Abstract 1. AN IMPROVED ALKANE ISOMERIZATION PROCESS WHICH COMPRISES ISOMEERIZING NORMAL PARAFFINS HAVING FROM 4 TO 8, INCLUSIVE CARBON ATOMS TO SKELETAL ISOMERS CONTAINING THE SAME NUMBER OF CARBON ATOMS BY CONTACTING THE PARAFFINS UNDER ISOMERIZATION CONDITIONS WITH A LIQUID PHASE CATALYST SELECTED FROM THE GROUP CONSISTING OF ARSENIC PENTAFLUORIDE, ANTIMONY PENTAFLUORIDE, AND MIXTURES THEREOF WITH EITHER TRIFLUOROMETHANESULFONIC ACID OR HDROGEN IN THE PRESENCE OF SUFFICIENT HYDROGEN TO PROVIDE A HYDROGEN PARTIAL PRESSURE OF 900-4000 P.S.I.G. DURING SAID ISOMERIZATION TO SUPPRESS CRACKING OF PARAFFINIC REACTANTS TO LESS DESIRABLE CRACKED PRODUCTS AND INCREASE SELECTIVELY TO DRSIRED ISOMERIC PRODUCTS.
