Descrizione

Descrizione generale

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.

Applicazioni

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. For general uses, product is also available in powdered form (223530)

Caratteristiche e vantaggi

ChemBeads are chemical coated glass beads. ChemBeads offer improved flowability and chemical uniformity perfect for automated solid dispensing and high-throughput experimentation. The method of creating ChemBeads uses no other chemicals or surfactants allowing the user to accurately dispense sub-milligram amounts of chemical.
