Abstract:
1. A nitrate salt-based process for manufacturing graphite oxide, the process comprising steps of: (a) mixing in a reaction vessel a reaction mixture comprising the following starting materials: a sulfuric acid, an inorganic nitrate salt, and an amount of water; (b) allowing the reaction mixture to react; (c) adding to the reaction mixture prepared according to (b) a graphite and allowing the reaction mixture to react; (d) adding a chlorate salt to the reaction mixture prepared according to (c) while monitoring the temperature of the reaction mixture such that the chlorate salt is added at a rate that maintains the temperature of the reaction mixture below 5° C., and thereby forming graphite oxide; and (e) separating the graphite oxide from the reaction mixture to give an isolated graphite oxide.
