Reactant 2

HCID 1118Sulfuric Acid

HCID 13725893Calcium d-tartrate

Product 1

HCID 439655D-Tartaric acid

Procedure

Sulfuric acid is added in calcium D-(-)-tartarate to precipitate calcium sulfate and D-(-)-tartaric acid is separated in water. D-(-)-tartaric acid can be obtained by concentrating the aqueous solution. Refined D-(-)-tartaric acid can be obtained by recrystallizing from water.
