Hydrochloric Acid → Phosphonic acid, P-decyl-

Participants

Reaction Steps

To a solution of n-decylphosphonous acid (1 g, 0.0048 mole) in acetone (10 ml) and water (10 ml) was added a solution of sodium hydroxide (0.19 gm, 0.0047 mole) in water (5 ml) until a pH of about 7 was reached. A solution of KMnO4 (0.46 gm, 0.0029 mole) in water (5 ml) was added solwly to the vigorously stirred solution of phosphonous acid at 20-25° C. After the addition (5 minutes), the reaction mixture was stirred for 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.
