    Celecoxib–Nicotinamide Cocrystal Revisited: Can Entropy Control Cocrystal Formation?
    摘要:
    对塞来昔布-烟酰胺共晶体进行了重新研究,以揭示其晶体结构和不寻常的形成特性。通过溶解度和热分析测定了 25 °C 时的吉布斯自由能和形成焓。研究发现,塞来昔布-尼可丁酰胺的形成是一个由熵驱动的内热过程,这一机制与许多已报道的共晶体不同,但与之前报道的晶格能计算结果一致。根据热力学数据预测并经实验证实,这种共晶体只有在过渡温度以上才会稳定。这种形成机制为从结构预测到工艺开发的共晶研究提供了新的机遇,并丰富了我们对共晶性质的理解。
