长链正构烷烃在短链烷烃中的溶解度数据已被用于预测在较低温度下稳定的多晶相的熔融温度。在烷烃的情况下，没有多晶型相（十六烷和十八烷）的预测的熔融温度与传统的纯烷烃的熔融温度是一致的。具有多晶型相的烷烃的熔融温度的预测是一致的纯烷烃（二十四烷，二十六烷，二十八烷，三十二烷和hexatriacontane）的转变温度。纯偶数正构烷烃的多晶型相之间的转变通过在较低温度下稳定的固相的熔融温度下的过渡液态进行。
Solubility data for long-chain n-alkanes in shorter-chain alkanes have been used to predict the melting temperatures of the polymorphic phase stable at lower temperatures. In the case of alkanes having no polymorphic phases (hexadecane and octadecane) the predicted melting temperatures are consistent with the conventional melting temperature of the pure alkanes. The predicted melting temperatures of alkanes possessing polymorphic phases are consistent with the transition temperatures of pure alkanes (tetracosane, hexacosane, octacosane, dotriacontane and hexatriacontane). The transition between the polymorphic phases of pure even n-alkanes proceeds by the transitional liquid state at the melting temperatures of the solid phases stable at lower temperatures.
