the catalytic oxidation of toluene to benzoic acid in the liquid phase has been studied in an un-stirred tank reactor. low concentration of acetic acid was added in order to increase the solubility of the catalyst in toluene. the dependence of the rate of reaction on the concentration of toluene catalyst and oxygen pressure was studied. it has been suggested that liquid phase oxidation of tolue...

background: paradoxical reactions to benzodiazepines including restlessness, anxiety and sometimes violent behavior sometimes occur. most of the known predicting factors of disinhibitory reactions such as age, gender, genetic or the psychological backgroundare not modifi able. th is study was conducted to evaluate the eff ect of rate of midazolam administration, as a controllable factor, on the...

in this study, the stability of trinitroglycerin (tng) in polyethylene (peg) 400 was investigated according to arrhenius approach. the reaction rate constant (k) for the thermal disintegration of tng in peg 400 at various temperatures was counted based on the percents of remaining tng at different intervals of time at a specific temperature. the results showed that “k” at 40, 50, 60, 70, 80 and...

Chemical reaction rate and diffusion rate were defined. The concomitant advances in theory, measuring systems and computer simulation bring the new perspectives to the chemical reaction with diffusion studying. The obtained results shows effect the chemical reaction rate and diffusion. The obtained results demonstrate characterization of the dynamic and steady state conditions of the chemical s...
