Racemization of optically active tartaric acid

An optically active enantiomer of tartaric acid or a salt thereof is racemized by mixing meso-tartaric acid or a salt thereof with a solution of an optically active enantiomer of tartaric acid or a salt thereof in a molar ratio of 0.2 - 0.5 and thereafter heating the mixture.
