In 4000 ml of acetone was dissolved 500 g (4.2 moles) of p-hydroxybenzonitrile and 965 g (5.0 moles) of octyl bromide, 828 g (6.0 moles) of anhydrous potassium carbonate was added thereto, and the mixture was refluxed with heating for 30 hours. Then, the inorganic salt was filtered off from the reaction mixture, acetone was distilled under reduced pressure. To the residue was added 2000 ml of ether and the mixture was washed with 2N aqueous solution of sodium hydroxide, water, then saturated aqueous solution of sodium chloride. The resulting organic layer was dried with anhydrous magnesium sulfate, and ether was distilled under reduced pressure to give 855 g of p-octyloxybenzonitrile (yield: 88%).
