摘要
Abstract Crystallization of sodium acetate trihydrate from water affords hexagonal plates. When crystallized from cyclohexane, a solvent in which this salt is completely insoluble but in which it may be solubilized by macrocyclic crown polyethers, needle-shaped crystals are produced. This habit change is consistent with selective solvation of hydrophilic vs. hydrophobic crystal faces by water and cyclohexane, respectively. Potassium hydrogen tartrate crystallizes from warm water in the form of prisms elongated along [001]. Crystallization at water/organic solvent (chlorinated hydrocarbon) interfaces, again mediated by the formation of organic solvent-soluble complexes with macrocyclic crown polyethers, affords distinctive prism forms. In these two-phase (aqueous/organic) solvent systems, the nature of the solvent and/or the crown polyether plays a significant role in determining crystal form.

摘要醋酸钠三水合物从水中结晶提供六边形板。当从环己烷中结晶时，该盐完全不溶的溶剂，但其中可以通过大环冠聚醚溶解，产生针状晶体。这种习惯变化与水和环己烷的亲水性与疏水性晶面的选择性溶剂相一致。酒石酸钾通过沿着沿着沿[001]的棱镜形式从温水中结晶。在水/有机溶剂（氯化烃）界面中结晶，再次通过与大环冠聚醚的形成有机溶剂可溶性络合物进行介导的，得到了独特的棱镜形式。在这些两相（水/有机/有机）溶剂体系中，溶剂和/或冠聚醚的性质在确定晶体形式中起着重要作用。
