提出了一种利用挥发性烃制备环糊精沉淀的方法。在将液态或固态烃的蒸气引入水溶液中的α-、β-或γ-CyD中并使其在封闭系统中循环时，CyD可以容易地沉淀。分析从水溶液中分离的CyD沉淀物的烃/CyD摩尔比。还测量了上清液水溶液中CyD的浓度。该技术已在25 ℃下应用于正构烷烃（C5至C10）、环己烷、卤代苯（氟苯、氯苯、溴苯和碘苯）、对二氟苯、苯、萘、联苯和二苯基甲烷等烃类。还在β-CyD溶液中用C5-C8混合物的蒸气以各种混合比制备了氢化物。
A technique is proposed to prepare cyclodextrin (CyD) precipitates with volatile hydrocarbons. On introducing the vapor of a liquid or solid hydrocarbon into alpha-, beta-, or gamma-CyD in an aqueous solution and circulating it in a closed system, CyD can be easily precipitated. The CyD precipitates isolated from aqueous solutions were analyzed for the hydrocarbon/CyD molar ratio. The concentration of CyD in the supernatant aqueous solution was also measured. The technique has been applied at 25-degrees-C to such hydrocarbons as n-alkanes (C5 to C10), cyclohexane, halobenzenes(fluoro-, chloro-, bromo-, and iodo-benzene), p-difluorobenzene, benzene, naphthalene, biphenyl, and diphenylmethane. Precipitates were also prepared in beta-CyD solutions with the vapor of C5-Cg mixtures at various mixing ratios.
