Abstract:
A process for preparing a carboxylic acid by the carbonylation of an alcohol in a reaction medium is provided. The reaction medium includes a catalyst promoter having a metal species selected form the group consisting of group IIIA-IVA metals, group IB-VIIIB metals and lanthanides, together with a hydrohalic acid to prevent catalyst precipitation and to maintain high reaction rates in case of low water content.
