英文摘要: The surface of spherical magnesium oxide has been modified with ethylene glycol in the presence of basic aqueous solution. Fourier transform infrared spectra have shown the presence of the graft group ethylene glycol on the surface of spherical magnesium oxide. In addition, this conclusion can also be drawn from appearance of new diffraction peak in X-ray diffraction pattern. Although magnesium oxide microspheres can directly react with ethylene glycol in 373 K for 24 h, owing to Lewis acid and alkali interaction, product derived is colloidal and difficult to filter so that their morphology is easy to be destroyed, However, in the presence of basic aqueous solution. their morphology still retains. The modified magnesium oxide illustrates a specific surface area of 55.9 m(2)/g and a narrow pore size distribution centered at 8.96 nm. (C) 2009 Elsevier B.V. All rights reserved.
