    General description

    Sodium carbonate (soda ash) is an inorganic chemical compound. It is used in the synthesis of chemicals, detergent formulations, flue gas desulfurization, and paper and pulp production.

    Application

    Sodium carbonate can be used:
    • As a catalyst in the aldol condensation of aldehydes with ketones in the synthesis of chalcone and azachalcone.
    • As a pH stabilizer agent in the synthesis of FeO-NPs (iron oxide nanoparticles) in the presence of cymbopogon citratus as a reducing agent.
    • As a base in the Pd-catalyzed Suzuki coupling reactions.
    • As a base in the transition metal free Suzuki coupling reaction of aryl halides and arylboronic acids to form biaryls using water as a solvent and TBAB (tetrabutylammonium bromide) as a phase-transfer catalyst.

    Biochem/physiol Actions

    Buffer component, may be used for the removal of peripheral membrane proteins.
