摘要
新支持 IL 的 diol, 1-(2,3-dihydroxypropyl )-3-methylimidazolium hexafluorophosphate 被英尺红外, 1H NMR, 13C NMR 和 MS (ESI ) 综合了并且描绘。它象冻结点,溶解度和比重和热稳定性那样的物理性质是坚定的。为醛的一个保护的组也被调查的结果的 diol 的合成实用程序。
A new IL-supported diol, 1-(2,3-dihydroxypropyl)-3-methylimidazolium hexafluorophosphate has been synthesized and characterized by Fr-IR, ^1H NMR, ^13C NMR and MS (ESI). Its physical properties such as freezing point, solubility and specific gravity and thermal stability were determined. Synthetic utilities of the resultant diol as a protecting group for aldehydes were also investigated.
