FIELD: chemistry.
SUBSTANCE: invention relates to method for purification of technical methyl-tert-butyl ether (MTBE). Method includes the following stages: a) preparation of technical MTBE (I), containing at least MTBE, methanol, C4-hydrocarbons, C5-hydrocarbons and acetone, b) distillation separation of technical MTBE (I) into main product (II), containing C4- and C5-hydrocarbons, side flow (III), containing acetone, methanol and MTBE and MTBE-containing bottom product (IV).
EFFECT: claimed method makes it possible to obtain highly pure MTBE.
