A PROCESS FOR SHIFTING A DOUBLE BOND OF AN OLEFINIC HYDROCARBON OF MORE THAN THREE CARBON ATOMS PER MOLECULE TO A MORE CENTRALLY LOCATED POSITION IN THE HYDROCARBON MOLECULE, WHICH CONSISTS ESSENTIALLY OF ISOMERIZING SAID OLEFINIC HYDROCARBON IN CONTACT WITH A PREFORMED COMBINED BORON TRIFLUORIDE-ZIRCONIA CATLYST PREPARED BY TREATING SUBSTANTIALLY ANHYDROUS ZIRCONIA WITH BORON TRIFLUORIDE AT A TEMPERATURE OF FROM ABOUT 50*C. TO ABOUT 250*C UNTIL BORON TRIFLUORIDE NO LONGER COMBINES WITH THE ZIRCONIA.
