Application: | Sodium hydroxide may be employed for the direct oxidation of sodium borohydride, which was investigated by cyclic and linear voltammetry, chronoamperometry and chronopotentiometry. It may be used to compose citrate buffer and borate buffers. It may be used in the synthesis of following compounds: • alkylaryl amidosulfobetaines • (3-[ 4-teroctylphenoxyethoxyethoxye • trisulfobetaines (TriSBn) |
General description: | Sodium hydroxide (NaOH) is an inorganic base. It participates in the oxidation of glycerol catalyzed by Au/charcoal or Au/graphite. It also participates in solvent-free aldol condensation reaction. |
Other Notes: | Reagent for the decomposition of silicates by fusion |
