Thermal decomposition process of four benzimidazolyl-containing dicopper(Ⅰ) complexes: [Cu2(OCTB)](ClO4)2·1.5H2O(1), [Cu2 (NMOCTB)](ClO4)2·H2O(2),[Cu2(NBUOCTB)](ClO4)2(3), [Cu2(NBOCTB)](ClO4)2·H2O(4) a...Thermal decomposition process of four benzimidazolyl-containing dicopper(Ⅰ) complexes: [Cu2(OCTB)](ClO4)2·1.5H2O(1), [Cu2 (NMOCTB)](ClO4)2·H2O(2),[Cu2(NBUOCTB)](ClO4)2(3), [Cu2(NBOCTB)](ClO4)2·H2O(4) and their kinetics were studied under the non-isothermal conditions by TG-DTG techniques. The non-isothermal kinetic data were analyzed by means of Achar and Coats-Redfern method respectively.The kinetic equation for the second step of the decomposition of complex (1) can be expressed as: dα/dt==A.exp(-E/RT).(1-α), the mechanism of this reaction corresponds to "Coring and Growth" with n=1; while for the first step of complex (3) decomposition, dα/dt=A·exp(-E/RT)·.(1-α)2, which corresponds to the mechanism of "the second-order chemical reartion".展开更多

The complexes were characterized by elemental analysis, IR and 1H NMR measurements. Bioactivity tests showed that the complexes inhibited the cucumber mosaic virus. Among them the best effective was glycine salicylaldehyde Schiffbase Ag(Ⅰ), which gave the effective level up to 74.7% towards CMV in dosage of 400 mg/L(in case of phaseolus vulgarisl inoculation).展开更多
