Procedure

In a 1-liter autoclave equipped with a stirrer were placed 35.8 g of a 10% palladium black catalyst and all of the above-mentioned crude o-isobutylstyrene, and hydrogenation was carried out at a reaction temperature of 50° C. under a hydrogen pressure of 20 kg/cm2. After hydrogen had not been absorbed any more, the used catalyst was removed from the reaction mixture by filtration, followed by distillation, thereby obtaining 642 g of o-isobutylethylbenzene having 99.8% purity.
