摘要：

The adduct of Al(NO3)(3) . 6CO(NH2)(2) has been prepared and characterized by means of chemical analysis, IR spectroscopy, X-ray patterns and microscopy. A thermoanalytical study of Al(NO3)(3) . 6CO(NH2)(2) as well as urea, for comparison purposes, under conventional dynamic and quasi-isothermal - quasi-isobaric conditions in air has been carried out. It has been found that the adduct is thermally stable up to about 200 degrees C, i.e. up to higher temperature than the decomposition temperature of the constituent compounds. The thermal decomposition mechanism of the adduct is complex, thus infrared spectroscopy and X-ray diffraction techniques have been used to determine the intermediate products. Aluminium oxide(III) is the final decomposition product.
