METHOD OF PROCESSING BUTANOL-BUTYL FORMATE FRACTION Russian patent published in 2012 - IPC C07C31/12 C07C29/141 C07C45/50 B01J21/18 B01J27/02 B01J23/06

Abstract RU 2454392 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of processing a butanol-butyl formate fraction, relating to by-products of the propylene hydroformylation process. The method involves splitting butyl formates at temperature 220-260°C, pressure 1.5-10 atm, volume rate of feeding raw material and hydrogen of 0.2-0.5 h^-1 and 360-2150 h^-1, respectively, to obtain butanols and carbon monoxide as end products. The process is carried out on a catalyst having the following composition, wt %: zinc oxide - not less than 98.0, sulphur - not more than 0.3, carbon - the balance.

EFFECT: method enables to obtain end products (butanols) with high output and selectivity with high conversion of butyl formates.
