摘要:

有些消旋体结晶过程中的自发拆分会导致对映异构体单晶呈现不同的外观状态。本文总结并列举了根据外观辨识单一手性晶体的四种方式,包括:半面体面、宏观形态、偏光颜色和表面形貌。这些“以貌取人”的方法为探究手性化合物的结晶行为提供了重要的工具和见解。

关键词: 自发拆分, 半面体面, 宏观形态, 偏光颜色, 表面形貌

Abstract:

During the crystallization process of certain racemic compounds, spontaneous resolution can lead to distinctive external appearances of enantiomeric crystal forms. This article offers a comprehensive overview and delineates four methods for identification, namely, examining hemihedral faces, assessing macromorphology, employing circular polarization, and analyzing surface topography. These identification techniques serve as invaluable tools and viewpoints for studying the crystallization behavior of chiral compounds, holding significant potential across diverse applications in pharmaceutical production, materials science, and chemical synthesis.

Key words: Spontaneous resolution, Hemihedral faces, Macromorphology, Circular polarization, Surface topography
