Embodiments relate to the field of hexagonal boron nitride (hBN). In particular, to an alkali metal (A) intercalated hBN material. The A-intercalated hBN is chemically active, electrically conducting, and superconducting. The A-intercalated hBN is spontaneously soluble in aprotic organic solvents to form dispersions of exfoliated reduced 2-dimensional hBN sheets in organic solvents. The dispersions of exfoliated reduced 2-dimensional hBN materials in organic solvents materials can be reacted with metal salts to form 2-dimensional hBN-supported metal and/or metal oxide nanoparticle composites. The solutions/dispersions of exfoliated reduced 2-dimensional hBN materials in organic solvents can be transferred to water or organic solvents to form stable aqueous and organic suspensions of 2-dimensional hBN.

A sodium ion battery comprises a cathode having a porous redox active metal-organic framework material. The battery can be an organic electrolyte sodium ion battery wherein the electrolyte comprises a sodium salt dissolved in an organic solvent or mixture of organic solvents. Alternatively, the battery can comprise an aqueous sodium ion battery wherein the electrolyte comprises a sodium salt dissolved in an aqueous solvent. Battery performance is especially related to electrolyte and binder selection.

A process of purifying acetic acid is provided. The process includes feeding a stream of acetic acid into a distillation column and distilling acetic acid in the presence of an oxidizing agent in the distillation column, to oxidize oxidizable impurities in the acetic acid, wherein the oxidizing agent is an oxidant capable of cleaving CC bonds. The process further includes removing a distilled acetic acid stream from the distillation column. Further processes for purifying acetic acid and systems for purifying acetic acid are also provided.

A process for producing a hexafluorophosphate salt comprises neutralizing hexafluorophosphoric acid with an organic Lewis base, to obtain an organic hexafluorophosphate salt. The organic hexafluorophosphate salt is reacted with an alkali hydroxide selected from an alkali metal hydroxide (other than LiOH) and an alkaline earth metal hydroxide, in a non-aqueous suspension medium, to obtain an alkali hexafluorophosphate salt as a precipitate. A liquid phase comprising the non-aqueous suspension medium, any unreacted organic Lewis base and any water that has formed during the reaction to form the precipitate, is removed. Thereby, the alkali hexafluorophosphate salt is recovered.
