摘要： A process for preparing dicarboxylic acids is described. More particularly a process is described for preparing adipic acid (1,6-hexanedioic acid), by the action of nitric acid, starting from cyclic ketones or alcohols which are the corresponding compounds from the standpoint of the number of carbon atoms, in the presence of one or more oxides of nitrogen at a molar concentration in the reaction mixture of greater than 2.5 mmol per kg of reaction mixture.
摘要翻译： 描述了制备二羧酸的方法。 更具体地描述了一种通过硝酸的作用制备己二酸（1,6-己二酸）的方法，该方法是在存在碳原子数的情况下，从作为相应化合物的环状酮或醇开始 的一种或多种氮氧化物，其反应混合物中摩尔浓度大于2.5mmol / kg反应混合物。

摘要： A process for preparing a deperoxidation catalyst comprising chromium as the main catalytic element is described. Also described, is a process for preparing an organic solution of a chromic acid ester. The solution can be used as a catalyst in a deperoxidation of an alkyl peroxide in a process for manufacturing cyclohexanol/cyclohexanone by oxidation of cyclohexane.
