METHOD FOR CARBONYLATION OF ALIPHATIC ALCOHOLS AND/OR REACTIVE DERIVATIVES THEREOF Russian patent published in 2012 - IPC C07C53/08 B01J29/70 C07C51/09 C07C51/12 C07C67/36 C07C67/37 C07C69/14 

FIELD: chemistry.

SUBSTANCE: invention relates to an improved method of producing C₁-C₃ aliphatic carboxylic acid and/or the corresponding ester, by carbonylating the corresponding C₁-C₃ aliphatic alcohol and/or an ester or ether derivative thereof with carbon monoxide material containing hydrogen, in the presence of a catalyst containing a zeolite having at least one 8-member ring channel, said 8-member ring channel being connected with a channel formed by a ring with greater than or equal to 8 members, said 8-member ring having a window size of at least 2.5 Å × at least 3.6 Å and at least one Bronsted acid site and that zeolite has a silicon dioxide: X₂O₃ molar ratio of not less than 5, where X is selected from aluminium, boron, iron, gallium and mixtures thereof with the condition that the zeolite is not mordenite or ferrierite. The catalysts demonstrate considerable carbonylation activity compared to other zeolite catalysts.

EFFECT: improved method of producing C₁-C₃ aliphatic carboxylic acid.
