Popis

General description

Sodium bicarbonate is commonly known as baking soda. It serves as a source of carbon dioxide and is used to prepare a variety of sodium salts. It is also an important pH-regulating agent.

Application

Sodium bicarbonate can be used as a reactant to synthesize monosodium Schiff bases by the condensation reaction of aldehydes and amino acids.

Features and Benefits

• Increased efficiency – Eliminates time and effort of loosening hardened powders      
• Safety – Eliminates tools of force used to break up clumps
• Ecology – Reduces waste as it does not stick to the packaging
• Economy – Faster preparation and solvation increase productivity and reduce costs     
• Assured Quality – Excellent, expert-tested quality with no anti-caking agents
• Flexible volumes – Available from research amounts to scale-up quantities
