Description
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,[12] dissolution
testing[13] and
in impinger to remove acidic gases.[8] It
participates in the oxidation of glycerol catalyzed by Au/charcoal or
Au/graphite.[4] It
participates in solvent-free aldol condensation reaction.[7]
Application
Sodium hydroxide (NaOH) was used in the following processes:
• Preparation of sodium 3,3′-bis(sulfonato)-4,4′-
• Preparation of electrolyte solution to study the effect of electrolyte
composition on the conversion of CO2 to CO by electrochemical
reduction.[9]
• Preparation of CSK (cytoskeleton) buffer for the three-dimensional (3D)
slide method of preserving the 3D chromatin structure of testicular germ cells.[10]
• Synthesis of ZSMs (zeolite socony mobils).[11]
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-teroctylphenoxyethoxyethoxye
• trisulfobetaines (TriSBn)[3]
Sodium hydroxide may be used as a base in titration methods[12],
dissolution testing[13],
for adjusting pH[14] and
in the impinger to remove acidic gases.[12]
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.
