METHOD OF OBTAINING BENZYLBUTYL ETHER Russian patent published in 2014 - IPC C07C43/164 C07C41/09

Abstract RU 2536486 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of obtaining benzylbutyl ether, which serves as a flavour for food products. The method consists in intermolecular dehydration of benzyl alcohol and n-butanol in the presence of a catalyst - copper (II) bromide CuBr₂ at a temperature of 140-175°C for 2-10 h with a molar ratio of [CuBr₂]:[BnOH]:[H-C₄H₉OH]=1-5:100:100-400.

EFFECT: method makes it possible to selectively obtain the target product with the high output with the application of an available and cheap catalyst.
