<p>The present invention relates to a process for the preparation of adipic acid by hydrocarboxylation of pentenoic acids. …<??>The subject of the invention is more particularly a process for the preparation of adipic acid by reaction of water and carbon monoxide with at least one pentenoic acid, in the presence of a catalyst based on rhodium and at least one iodinated promoter, at a temperature between 100 and 240 DEG C, under a pressure greater than atmospheric pressure, characterised in that … … a) the reaction is carried out in the absence of a third (additional) solvent … b) and the carbon monoxide partial pressure measured at 25 DEG C is less than or equal to 20 bar. … </p> |
