  nature of catechol derivatives. The observed homogeneous rate constants of the reactions were estimated by fitting the absorption time profiles for each reaction. The effect of β-cyclodextrin and its inclusion complex has also been studied on the chosen reactions. The formation constants of the complexes of catechol, dopamine and epinephrine with β-cyclodextrin as well as the rate constants of the reactions

  在不存在和存在N-甲基苯胺的条件下，通过UV-Vis研究了儿茶酚，多巴胺和肾上腺素的氧化反应。分光光度法。根据儿茶酚衍生物的性质，已经观察到了该氧化所伴随的多种反应途径（分子间和分子内反应）。通过拟合每个反应的吸收时间曲线来估计观察到的反应的均相速率常数。还对所选反应研究了β-环糊精及其包合物的作用。通过将吸收时间光谱拟合到所提出的动力学平衡模型，获得了儿茶酚，多巴胺和肾上腺素与β-环糊精的配合物的形成常数以及游离和络合形式的反应的速率常数。
