摘要: 采用溶剂萃取法对β-环糊精水溶液反应体系中的β-环糊精进行了回收,发现:β-环糊精与反应体系中的有机物可形成包结物;不同有机溶剂和不同组成的混和溶剂对β-坏糊精的回收率有较大影响,丙醇/水体积比为2: 1 时,β-环糊精的回收率达959毛;有机溶剂对β-环糊精水溶液反应体系中的有机物表现出不同的萃取效果;对苯甲醇和苯甲酶体系而言,乙酸乙醋是较好的萃取剂,对苯甲醇和苯甲酶的回收率可达到99%毛以上,可用于这两种有机物的快速定量.

Abstract:

The recovery of β-cyclodextrin from an aqueous reaction system was carried out by means of solvent ex-traction. It is found that (1) there exists an inclusion complex of β-cyclodextrin with organic compounds in the re-action system; (2) the recoveηof β-cyclodextrin is greatly influenced by the variety of organic solvents and the composition of the mixed solvents , reaching 95% when the ratio of acetone to water is 2: 1 ( volume ratio) ; (3) the extraction is significantly affected by the variety of organic solvents; and (4) in the aqueous β-cyclodextrin solution containing benzyl alcohol and benzaldehyde , ethyl acetate is a good choice to the quick quantitive determination of benzyl alcohol or benzaldehyde , with an extraction of more than 99%.
