3-(2-chloro-5-methylphenoxy)propane-1,2-diol 3 were prepared in racemic and single-enantiomer forms. For all the studied compounds phase behavior during crystallization was established on the basis of IR, DSC and X-ray investigations. Absoluteconfigurations were established for compounds 1 and 2 . Being conglomerate, racemic oxirane 2 was resolved by direct entrainment procedure. Being anticonglomerate
