Claim 1
Independent Claim
71 words
A PROCESS FOR PRODUCING A CYCLOALKYLPERHYDROINDAN HYDROCARBON WHICH COMPRISES EFFECTING A HYDROGEN TRANSFER REACTION IN THE PRESENCE OF AN ACID-ACTING CATALYST BETWEEN A BRANCHED CHAIN OLEFIN AND A PARA-DI-SUBSTITUTED AROMATIC HYDROCARBON HAVING AS ONE SUBSTITUENT A HYDROCARBON GROUP CONTAINING ONLY ONE HYDROGEN ATOM JOINED TO THE CARBON ATOM COMBINED WITH THE AROMATIC RING TO FORM AN ARYLINDAN HYDROCARBON, HYDROGENATING SAID ARYLINDAN HYDROCARBON TO A CYCLOALKYLPERHYDROINDAN HYDROCARBON AND RECOVERING SAID CYCLOALKYLPERHYDROINDAN HYDROCARBON.
Claim 2
Dependent Claim
