A PROCESS FOR THE ISOMERIZATION OF A SATURATED ALIPHATIC CARBOXYLIC ACID SELECTED FROM THE GROUP CONSISTING OF ALKANOIC ACIDS OF 4 TO 18 CARBON ATOMS AND ALKANEDIOIC ACIDS OF 4 TO 12 CARBON ATOMS WHICH COMPRISES HEATING SAID CARBOXYLIC ACID WITH CARBON MONOXIDE UNDER A PRESSURE BETWEEN 20 AND 700 ATMOSPHERES AND AT A TEMPERATURE BETWEEN 250* AND 300*C. IN THE PRESENCE OF: (A) A METAL CARBONYL IN WHICH THE METAL IS SELECTED FROM THE GROUP CONSISTING OF THE METALS OF THE 6TH, 7TH AND 8TH GROUPS OF THE PERIODIC SYSTEM, (B) AM ACTIVATOR SELECTED FROM THE GROUP CONSISTING OF OXIDES, CHLORIDES, BROMIDES AND IODIES OF BISMUTH, ANTIMONY, TITANIUM, BORON, TIN AND IRON, AND (C) A HALOGEN SELECTED FROM THE GROUP CONSISTING OF CHLORINE, BROMINE AND IODINE.
