A process for preparing ethyl t-butyl ether in one step which comprises reacting tertiary butanol and ethanol in the presence of a catalyst selected from beta -zeolite and beta -zeolite modified with multimetals selected from the group consisting of Groups IB, VB, VIB, VIIB or VIII of the Periodic Table at a temperature of 20 DEG C to 250 DEG C and 0.1 to 7.0 MPa. The product comprises a two-phase mix of an ETBE-isobutylene and, optionally, diisobutylene product-rich phase and a heavier aqueous ethanol-rich phase. |
