Abstract
Process for the alkoxycarbonylation of trivinylcyclohexane.
Claims13
A process for preparing trivinylcyclohexane triesters comprising the process steps of:
- a) initially charging one of the compounds (i), (ii), (iii) or a mixture of at least two of these compounds:
- b) adding the ligand (L) and a compound comprising Pd,
- or adding a complex comprising Pd and the ligand (L):
- c) adding an alcohol having 1 to 12 carbon atoms;
- d) feeding in CO;
- e) heating the reaction mixture of a) to d), wherein the compound/the mixture of a) is converted to a trivinylcyclohexane triester.
