Abstract
The invention relates to a process for reaction of a carbonylatable compound using a metal complex catalyst comprising a metal of transition group VIII and an organophosphorus ligand and in the presence of a stabilizer based on a sterically hindered secondary amine.
Claims21
A carbonylation process in which at least one compound which is capable of being carbonylated by a carbon monoxide is reacted with the carbon monoxide in the presence of a metal complex catalyst of a metal of transition group VIII of the Periodic Table of the Elements which has an organophosphorus compound as ligand, wherein the carbonylation is carried out in the presence of a sterically hindered secondary amine having the general structural formula I
- where Ra, Rb, Rc, Rd, Re and Rf are identical or different hydrocarbon radicals which may be joined to one another.
A mixture comprising a metal complex catalyst of a metal of transition group VIII of the Periodic Table of the Elements which has an organophosphorus compound as a ligand and a sterically hindered secondary amine having the formula I,
- where Ra, Rb, Rc, Rd, Re and Rf are identical or different hydrocarbon radicals which may be joined to one another.
