A method for the preparation of methyl - t - butyl ether and these ether group-containing fuel mixture

摘要

A method for producing methyl tert-butyl ether which comprises the steps of: allowing isobutylene-containing hydrocarbon and methyl alcohol in a given molar ratio to react at a given temperature, pressure and liquid space velocity in the presence of strongly acidic cation- exchange resin catalyst; then passing the reaction product through a fixed bed filled with a water-insoluble, solid particulate acid- neutralizing agent; and subjecting the effluent to flashing operation, preferably also to rectification, to obtain methyl tert-butyl ether. Further included in the invention is the preparation of a fuel composition by mixing the thus obtained methyl tert-butyl ether into an internal combustion fuel.
