METHOD OF PRODUCING ISOBUTYLENE Russian patent published in 2019 - IPC C07C11/09 C07C1/20

Abstract RU 2691076 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing isobutylene by decomposing methyl-tertiary-butyl ether (MTBE) on a heterogeneous aluminosilicate catalyst at high temperature in the presence of water vapour. Catalyst used is industrial aluminium silicate catalysts K-84 or K-97 or K-15. Process is carried out at temperature of 200–300 °C ratio H₂O:MTBE = 1.0–3.0 and MTBE volumetric feed rate of 0.5–1.0 h^-1.

EFFECT: disclosed method reduces the amount of dimethyl ether impurities and the cost of preparing the catalyst.
