摘　　要：采用不同比例的丙酮-乙醇混合溶剂取代单一溶剂,测定了1-氰基金刚烷在其中的溶解度曲线和过饱和度曲线,确定了晶体生长的亚稳区范围.研究发现,随着丙酮浓度增大溶解度明显增大,当丙酮浓度为70%,饱和温度为35℃时,亚稳区宽度最宽,稳定性更好,更适合1-氰基金刚烷单晶生长.A single solvent was instead by the mixed solvent with a different ratio of ethanol-acetone in this pa- per. The solubility curve and super saturation curve of 1-cyanoadamantane were measured, which determined the metastable region range of crystal growth. The study found that the solubility increased obviously with the increase of acetone concentration, when the acetone concentration was 70% and the saturation temperature was 35 ℃, the metastable region had the widest width and better stability, which was more suitable for the growth of 1-cyanoada- mantane single crystal.
