摘要

Abstract

Insoluble β-cyclodextrin polymers were prepared from β-cyclodextrin(β-CD) using epichlorohydrin(EPI) as crosslinking agent under basic conditions.The polymers were characterized by Fourier Transform Infrared(FTIR)

Thermogravimetry(TG)

X-ray diffraction(XRD) and TG-FTIR.The results demonstrated that the polym-erization between EPI and β-CD indeed occurred

and a number of CD rings were interconnected to form a three-dimensional network.Moreover

different factors influencing the polymerization

e.g.

molar ratio of EPI to β-CD

the concentration of NaOH and reaction temperature

have been investigated.The polymer prepared under the optimal conditions(the molar ratio EPI:β-CD of 44

the NaOH concentration 50% in mass

and the temperature at 65℃) showed excellent thermal stability and insolubility in organic solvents or strong acid/base.In addition

the β-cyclodextrin polymers also presented high catalytic activity for aqueous oxidation of benzyl alcohol with hy-pochlorite as oxidant.
