The partial sublimation of enantioenriched amino acids was performed slowly at low temperature with the aim to determine the rules of sublimation of these compounds. Although the formation of a euatmotic composition of the gaseous phase starting from DL + L mixtures of Leu, Pro, and Phe can be deduced from the enantiomeric excess of sublimates, the behavior of the kinetic conglomerate explains the results for D + L mixtures of Ala, Leu, Val, and Pro. Consequently, the enantiomeric excess of the partial sublimate is dependent not only on the studied compound but also on the composition of the starting mixture.
对(enantioenriched)氨基酸进行部分升华处理，在低温下缓慢进行，目的是确定这些化合物升华的规律。尽管可以从 DL+L 混合物的 Leu、Pro 和 Phe 的升华物的对映过量推断出气相间形成等摩尔组成，但动力学聚集体的行为解释了 Ala、Leu、Val 和 Pro 的 D+L 混合物的结果。因此，部分升华物的对映过量不仅取决于研究的化合物，还取决于起始混合物的组成。
