METHOD FOR CARBONYLATION OF ALKYL ETHERS Russian patent published in 2011 - IPC C07C67/37 C07C69/14 C07C69/03 C07C69/24 C07D305/10 C07D307/33 C07D313/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing lower alkyl ether of lower aliphatic alcohol having formula R₁-COO-R₂, involving reaction of a pre-dried lower alkyl ether having formula R₁-O-R₂, in which R₁ and R₂ independently denote C₁-C₆alkyl groups, provided that the total number of carbon atoms in groups R₁ and R₂ ranges from 2 to 12, or R₁ and R₂ together form a C₂-C₆ alkenyl group, with material which contains carbon monoxide, in the presence of a catalyst which contains mordenite and/or ferrierites in anhydrous conditions. The invention also relates to a method of producing carboxylic acids through hydrolysis of esters obtained using the method given above.

EFFECT: high output and selectivity of end product.
