General description
Sodium carbonate (Soda) is a white salt. It can be synthesized by the electrolysis of the molten sodium hydroxide or sodium chloride.
Sodium carbonate is a water soluble inorganic salt commonly used as a weak base. Its aqueous solution has the ability to uptake carbon dioxide. It can also catalyze the conversion of sewage sludge to liquid fuels.
Application
Sodium carbonate may be used as a reducing agent for the preparation of graphene sheets with good electrocapacity from graphene oxide dispersion.
It may also be used in procedures for the synthesis of the following:
Biaryls via palladium-catalyzed cross-coupling reaction of phenylboronicacid with haloarenes.
Chalcones and azachalcones via aldol condensation of aldehydes with ketones in aqueous medium.
Enynes via copper-catalyzed allylation of functionalized alkynes.
Sodium carbonate may be used in the following studies:
Determination of total polyphenolic index of wine products from grape by the Folin-Ciocalteu method.
To compose the ELISA (Enzyme-Linked Immunosorbent Assay) coating buffer.
Preparation of the antibody coating buffer for use in IGF-I kinase receptor activation assay (KIRA) assay.
