The kinetics of alkaline fading crystal violet (CV) has been studied by UV spectrophotometry and microcalorimetry in the critical binary solution 2-butoxyethanol + water at initial reaction stage various temperatures. It was found that first-order rate constants obtained from these two methods are well accorded with each other, temperature dependence constant obeyed Arrhenius equation a region far point. slowing down detected both near A simple empirical crossover model proposed used to...

We have used three-wavelength UV-spectrophotometry to study the reaction of alkaline fading phenolphthalein in critical solution 2-butoxyethanol + water. It was found that when temperature far away from point, values natural logarithm rate constant k and chemical equilibrium K determined our experiments had good linear relationships with reciprocal temperature, which served as backgrounds were for correcting region. The slowing down anomaly detected near point. value exponent characterizing...

Abstract A practical and efficient methodology for the synthesis of aromatic primary amides by reaction benzylic alcohols aqueous ammonia in presence an I 2 /TBHP system acetonitrile was developed. This oxidative amidation proceeded smoothly at ambient temperature tolerated a variety functional groups. wide range were obtained moderate to high yields. Preliminary kinetic studies possible mechanism also discussed.

The binding reaction of reduced graphene oxide-silver nanocomposites (rGO-AgNCs) with calf thymus single-stranded DNA (ssDNA) was studied by ultraviolet-visible absorption, fluorescence spectroscopy and circular dichroism (CD), using berberine hemisulphate (BR) dye as a probe. absorbance ssDNA increases, but the intensity is quenched addition rGO-AgNCs. rGO-AgNCs able to increase quenching effects BR ssDNA, induce changes in CD spectra. All evidence indicated that there relatively strong...

In this work, we studied the kinetics of oxidation iodide ion by persulfate in critical water/bis(2-ethylhexyl) sodium sulfosuccinate (AOT)/n-decane microemulsions with molar ratios water to AOT being 35.0 and 40.8 via microcalorimetry at various temperatures. It was found that Arrhenius equation valid for correlating experimental measurements noncritical region, but slowing down effect existed significantly near region. We determined values exponent it be 0.187 ± 0.023 0.193 0.032,...

Abstract The rate constants of two redox reactions and in the critical solution 2‐butoxyethanol water have been measured by using UV spectrophotometry at initial reaction stage. It was found that various temperatures for were well described Arrhenius equation noncritical region. slowing down effect detected exponents determined to be 0.044 ± 0.004 0.046 0.005 , respectively. values showed only dynamic effect, no thermodynamic singularity could observed reactions.
