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.[2]
• Preparation of electrolyte solution to study the effect of electrolyte composition on the conversion of CO2 to CO by electrochemical reduction.[10]
• Preparation of CSK (cytoskeleton) buffer for the three-dimensional (3D) slide method of preserving the 3D chromatin structure of testicular germ cells.[11]
• Synthesis of ZSMs (zeolite socony mobils).[12]
Sodium hydroxide may be employed for the deterimination of specific surface area of colloidal silica, via titration.[5] It may be employed for the direct oxidation of sodium borohydride, which was investigated by cyclic and linear voltammetry, chronoamperometry and chronopotentiometry.[6] It may be used to prepare citrate buffer and borate buffer.[1] It may be used in the synthesis of :
• alkylaryl amidosulfobetaines[3]
• (3 -[4-teroctylphenoxyethoxyethoxyethyl] dimethylammonio propane sulfonate (XOSB)[3]
• trisulfobetaines (TriSBn)[3]
Sodium hydroxide may be used as a base in titration methods[8], dissolution testing[13], for adjusting pH[14] and in the impinger to remove acidic gases.[8]
It may be used in the following processes:
• Conversion of glycerol to glyceric acid in the presence of gold catalyst.[15]
• Palladium-catalyzed cross-coupling reaction between vinylalkoxysilanes and aryl bromides or chlorides to form styrenes.
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,[8]dissolution testing[13] and in impinger to remove acidic gases.[9] It participates in the oxidation of glycerol catalyzed by Au/charcoal or Au/graphite.[4] It participates in solvent-free aldol condensation reaction.[7]
