Patent

CA 2291693

The present invention provides an improved hydroformylation process in which the catalyst system is composed of a Group VIII metal and organic ligand containing phosphorous having the structure (PR2)nR' where n is an integer from 1 to 2, R and R' are organic residues which may be the same or different and where the R or R' contain at least one C9 to C40 aliphatic group positioned as a tail extending away from the primary ligand structure rendering the ligand lipophilic.

L'invention concerne un procédé amélioré d'hydroformylation dans lequel le système catalyseur est composé d'un métal du groupe VIII et d'un phosphore contenant un ligand organique présentant la structure (PR¿2?)¿n?R', dans laquelle n est le nombre entier 1 ou 2, R et R' contiennent au moins un groupe aliphatique C9 à C40 placé de manière à former une queue qui s'écarte de la structure primaire du ligand et rend ce dernier lipophile.
