ABSTRACT:
The fractionation of the methanol- or ethanol-containing methyl-(or ethyl)-tertiary-butyl ether reactor effluent is improved by employing 2-methylpentane to azeotrope methanol or ethanol overhead, or by using 1,1,3-trichloro-1,2,2-trifluoroethane (F113) to azeotrope methanol overhead, leaving a substantially pure MTBE or ETBE bottoms.
