METHOD OF CARBONYLATION Russian patent published in 2014 - IPC C07C51/12 C07C67/37 C07C27/00 C07C53/08 C07C69/14 B01J29/18 

FIELD: chemistry.

SUBSTANCE: invention relates to an improved method of obtaining at least one product of carbonylation, selected from a group, including acetic acid and methylacetate, which includes carbonylation of at least one carbonylatable reagent, selected from a group, which includes methanol and its reactionable derivatives, with carbon monoxide in the presence of a catalyst, where the said catalyst is represented by mordenite, processed with a water solution of ammonium hydroxide and possessing a molar ratio silicon dioxide:aluminium oxide, constituting not less than 10:1. The invention also relates to an application of the catalyst, represented by mordenite, possessing a ratio silicon dioxide:aluminium oxide, constituting not less than 10:1, processed with a water solution of ammonium hydroxide, with provision of an improved catalytic activity in the said method.

EFFECT: improvement of the method of obtaining at least one product of carbonylation.
