| Abstract: | A new efficient and simple procedure was developed for the preparation of expandable sulfurfree graphite by using potassium permanganate as the oxidant,a mixture of 95% nitric acid and 995% propanoic acid as insertion reagentsThe experimental conditions were optimized as the following: the mixing ratio of graphite,995% propanoic acid,95% nitric acid and potassium permanganate is 10506006(by mass); the reaction time is 40 min at 25 The compositions of the expandable graphite were analyzed by mass spectrometry and elemental analysis |
