Abstract: A PROCESS IS DISCLOSED FOR DISPROPORTIONATING AN OLEFIN HAVING FROM 3 TO 30 CARBON ATOMS, WHEREIN THE OLEFIN IS CONTACTED WITH A CATALYST CONSISTING ESSENTIALLY OF AN OXIDE OF TUNGSTEN AND COPPER OR OF TUNGSTEN AND A METAL OF THE 8TH GROUP OF THE PERIODIC SYSTEM, PREFERABLY IRON, COBALT OR BICKEL, IN WHICH THE RATIO OF METAL TO TUNGSTEN IS IN THE RANGE OF 1:3 TO 5:1. THE CATALYST IS ADVANTAGEOUSLY SUPPORTED BY A CARRIER SUCH AS SILICA AND ITS CONTACT WITH THE OLEFIN IS EFFECTED AT A TEMPERATURE IN THE RANGE OF 400 TO 700*C, AT A PRESSURE IN THE RANGE OF 1 TO 50 ATMOSPHERES AND FOR A CONTACT TIME IN THE RANGE OF 0.1 TO 60 SECONDS.
