METHOD OF PRODUCING ISOBUTYLENE Russian patent published in 2011 - IPC C07C11/09 C07C1/20 B01J21/02 B01J21/18 B01J23/02

Abstract RU 2422424 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing isobutylene through decomposition of methyl-tert-butyl ether on a heterogeneous catalyst at high temperature, characterised by that the catalyst used is a calcium-boro-phosphate catalyst and the process is carried out at atmospheric pressure in the presence of water vapour with the following conditions: temperature 200-250°C, volume rate of feeding methyl-tert-butyl ether 1.0-2.0 h^-1.

EFFECT: use of the method increases conversion of methyl-tert-butyl ether in per pass.
