Method of Producing Carboxylic Acids by Carbonylation of Olefins |
| abstract |
The present invention relates to a process for preparing carboxylic acids based on olefins and carbon monoxide in the presence of water. The process of the present invention is a catalyst system that does not contain halogens: a) rhodium or rhodium compounds, b) at least one nitrogen-containing heterocyclic compound, c) at least one alkali metal of aliphatic C 2 -C 20 -carboxylic acid Salts or alkaline earth metal salts and d) mixtures of at least one glycol ether of the formula (I).n n n <Formula I>n n n n n n n n Wherein R 1 and R 2 are independently C 1 -C 20 -alkyl or R 3 CO, wherein R 3 is hydrogen or C 1 -C 20 -alkyl, or R 1 and R 2 together are C 1 -C Forms a 20 -alkylene chain, n is 1 to 30; |
