4,4'-Dihydroxybiphenyl → 4,4'-Bis(octyloxy)-1,1'-biphenyl

Participants

Reaction Steps

56 g of 4,4′-dihydroxybiphenyl was dissolved in 500 g ethanol. To this solution was added 40 g of potassium hydroxide, and the mixture was reacted. Next, this solution was heated, and 128 g of 1-bromooctane was dropped at 70° C., and subsequently, the mixture was reacted at 70° C. for 7 hours. The reaction was performed under a nitrogen atmosphere. After the reaction, this solution was cooled, and the generated precipitate was filtrated to recover. Next, this precipitate was washed with 500 ml of methanol, then, washed with a mixed solvent of methanol 500 ml/ion exchanged water 300 ml, and further, washed with a mixed solvent of acetone 500 ml/ion exchanged water 300 ml. This precipitate was dried under reduced pressure, to obtain 105 g of 4,4′-dioctyloxybiphenyl represented by the following structural formula:
