摘　　要：用薄层和半无限扩散紫外—可见光谱法研究了铂片对溶液中苯胺类化合物的催化现象，测定了铂催化对氨基苯酚氧化反应及其随后不可逆均相水解反应的速率常数，实验结果表明：铂催化对氨基苯酚氧化反应与极化条件下发生的反应中间产物及最终水解产物完全相同，催化反应速率较快，速率常数为１０－２数量级。The platinum catalyzing reacting of compound for amino benzens was studied by the thin layer and the semi infinte diffusion UV visible spectra methods.The rate constants of the catalytic and hydrolysis reaction of p aminophenol at different acid were determined.The experimental results indicated that the reactive product of the platinum catalyzing oxiditive and hydrolytic of p aminophenol is same as the product of the polarization condition.The rate of catalyzing reaction is quicker.The rate constants were calculated to be 10 -2 order of magnitude.
