in this paper, macrocyclic cobalt(ii) complexes [col1](no3)2.4h2o (1) and [col2](no3)2.2h2o (2) have been synthesized from the reaction of dialdehydes 1,2-bis(2-formylphenyl)ethane and 1,3-bis(2-formylphenyl)propane, co(no3)2.6h2o and 1,2-cyclohexanediamine with molar ration 1:1:1 in methanole and characterized by elemental analyses and ft-ir spectroscopy. then used as precursors for preparatio...

in the current study, synthesis and characterization of a new nano-structured zirconium(iv)-minoxidil complex (1), where minoxidil, (c9h15n5o; 6-(1-piperidinyl)-2,4-pyrimidinediamine 3-oxide), have been investigated in two different solvents. the compound 1 has been synthesized by sonochemical method in the presence of methanol and monoethylene glycol (meg) as solvents and characterized by scan...

Pyrolysis essentially is the thermal decomposition of organic matter under inert atmospheric conditions or in a limited supply of air, leading to the release of volatiles and formation of char. Modeling of pyrolysis implies the representation of the chemical and physical phenomena in a mathematical form. In this study, Differential Evolution (DE) algorithm is applied and global optimum set of k...

The thermal decomposition reaction of acetone cyclic diperoxide (ACDP) in 1-octanol (OCT) solution, at the temperatures and initial concentration ranges of 130° -166 oC and (0.94-3.00) x 10 mol/L , respectively, follows a pseudo-first order kinetic law. Acetone is the main organic decomposition product observed. The activation parameters values of the initial reaction step (ΔH = 25.8 ± 0.3 kcal...

Chemiluminescence, Dioxetanes, Reaction Kinetics, Spectra, Biradicals The thermal decomposition of 1,2-diadamantyldioxetane was studied by kinetic and spectroscopic methods. Spectra of the chemiluminescence emitted during the thermally induced decomposition of 1,2-diadamantyldioxetane, tetramethyldioxetane and trimethyldioxetane were obtained and the influence of quenchers and radical-scavenger...
