METHOD OF CARBONYLATION Russian patent published in 2015 - IPC C07C51/12 C07C67/37 C07C27/00 C07C53/08 C07C69/14 B01J29/18 

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining at least one product of carbonylation, selected from the group, including acetic acid and methylacetate, which includes carbonylation of at least one carbonylatable reagent, selected from the group, including methanol and its reaction-able derivatives, with carbon monoxide in presence of catalyst, where said catalyst is represented by mordenite, possessing molar ration silicon dioxide: X₂O₃ (where X stands for Al and/or Ga), constituting not less than 12:1; and additionally, where said mordenite is processed according to single-staged technique with basic water solution, containing at least one of the following: aluminate-ions and gallate-ions, or is successively processed with separate water solutions (a) of base and (b) aluminate- and/or of gallate-ions or their source.

EFFECT: invention relates to application of catalysts, represented by said mordenite, in method of obtaining at least one carbonylation product, selected from the group, including acetic acid and methylacetate, with provision of improved catalytic activity.
