REGULATION OF RATIO ALDEHYDE OF NORMAL STRUCTURE: ALDEHYDE OF ISO-STRUCTURE IN PROCESS OF HYDROFORMYLATION WITH MIXED LIGAND BY REGULATION OF SYNTHESIS-GAS PARTIAL PRESSURE Russian patent published in 2015 - IPC C07C47/02 C07C45/50 

FIELD: chemistry.

SUBSTANCE: invention relates to method of regulating hydroformylation process for obtaining aldehydes of normal structure (N) and iso-structure (I) with ratio N:I. Claimed method includes contact of unsaturated olefin compound with synthesis-gas and catalyst, which contains transition metal and organopolyphosphite and organomonophosphite ligand, with contact being carried out in conditions of hydroformylation, including partial pressure of synthesis-gas, where method includes increase of partial pressure of synthesis-gas to reduce ratio N:I or reduction of partial pressure of synthesis-gas to increase ratio N:I.

EFFECT: obtaining aldehydes of normal structure (N) and iso-structure (I) with ratio N to I.
