一般描述

Sodium hydroxide participates in the oxidation of glycerol catalyzed by Au/charcoal or Au/graphite. It also participates in solvent-free aldol condensation reaction.

应用

Sodium hydroxide may be employed for the determination of specific surface area of colloidal silica, via titration. It 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 :
  • 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.
