Abstract
The invention discloses an improved process for the conversion of isobutylene to tertiary butylamine with conversion up to 50% at pressure lower than 40 bar.
Claims6
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 catalyst at a temperature in the range of 200-300° C. with ammonia or ammonia, hydrogen mixture pressure in the range of 20-33 bar, weight hourly space velocity (WHSV, h−1) in the range of 3-5, 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 reaction mixture as obtained in step (b) by distillation to obtain tert-butyl amine.
