ABSTRACT:
Alkali metal bicarbonate salts, e.g., sodium bicarbonate, are crystallized from aqueous solutions thereof in the presence of a crystal growth promoting amount of lecithin or lecithin containing compositions. Alkali metal bicarbonate salts include sodium bicarbonate, potassium bicarbonate and lithium bicarbonate. The process is described as providing increased amounts of large crystals and a narrower and more uniform crystal size distribution.
