CATALYST AND METHOD OF OBTAINING BRANCHED UNSATURATED ALDEHYDES Russian patent published in 2015 - IPC C07C47/21 C07C45/74 B01J19/24 

FIELD: chemistry.

SUBSTANCE: claimed invention relates to continuous method of obtaining branched unsaturated aldehydes, which can be used for obtaining branched alcohols or acids. method includes preparation of raw material, containing from 5 to 90 wt % of C_n aldehyde, in which n equals from 3 to 8, with raw material additionally containing from 10 to 95 wt % of solvent, interaction of raw material with resin, with resin containing acidic functional groups and not containing a metal from group VIII; reaction of mixture with resin with obtaining effluent flow, containing from 5 to 99.99 wt % of branched unsaturated C_2n aldehyde and characterised by reaction selectivity constituting not less than 92%, with formation of branched unsaturated C_2n aldehyde; removal of at least part of branched unsaturated C_2n aldehyde from effluent flow; and optionally recirculation of part of effluent flow for re-use in raw material. Invention also relates to system for claimed method realisation.

EFFECT: elaboration of continuous method of obtaining branched unsaturated aldehydes.
