Processes are disclosed for preparing carboxylic acids from organic esters, the processes comprising contacting an ester with water in the presence of an acid catalyst and a homogenizing solvent at conditions effective to form a carboxylic acid. The homogenizing solvent is present in an amount sufficient to form a single-phase reaction mixture comprising the ester, water, and homogenizing solvent. The homogenizing solvent may be selected from acetonitrile, dimethyl sulfoxide, and 1,4-dioxane.
公开了从有机酯制备羧酸的过程,该过程包括在酸催化剂和均相溶剂存在下将酯与水接触,以形成羧酸的有效条件。均相溶剂以足够量存在,以形成包括酯、水和均相溶剂的单相反应混合物。均相溶剂可以选择自乙腈、二甲基亚砜和1,4-二氧六环。
