General description

Sodium hydroxide is an inorganic base. It participates in the oxidation of glycerol, catalyzed by Au/charcoal or Au/graphite.[1] It also participates in solvent-free aldol condensation reaction.[2]

Application

Sodium hydroxide may be employed for determination of specific surface area of colloidal silica, via titration.[3] It may be employed for direct oxidation of sodium borohydride, which was investigated by cyclic and linear voltammetry, chronoamperometry and chronopotentiometry.[4] It may be used to compose citrate buffer and borate buffers.[5]
It may be used in the synthesis of following compounds:[6]
  • alkylaryl amidosulfobetaines
  • (3 -[4-teroctylphenoxyethoxyethoxyethyl] dimethylammonio propane sulfonate (XOSB)
  • trisulfobetaines (TriSBn)

Severe quantitative loss of protein is often observed in high-resolution two-dimensional electrophoresis of membrane proteins, while the resolution is usually not affected. To improve the solubility of proteins in this technique, we tested denaturing cocktails containing various detergents and chaotropes.
