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.

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 weak base. Its aqueous solution has the ability to uptake carbon dioxide. It can also catalyze the conversion of sewage sludge to liquid fuels.
