    Abstract: A process is disclosed for the hydrogenation of 1-phenyl-1,3,3trimethylindane to prepare selected isomers. For example 4,9-cis, 1-cyclohexyl-1,3,3-trimethylhydrindane, a fluid with improved tractive properties, can be prepared using a catalyst containing nickel, palladium or rhodium at a hydrogen pressure in the range of 600 to 1500 p.s.i.g., and a temperature substantially in the range of 200*C. to 225*C.
