실험 절차

A mixture of 10 g of o-phenoxyanisol, 80 ml of hydroiodic acid (52%), 80 ml of acetic acid and 40 ml of acetic anhydride was refluxed for 1.5 hours. After being cooled, the reaction mixture was poured into ice-water to deposit a precipitate. The precipitate was dissolved in ether, and the solution was washed with an aqueous saturated sodium chloride solution, an aqueous saturated thiosulfuric acid aqueous solution and then an aqueous saturated sodium chloride solution. This ether solution was dried over anhydrous sodium sulfate, and the solvent was removed to give yellow solids. The solids were dissolved in acetic acid and stirred. The mixture was poured into cold water to deposit crystals. The crystals were washed with water and then with n-hexane, and dried at 80° C. under reduced pressure to obtain 7.8 g of o-phenoxyphenol as slightly yellow powders.
