  The present invention relates to a method for preparing carboxylic acids, in particular mono- and dicarboxylic acids, by oxidative cleavage of a vicinal diol. According to the invention, said method consists of reacting a vicinal diol of formula I: where: p is an integer comprised between 1 and 6; R1 and R2 are, separately: an alkyl or hydroxyl group having 1 to 12 carbon atoms; a —(CH 2 ) n —C0 2 M group where n, which can be identical or different in R1 and R2, is an integer comprised between 1 and 11 and M is a hydrogen atom or an alkyl group having 1 to 4 carbon atoms or an alkaline cation; or R1 and R2 jointly form an alkylene —(CH 2 )m- group where m is an integer comprised between 2 and 10, preferably between 2 and 6; with industrial-grade sodium hypochlorite (or bleach), in the absence of an organic solvent and without adding a catalyst, preferably at room temperature. The invention can be used for recycling natural vegetable oils.

  本发明涉及一种制备羧酸的方法，特别是通过对邻二醇进行氧化裂解制备单羧酸和二羧酸。 根据本发明，所述方法包括将式I的邻二醇进行反应： 其中： p是介于1和6之间的整数； R1和R2分别是： 具有1至12个碳原子的烷基或羟基基团； 一个—(CH 2 ) n —C0 2 M基团，其中n在R1和R2中可以相同也可以不同，是介于1和11之间的整数，M是氢原子或具有1至4个碳原子的烷基基团或碱性阳离子； 或者R1和R2共同形成一个亚烷基—(CH 2 )m-基团，其中m是介于2和10之间的整数，优选在2和6之间； 使用工业级次氯酸钠（或漂白剂），在无机溶剂的情况下且不添加催化剂的情况下，最好在室温下进行。该发明可用于回收天然植物油。
