METHOD FOR PURIFICATION OF MTBE-CONTAINING MIXTURES AND OBTAINING ISOBUTYLENE BY CLEAVAGE OF MTBE-CONTAINING MIXTURES

摘要

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.;16 cl, 6 dwg, 21 tbl, 8 ex
