ONE-STEP SYNTHESIS OF METHYL t-BUTYL ETHER FROM t-BUTANOL USING PLATINUM/PALLADIUM-MODIFIED .beta.-ZEOLITE CATALYSTS (D#81,262-F) Disclosed is an improved process for preparing alkyl tertiary alkyl ethers, especially methyl t-butyl ether, in one step which comprises reacting tertiary butanol and methanol in the presence of a catalyst comprising .beta.-zeolite modified with one or more metals selected from Group VIII of the Periodic Table, and optionally further modified with a halogen or a Group IB metal, with an alumina binder, 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 MTBE-isobutylene and, optionally, diisobutylene product-rich phase and a heavier aqueous ethanol-rich phase. |
