100 g of cardanol in solvents (100 cm3) such as ethyl acetate, methanol and the like was hydrogenated in a parr hydrogenator at 30-60 psi pressure by using catalysts (50 mg) such as palladised carbon, platinum oxide, raney nickel and the like. at 30-100° C. The hydrogenation was carried out for 2-4 hrs. The solution was filtered to remove the catalyst and methanol stripped off. The crude 3-pentadecyl phenol was distilled under vacuum (4 mm of Hg). The fraction which distilled at 200° C. to 210° C. was collected. The white solid obtained was recrystallised from hexane twice to obtain pure 3-pentadecyl phenol.
