摘　　要：A new complex of Copper（Ⅱ） has been synthesized and characterized by elemental analysis,IR,UV and electrical conducivity.The non-isothermal kinetics of the thermal decomposition of complex under dynamic air atmosphere was studied by TG-DTG technique.The results show that Copper（Ⅱ） complex of 2,4-dihydroxydiphenylmethone have a metal-ligand ratio of 1:2 and the ligand between metal ion coordinates through oxygen atom of-C=O and next to-OH group.Mathematical analysis of TG-DTG data using the integral methods and differential method show that the first step thermal decomposition of complex is controlled by Mampel Power,f（α）=1,with E of about 165.69 kJ/mol and A equates 6.384×1014S-1.A new complex of Copper （Ⅱ） has been synthesized and characterized by elemental analysis, IR, UV and electrical conducivity.
