FIELD: chemistry.
SUBSTANCE: method includes the following stages: a. hydration of lactides, where metal-catalysed heterogeneous catalysis is performed in presence of hydrogen with obtaining non-purified product, containing propane-1,2-diol, and b. dynamic kinetic separation of racemates, in which optically pure propane 1,2-diol is obtained in range ≥ 99% e.e.
EFFECT: improvement of compound properties.
