ABSTRACT

The formation of diastereomeric cocrystals of malic acid and tartaric acid was investigated by liquid-assisted grinding in the solid state. We demonstrate that racemic malic acid can be converted into two distinct diastereomeric cocrystal phases by grinding with a single enantiomer of tartaric acid.
