1. A study has been made of the contact-catalysis reactions of hexane, heptane, and octane in presence of platinized alumina at 460° under a high pressure of hydrogen (15-20 atm). 2. It has been shown that in all cases, under the given conditions, dehydrocyclization and isomerization of the alkanes occur, and both the alkanes themselves, and also benzene homologs formed as a result of catalytic dehydrocyclization, undergo methylation and hydrogenolysis. 3. It has been suggested that the methylene breakdown of alkanes and cycloalkanes plays a part in the formation of branched paraffins and higher benzene homologs. 4. A new concept has been advanced relating to the contact-catalysis isomerization reactions of alkanes at high temperatures in presence of hydrogen at high presure. © 1952 Consultants Bureau, Inc.
