1,2- O-(1-Ethylpropylidene)-α- d-glucofuranose, a low molecular mass organogelator: benzene gel formation and their thermal stabilities

Abstract

Fourier transform infrared spectroscopy has demonstrated that hydrogen bonds are responsible for the aggregation of 1,2- O-(1-ethylpropylidene)-α- 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.
