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.
近期关于氯酸钠对映体晶体结晶/溶解平衡的研究结果表明,由非手性或快速外消旋化合物组成的液相体系,若能产生对映体固相(外消旋聚集体),则可自发地转变为单一的纯手性固相。这是一种由热力学驱动的完全拆分,只有当体系受到足够扰动,使得体系中各物种之间的手性识别变得可行时才会发生。
