General description
Sodium hydroxide (NaOH) also known as caustic soda is a water soluble inorganic base with a wide range of industrial application such as titration, dissolution testing and in impinger to remove acidic gases. It participates in the oxidation of glycerol catalyzed by Au/charcoal or Au/graphite. It participates in solvent-free aldol condensation reaction.
Application
Sodium hydroxide (NaOH) was used in the following processes:
- Preparation of sodium 3,3′-bis(sulfonato)-4,4′-bis(chloroacetamido)azobenzene (BSBCA) that is utilized in protein cross-linking techniques.
- Preparation of electrolyte solution to study the effect of electrolyte composition on the conversion of CO2 to CO by electrochemical reduction.
- Preparation of CSK (cytoskeleton) buffer for the three-dimensional (3D) slide method of preserving the 3D chromatin structure of testicular germ cells.
- Synthesis of ZSMs (zeolite socony mobils).
- alkylaryl amidosulfobetaines
- (3 -[4-teroctylphenoxyethoxyethoxyethyl] dimethylammonio propane sulfonate (XOSB)
- trisulfobetaines (TriSBn)
Sodium hydroxide may be used as a base in titration methods, dissolution testing, for adjusting pH and in the impinger to remove acidic gases.
It may be used in the following processes:
- Conversion of glycerol to glyceric acid in the presence of gold catalyst.
- Palladium-catalyzed cross-coupling reaction between vinylalkoxysilanes and aryl bromides or chlorides to form styrenes.
