ABSTRACT:
Disclosed is a process for preparing alkyl tertiary alkyl ethers in one step which comprises reacting tert-butanol and a C.sub.1 -C.sub.4 primary alcohol in the presence of a catalyst consisting essentially of a pentasil zeolite having a silica/alumina ratio of 50-150, optionally with a binder at a temperature of about 80.degree. to 200.degree. C. and atmospheric pressure to about 1000 psig, wherein when the temperature is in the operating range above 140.degree. C., the product comprises a two-phase mix of a MTBE or ETBE and isobutylene product-rich phase and a heavier aqueous primary alcohol-rich phase.
