| Abstract | ||
| The research includes preparation ligand from Schiff bases (DMAB) [2,3 - Dimethyl -1-phenyl-4-(benzledene)-3-pyrozoline-5–one] derived from condensation reaction of 4-aminoantipyrene with benzaldehyde . The identity of this ligand and complexes have been characterized by spectral methods infrared ray (IR) and measured melting point (m.p.) . Complexes of ligand with Fe(III) as symbol (M1) and Cr(III) as symbol (M2) , were prepared. This work was carried out to study the thermal properties such as thermal conductivity, specific heat and thermal diffusivity behavior of compounds as a function of the raising of temperatures (303-328 K) , and the compounds have a low thermal conductivity and increases with increasing temperatures, as results show that the specific heat of the compounds prepared. However , the values of specific heat is increasing slightly higher temperatures, and the thermal diffusivity of this compounds is decreasing slightly with the higher temperatures as well , thermal analyses of compounds have been work by Differential Scanning Calorimeter(DSC) , phases have changed , and free matters have high thermal stability, complexed less matter stability, and compared the results with standard values. | ||
