) contacting isobutylene and ammonia in the presence of a Zeolite BEA catalyst which has an Si:Al ratio in the range of 12.5:1 to 125:1 at a temperature in the range of 200-300° C. with ammonia or an ammonia, hydrogen mixture at a pressure in the range of 20-33 bar, a weight hourly space velocity (WHSV, h −1 ) in the range of 3-5, and an ammonia to isobutylene molar ratio in the range of 3-5 for a period ranging between 15-100 hrs, b) cooling the reaction mixture of step (a) to a temperature in the range of 10-30° C. and c) separating the unreacted isobutylene, ammonia and by-products from the reaction mixture as obtained in step (b) by distillation to obtain tertiary butylamine.
