| 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. |
| 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. |
