METHOD OF PRODUCING CARBONYLATION PRODUCTS Russian patent published in 2012 - IPC C07C51/12 B01J29/18 B01J29/22 B01J29/24 B01J29/26 B01J37/02 B01J37/08 C07C53/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a novel catalyst for use in synthesis of aliphatic carboxylic acid containing (n+1) carbon atoms, where n denotes an integer of up to 6, and/or an ether derivative thereof by bringing an aliphatic alcohol containing n carbon atoms, and/or reactive derivative thereof, selected from dialkyl ether, ester of alcohol and alkyl halide, into contact with carbon monoxide, where said catalyst is prepared via ion exchange or saturation of the ammonium or hydrogen form of mordenite with silver, drying the saturated/ion exchange-treated mordenite and subsequent calcination of the dried silver-containing mordenite at temperature from 500 to 600°C. The invention also relates to a method of producing aliphatic carboxylic acid containing (n+1) carbon atoms, where n denotes an integer of up to 6, and/or an ether derivative thereof, which involves bringing the aliphatic alcohol containing n carbon atoms and/or reactive derivative thereof, selected from dialkyl ether, ester of alcohol and alkyl halide, into contact with carbon monoxide in the presence of said catalyst.

EFFECT: improved selectivity with respect to carbonylation products.
