10 g of 4-nonylphenol (manufactured by Tokyo Kasei K.K., containing 10% of ortho compound) was dissolved in 30 ml of acetic acid and to the resulting solution was added 20 ml of 30% solution of nitric acid at 5°-10° C. for 2 hours. After 10 minutes, the resulting solution was treated with 50 g of ice water and then extracted with three 50-ml portions of ether. The ether was distilled off and then the residue was isolated using a silica gel column to obtain 9.33 g of the desired product in a 78% yield.
