摘要：

Fourier transform infrared spectroscopy has demonstrated that hydrogen bonds are responsible for the aggregation of 1,2-O-(1-ethylpropylidene)-alpha-D-glucofuranose molecules in solid and benzene gels. The thermal stability of the studied gel is described by its melting temperature T-GS and thermal parameters. The deduced value of the gel-sol transition enthalpy is 50 kJ/mol. Viscosity is the major factor which influences the dynamics of the benzene molecules in the gels, as proved by the relaxation measurements. (C) 2008 Elsevier Ltd. All rights reserved.
