Abstract
MTBE is prepared from TBA and MeOH by passing a feed mixture comprising TBA and MeOH through a primary MTBE reaction zone to form a primary reaction product containing MTBE, unreacted TBA, unreacted MeOH, isobutylene and water; the primary reaction product is fractionated to provide a first lighter distillation fraction comprising isobutylene, MeOH and MTBE and a first higher boiling distillation fraction comprising MeOH, TBA and water and the first higher boiling distillation fraction is charged to a second stage MTBE reaction zone to form a second stage reaction product comprising unreacted MeOH, unreacted TBA water, isobutylene and MTBE.
