A process for the production of carboxylic acids and their derivatives comprising the steps of: (c) reacting a derivative of an unsaturated fatty acid with an oxidizing compound in the presence of a catalyst capable of catalysing the reaction of oxidation of the double olefinic bond of the derivative of the unsaturated fatty acid so as to obtain as intermediate product of reaction a vicinal diol; and (d) reacting said intermediate compound with oxygen, or a compound containing oxygen, in the presence of a catalyst capable of catalysing the reaction of oxidation of the hydroxyl groups of the vicinal diol to carboxylic groups, characterized in that both of the steps (a) and (b) are carried out in the absence of added organic solvent and in that the water/diol ratio in the reaction of step (b) is less than 1:1.
一种生产羧酸及其衍生物的方法,包括以下步骤:(c)在催化剂的存在下,将不饱和脂肪酸衍生物与氧化剂反应,催化剂能够催化不饱和脂肪酸衍生物的双烯键氧化反应,从而得到邻二醇的中间产物;(d)在催化剂的存在下,将该中间化合物与氧气或含氧化合物反应,催化剂能够催化邻二醇的羟基氧化反应成为羧基,其特征在于步骤(a)和(b)都在无添加有机溶剂的情况下进行,并且步骤(b)中的水/二醇比小于1:1。
