本文综述了有机化合物的固相反应化学。三个测试进行了讨论，这表明，在这样的反应中的控制因素之一是反应物物种的晶体结构的几何形状：（1）化学上密切相关的化合物显示出显着的差异，在固态的化学行为;（2）一个给定的化合物反应不同的固相和分散相;（3）多晶型修饰的一个给定的化合物显示出显着的差异，在化学行为。这些证据被解释为“拓扑化学”假设，即固态反应发生时原子或分子运动最少。
A survey is presented of the chemistry of solid-state reactions of organic compounds. Three tests are discussed which indicate that one of the controlling factors in such reactions is the geometry of the crystal structure of the reactant species:(1) chemically closely-related compounds show significant differences in chemical behaviour in the solid state;(2) a given compound reacts differently in the solid and dispersed phases;(3) polymorphic modifications of a given compound show significant differences in chemical behaviour. The evidence is interpreted in terms of the “topochemical” postulate that reaction in the solid state occurs with a minimum of atomic or molecular movement.
