METHOD OF SYNTHESIS OF METHYL-TERT-BUTYL ESTER Russian patent published in 1998 - IPC

Abstract RU 2104993 C1

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to synthesis of high-octane antidenotation additions to engine fuel and trimethylcarbinol used for isobutylene producing. Method involves interaction of isobutylene fractions isobutylene with methanol as concentrated an aqueous solution of methanol containing 5-10 wt.-% water on sulfocation-exchange resin in -form at parallel feeding fraction at 20-100 C in tube or reaction-fractionating reactors. Crude methanol containing 0.05-0.15 wt. -% dimethyl ether can be used as methanol concentrated an aqueous solutions. Method can be used in petrochemical industry. EFFECT: improved method of synthesis. 3 cl, 3 tbl, 1 dwg
