A method is provided for enhancing the production rate of arylhydroxylamines by moderated catalytic hydrogenation reactions. Small quantities of acid introduced to the reaction medium doubles the hydrogenation rate of nitroaromatic compounds without a significant loss in selectivity to arylhydroxylamines.
提供了一种通过缓和催化加氢反应提高芳基
羟胺生产率的方法。在反应介质中引入少量酸,可使硝基芳香族化合物的氢化速率提高一倍,而对芳基
羟胺的选择性不会显著降低。
