  铅（ii）肥皂：晶体结构，多态性以及固体和液体中间相†

  摘要：

  链烷酸铅（II）系列或肥皂的长链成员，从辛酸酯到十八烷酸酯，已通过XRD，PDF分析，DSC，FTIR，ssNMR和其他技术在所有阶段和中间阶段进行了全面表征。现在解决了该系列所有成员在室温下的晶体结构，表明在室温晶体相中存在两种多晶型，不同于短链和长链成员。只有壬酸和癸酸两种形式都存在，并且该多态性被证明是单向的。在更高的温度下，这些化合物呈现出固态中间相（定义为旋转体），液晶相和液相，所有这些均具有相似的局部排列。由于一些铅（二）肥皂在油画中作为降解化合物出现，解决的铅（II）肥皂晶体结构现在可以用作指纹图谱，以进行X射线衍射检测。这些化合物的对分布函数分析在不同成员的相同相和中间相中非常相似，显示了相同的短程顺序。该观察结果表明，该技术还可以用于检测无序相或绘画形成初期的这些化合物。
