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 catalyst:     
  • To synthesize nitriles from the corresponding aldehydes and hydroxylamine hydrochloride in the presence of sodium sulfate as a co-catalyst.      
  • To prepare coumarin derivatives via intramolecular Wittig reaction of substituted 2-formylphenyl 2-bromoacetates.      
  • In the acetylation of primary alcohols and phenols by reacting with acetic anhydride.
