Abstract

In contrast to what is often expressed in the literature, reversible and irreversible solid(s)-solid(s) transitions in binary system of non-racemizable enantiomers are not always referred to as polymorphism. Order-disorder phenomena, miscibility gaps with critical temperatures and transitions in which three-phases or even four-phases are involved can also occur. In the case of reversibility, three-phase invariants such as eutectoid or peritectoid corresponding to the reversible formation or decomposition of racemic compounds are described. The heterogeneous equilibria are reviewed with or without miscibility in the solid state. Several four-phase invariants and order-disorder transitions are predicted.

对映体二元体系中缩合相非均相平衡的研究进展。
与文献中经常表达的相反,不可消旋对映体二元体系中可逆和不可逆的固体-固体转变并不总是被称为多态性。有序-无序现象,临界温度下的混相间隙和三相甚至四相的转变也可能发生。在可逆性的情况下,描述了与外消旋化合物的可逆形成或分解相对应的三相不变量,如共析或包析。回顾了固体中有无混相的非均相平衡。预测了几种四相不变量和有序-无序转变。
