This solution was further heated at reflux (150° C.) for one hour and then acetic acid was distilled off until the pot temperature reached 195° C. Heating of the mixture containing p-cresol acetate was discontinued and acetic anhydride (99 ml., 1.0 mole) was added. The mixture was cooled to 50° C. and anhydrous sodium acetate (131 g., 1.6 mole) was added followed by 3.0 g. of azobisisobutyronitrile (AIBN). After heating to 70° C. chlorine (49 g., 0.69 mole) was added through a gas dispersion tube below the surface of the liquid over a period of 1-2 hours while maintaining the temperature between 70°-75° C. The reaction was mildly exothermic and required some cooling. Upon completion of the chlorine addition, the p-acetoxybenzyl chloride thus obtained was converted to p-acetoxybenzyl acetate by refluxing (150° C.) the reaction mixture for 4 hours. The reaction mixture is cooled to 60°-65° C. and 10 ml. water is added to destroy remaining acetic anhydride. The temperature is controlled at 70°-75° C. while four 10 ml. portions of water are added at 30-minute intervals. The mixture is then cooled to 35° C. and drowned into 300 ml. water.
