General description

Sodium bicarbonate (NaHCO3), generally known as baking powder, is commonly used as a base in many organic reactions. Recently, it has also been used in organic electronic devices as an electron injection layer material.

Application

Sodium bicarbonate can be used:
  • As a catalyst or a promoter in the acetylation of phenols and primary alcohols using acetic anhydride.
  • In the synthesis of sugar orthoesters.
  • In the asymmetric isomerization studies of cyclic dienes.
