Vorschrift

Raney Ni catalyst (0.5 g) was added to a solution of 1,4-bis[4-(trans-4-propylcyclohexyl)cyclohexen-1-yl]benzene (0.9 g) dissolved in toluene (70 ml), followed by subjecting to catalytic reduction at ordinary temperature under ordinary pressure, tracing the reaction by gas chromatography and stopping the reaction when the raw material disappeared. Since the product was a mixture of cis-form and trans-form substances, it was recrystallized from toluene to obtain an objective product, 1,4-bis[trans-4-(trans-4-propylcyclohexyl)cyclohexyl]benzene (yield: 0.3 g, C-Sm point: room temperature or lower, Sm-I point: 300° C. or higher).
