The tendency to crystallize was studied in the selected monohydroxy alcohols: 1-chloro-2-methyl-2-propanol, 1-chloro-2-propanol, 3-chloro-1-propanol, and 8-chloro-1-octanol. Performed calorimetric measurements have proved that the differences in structures of tested alcohols influence the tendency to crystallization. At a sufficiently fast heating rate, no crystallization was observed in the case of 1-chloro-2-propanol and 3-chloro-1-propanol, contrary to other two alcohols. The obtained results suggest that elongation of the alkyl chain or adding a methyl group to the hydrocarbon backbone increases the susceptibility to crystallization.

一元醇分子结构的差异如何影响结晶倾向

在选定的单羟基醇中研究了结晶的趋势：1-氯-2-甲基-2-丙醇、1-氯-2-丙醇、3-氯-1-丙醇和8-氯-1-辛醇。进行的量热测量已经证明，被测醇的结构差异会影响结晶的趋势。在足够快的加热速率下，在 1-氯-2-丙醇和 3-氯-1-丙醇的情况下没有观察到结晶，这与其他两种醇相反。获得的结果表明，烷基链的延长或向烃主链添加甲基会增加结晶的敏感性。
