Description
- General description: Sodium carbonate (Soda) is a white salt. It can be synthesized by the electrolysis of the molten sodium hydroxide or sodium chloride.[1]
- Application: Sodium carbonate may be used as a reducing agent for the preparation of graphene sheets with good electrocapacity from graphene oxide dispersion.[5]It may also be used in procedures for the synthesis of the following:Biaryls via palladium-catalyzed cross-coupling reaction of phenylboronicacid with haloarenes.[6]Chalcones and azachalcones via aldol condensation of aldehydes with ketones in aqueous medium.[7]Enynes via copper-catalyzed allylation of functionalized alkynes.[2]
- Biochem/physiol Actions: Buffer component, may be used for the removal of peripheral membrane proteins.
