溶剂极性对马来酸氢十六烷酯(HHM)晶体生长的影响

The effects of solvent′s polarity on crystal growth of hexadecyl hydrogen maleate (HHM)

选用几种极性不同的有机溶剂,采用恒温蒸发法进行了马来酸氢十六烷酯(HHM)晶体在溶剂中的结晶性实验和晶体生长实验,结果发现溶剂极性对HHM晶体生长影响很大,采用极性低的溶剂HHM能呈现很好的结晶性并能生长出质量优良的晶体,极性大的溶剂则表现出相反的结果,并讨论了HHM在溶液中分子缔合情况和HHM晶体生长面对溶剂的吸附现象。

In this article crystallinity and crystal growth of hexadecyl hydrogen maleate (HHM) was studied by thermostatic evaporating with different polar solvent. The result was that polar of the solvent has great effect on crystal growth. When the solvent with low polar was used, HHM crystal involved in very good crystallinity and came into eximious quality crystal. It was reversed with high polar solvent. And the molecular association and the menstruum adsorption phenomenon of crystal growing section in solvent were also studied.
