Versuchsvorschrift

To a solution of phenylphosphonous acid (1 g, 0.007 mole) in acetone (10 ml) and water (10 ml) was added a solution of sodium hydroxide (0.281 gm, 0.007 mole) in water (10 ml) until a pH of about 7 was reached. A solution of KMnO4 (0.663 g, 0.007 mole) in water (10 ml) was added slowly to the vigorously stirred solution of phosphonous acid at 20°-25° C. After the addition (5 minutes), the reaction mixture was stirred for 5 minutes at ambient temperature and acidified with concentrated HCl acid until a pH of 1 was reached. Saturated sodium bisulfite solution was added to the reaction mixture thereby resulting in formation of a precipitate.
