Abstract
Methyl tertiary butyl ether and diisobutylene are prepared by reacting methanol with tertiary butyl alcohol to provide an etherification reaction product containing methyl tertiary butyl ether, tertiary butyl alcohol, methanol, isobutylene, and water. A methyl tertiary butyl ether product fraction and an isobutylene fraction are recovered from the etherification reaction product; the isobutylene fraction is charged to an isobutylene conversion reaction zone to form a diisobutylene conversion product, and the diisobutylene conversion product is charged to a diisobutylene distillation zone and separated therein into a lower boiling distillation fraction comprising isobutylene, and diisobutylene and a higher boiling distillation fraction consisting essentially of diisobutylene.
