This patent describes a continuous process for converting crude methanol to methyl tertiary-alkyl ethers and gasoline. It comprises contacting a crude methanolic feedstock containing a minor amount of water with a liquid olefinic hydrocarbon extraction solvent stream rich in C{sub 4}{sup +} iso-alkene hydrocarbon under extraction conditions favorable to selective extraction of the methanol, thereby providing a non-aqueous organic extract liquid stream rich in methanol and an aqueous raffinate stream containing unextracted methanol; charging liquid hydrocarbon extractant and extracted methanol substantially free of water to a first etherification catalytic reaction zone for contact with acid etherification catalyst under etherification process conditions for converting methanol and iso-alkene hydrocarbon to predominantly methyl tertiary-alkyl ether.
