Canceled
A process for producing graphene oxide (GO) product comprising forming a reaction mixture comprising a graphite-based precursor and an oxidizing effective amount of an oxygenation agent comprising a complex of hypofluorous acid (HOF) and an organic solvent-and mixing the reaction mixture for a time sufficient to cause oxidation of said graphite based precursor. Currently amended
The process of claim 28, wherein said organic solvent is an organic nitrile. Previously presented
The process of claim 28, wherein said graphite-based precursor is selected from the group consisting of graphite, expanded graphite, graphene, graphene nanosheets, carbon black, and graphite oxide. Previously presented
The process of claim 28, wherein said mixing is at a temperature of between 20 ° C to 30 °C. Previously presented
The process of claim 28, wherein said oxygenation agent comprises HOF-CH₃CN complex in water. Previously presented
The process of claim 28, comprising preparing Attorney Docket No. 067913-000710-the complex of HOF and the or g anic solvent prior to mixing with a graphite based precursor, said preparing comprises bubbling diluted fluorine (F₂) in nitrogen (N₂) through a solution of said organic solvent in water. Currently amended
The process of claim 28, wherein said-complex of HOF and the or g anic solvent is HOF-CH₃CN and said oxidizing effective amount thereof is between 0.2M to 1.OM. Currently amended
The process of claim 28, comprising quenching said-complex of the HOF and the or g anic solvent to obtain a quenched reaction mixture comprising graphene oxide, wherein said quenching is by diluting the reaction mixture with water or with an aqueous base. Currently amended
