설명

일반 설명

Sodium hydroxide (NaOH) 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]

애플리케이션

Sodium hydroxide may be employed for the direct oxidation of sodium borohydride, which was investigated by cyclic and linear voltammetry, chronoamperometry and chronopotentiometry.[3] It may be used to compose citrate buffer and borate buffers.[4]
It may be used in the synthesis of following compounds:[5]

• alkylaryl amidosulfobetaines
• (3-[ 4-teroctylphenoxyethoxyethoxyethyl] dimethylammonio propane sulfonate (XOSB)
• trisulfobetaines (TriSBn)

기타 정보

Reagent for the decomposition of silicates by fusion[6][7]
