Selectivity of catalytic systems RhCl3 � Polycation in hydroformylation of hex-1-ene under conditions of biphase catalysis

Abstract

Approaches to increasing the selectivity of water-soluble catalytic systems based on RhCl3 and polycation in hydroformylation of hex- 1-ene were studied. The introduction of a long-chain alkyl radical into the polycation or the use of a higher fatty acid anion results in an increase in the selectivity of the catalytic system at pH > 7 with respect to n-aldehyde to 60 %. This effect is presumably associated with the suppression of isomerization processes due to steric hindrances.
