Preparation
The tartrates used in commerce are obtained as a by-product of wine manufacture and have the L(+) configuration.
Produced from argols or wine lees, which are formed in the manufacture of wine by extracting the potassium acid tartrate, transforming this into the calcium salt and then acidifying with dilute sulfuric acid; also by oxidation of d-glucose with nitric acid.
The dl-tartaric acid is obtained by boiling the d-tartaric acid with an aqueous solution of NaOH or by oxidation of fumaric acid.
The l- and the meso-tartaric acid are also known, but are less important.
