PROCESS FOR PREPARING METHYL TERT-BUTYL ETHER Russian patent published in 1996 - IPC

Abstract RU 2063397 C1

FIELD: high octane additive to motor fuels. SUBSTANCE: product: methyl tert-butyl ether (MTBE). Reagent 1: isobutylene- containing fraction. Reagent 2: methanol. Reaction conditions: isobutylene to methanol molar ratio is 0.90- 0.99:1. Catalyst is sulfocationite in H-form, two reaction zones, methanol is fed to first reaction zone and process is carried out to 95-99% conversion at temperatures form 20-40 to 80-110 C, the resulting MTBE is separated in rectification column and the unreacted compounds are fed to second zone where process is carried out at temperatures from 20-30 to 40-58 C. EFFECT: improved properties of the title compound. 1 dwg
