ONE-STEP SYNTHESIS OF ETHYL t-BUTYL ETHER FROM t-BUTANOL USING .beta.-ZEOLITE AND MULTIMETAL-MODIFIED .beta.-ZEOLITE CATALYSTS (D#81,264-F) Disclosed is an improved 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 zeolite beta and zeolite beta modified with multimetals selected from the group consisting of Groups IB, VB, VIB, VIIB or VIII of the Periodic Table at a temperature of about 20.degree.C to 250.degree.C and atmospheric pressure to about 1000 psig, wherein when the temperature is in the operating range above about 140.degree.C, the product comprises a two-phase mix of an ETBE-isobutylene and, optionally, diisobutylene product-rich phase and a heavier aqueous ethanol-rich phase. |
