Diphenylamine reacts with benzophenone in the solid state through the formation of a eutectic liquid intermediate, from which the final product, in the form of a hydrogen-bonded cocrystal, is finally formed. By a simple experiment, the phase diagram of the benzophenone/diphenylamine system is effectively divided into two parts, which enabled monitoring of the overall process from the side of each reactant separately. Accompanied by isothermal and nonisothermal spectroscopic monitoring of the system, this provides additional details of the mechanistic pathway of the process of cocrystal formation through a metastable liquid intermediate phase.

二苯胺-苯甲酮系统中准固态扩散驱动共结晶的原位监测
二苯胺通过形成共晶液体中间体与固态的二苯甲酮反应，从中最终形成氢键合共晶形式的最终产物。通过一个简单的实验，将二苯甲酮/二苯胺系统的相图有效地分为两部分，从而可以从每种反应物的侧面分别监视整个过程。伴随着系统的等温和非等温光谱监测，这提供了通过亚稳液相中间相形成共晶过程的机械途径的更多细节。
