The optical isomers of racemic 1,2-diols are separated by an essentially enzymatic process involving the following operations
reaction of the racemic mixture of the 1,2-diols with an organic anhydride in the presence of an enzyme belonging to the class of lipases;
separation of the enzyme;
removal of the excess anhydride;
separation of the esters produced in optically pure form by column chromatography;
recovery of the 1,2-diols as optically pure enantiomers.
