马来酸氢长碳链酯分光晶体的合成及结晶习性的研究

合成了马来酸氢长碳链酯系列分光晶体的材料，并分别选用几种不同极性的有机溶剂进行了晶体结晶性能实验。结果发现溶剂的极性对晶体生长的外形影响很大。非极性或低极性的溶剂适合于长碳链酯完整晶形的生长。在苯溶剂中晶体能呈现很好的结晶性能，生长出数目少，外形完整，表面光洁无添晶质量优良的晶体。在同种极性的溶剂中，随着酯的碳链缩短，表现为更好的结晶性。本文还讨论了晶体和溶液中溶质结构基元的缔合形式和晶体生长面溶剂的吸附情况。

The effect of solvent's polarity on crystal growth conformation of ester of maleate acid

In this article, the analyzer crystal materials of series of esters of maleate acid had been synthesized. And finish the crystal capability experiments of these crystals in the different polar solvents. The result was that the polarity of solvent makes great effort to the appearance of the crystal. In the solvent with low polarity or non-polarity complete crystal of series of esters adapted to grow. For example, in the benzene solvent the crystal could show good crystal capability and grow excellent crystal. This kind of good crystal the amount was a few, the shape of it was clear and its surface was clean. And it show better crystal capability in the same polarity solvent when the carbon chain was longer. In this article we also research the molecular association and the menstruum adsorption phenomenon of the crystal growing section in the solvent.
