    • The invention relates to a process for the preparation of azelaic acid or alkyl azelate starting from mono-unsaturated 9-octadecenedioic acid or its corresponding alkylester characterized in that the process comprises at least the following step: reacting the mono-unsaturated 9-octadecene dioic acid or its corresponding alkylester with hydrogen peroxide in the presence of an organic carboxylic acid other than 9-octadecene dioic acid and a suitable catalyst to effect cleavage of the double bond in the mono-unsaturated 9-octadecene dioic acid or its corresponding alkylester. The invention further relates to the azelaic acid or alkyl azelate obtainable by the process according to the invention and to the use of azelaic acid or alkyl azelate or monomers derived there from for the preparation of a polymer, especially a polyamide.
    • 本发明涉及从单不饱和9-十八烯二酸或其相应的烷基酯开始制备壬二酸或壬二酸烷基酯的方法,其特征在于该方法至少包括以下步骤:使单不饱和9-十八烯二酸 或其相应的烷基酯与过氧化氢在除9-十八烯二酸之外的有机羧酸和合适的催化剂存在下进行,以实现单不饱和9-十八烯二酸或其相应的烷基酯中双键的切割。 本发明还涉及通过本发明的方法获得的壬二酸或壬基壬磺酸烷基酯,以及由壬二酸或壬二酸烷基酯衍生的单体或其衍生物用于制备聚合物,特别是聚酰胺的用途。

    • The present invention provides a safe, convenient and efficient method for producing carboxylic acid by a reaction of alicyclic alcohol with an aqueous hydrogen peroxide to thereby obtain carboxylic acid in high yield from alicyclic alcohol or alicyclic ketone under mild reaction conditions, wherein the reaction operation is simple and easy, a step for removing solvent after completion of the reaction is not necessary and influence and toxicity upon the environment and human body are markedly small. In order to provide it, an oily alicyclic alcohol is allowed to react with an aqueous hydrogen peroxide in the presence of a catalyst containing a metal compound belonging to Group 6 of the Periodic Table in a heterogeneous solution system.
    • 本发明提供一种通过脂环醇与过氧化氢水溶液的反应制备羧酸的安全,方便和有效的方法,从而在温和的反应条件下从脂环族醇或脂环族酮得到高产率的羧酸,其中反应操作是 简单易行,不需要在反应完成后除去溶剂的步骤,对环境和人体的影响和毒性明显较小。 为了提供它,使油性脂环醇在含有属于元素周期表第6族的金属化合物的催化剂的存在下在过氧化氢水溶液的异构溶液体系中反应。
