Title: PROCESS FOR THE CONTINUOUS CARBONYLATION OF OLEFINS
Abstract:
The invention relates to a process for the continuous carbonylation of olefins whereby an olefin is reacted with carbon monoxide and a nucleophilic compound in the presence of a catalyst system based on: (a) a source of a Group VIII metal cations, (b) a source of an aliphatic diphosphine, and (c) a carboxylic acid which is the hydrocarboxylation product of the olefin, whereby during the process the carboxylic acid is either added continuously or intermittently or is prepared in-situ by continuous or intermittent addition of water.
