Uses
(-)-Dibenzoyl-L-tartaric acid, anhydrous is used as a reagent used to produce chiral salts. Also used as organic chemical synthesis intermediate.
Flammability and Explosibility
Not classified
Safety Profile
Dibenzoyl-L-tartaric acid is an eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
Synthesis
A synthetic method of Dibenzoyl-L-tartaric acid includes the following steps: with L-tartaric acid and benzoyl chloride as raw materials, copper sulfate as a catalyst and toluene as a solvent, carrying out reaction to prepare L-dibenzoyl tartaric anhydride, carrying out hydrolysis with an equal amount of water and toluene to obtain the L-dibenzoyl tartaric acid, wherein the toluene serving as the solvent, as well as the water and the toluene in the hydrolysis step, can be repeatedly utilized.
