| titleOfInvention | A kind of preparation method of oxidation C60 |
| abstract | The invention discloses a preparation method of oxidized C60 . Including (1) adding 65% concentrated nitric acid to the reactor first, then adding 98% concentrated sulfuric acid, stirring in an ice-water bath to obtain a mixed acid, and controlling the temperature at 5‑10°C; (2) adding C60 into it, stirring, The temperature is controlled at 5-10°C; (3) Gradually and slowly add potassium permanganate in batches, the interval between each addition is 15min, and the ice-water bath keeps the temperature at about 10°C for reaction; (4) Drain the ice water and heat to Reaction at 50°C for a total of 10-20 hours; (5) Cool the reaction mixture to room temperature, slowly add water dropwise to dilute, and the solution temperature is below 40°C; (6) Add hydrogen peroxide into the solution, let it stand, and pour off the supernatant; ( 7) The sample was washed with an appropriate amount of 5% HCl and pure water to remove metal ions, and the prepared C60 oxide was dried at 100° C. and stored. Using mixed acid and potassium permanganate to oxidize C 60 , so that the oxidized C 60 contains a large number of oxygen-containing functional groups such as carboxyl and hydroxyl. |
