FIELD: petroleum chemistry.
SUBSTANCE: isobutene containing C4-hydrocarbon stream is brought into contact with methanol onto acid catalyst in one or more reactors to obtain equilibrium in relation to methyl-tert-butyl ester following by interaction of remaining in mixture isobutene in reactive distillation column filled with acid ion-exchange resin. Reactive distillation column is operated under pressure of 3-15 bar (abs.) at temperature in reaction zone of 55°C-75°C and reflux-to-product ratio less than 1.
EFFECT: target products of improved quality.
