摘要：

Recent results on the crystallisation/dissolution equilibrium of enantiomorphic crystals of NaClO3 lead to the conclusion that liquid-phase systems composed of achiral or fast racemising compounds yielding enantiomorphic solid phases (racemic conglomerates) can derive spontaneously to a single homochiral solid phase. This is a thermodynamically driven total resolution, which can only occur when the system is so perturbed that chiral recognition between the species of the system becomes feasible.
