Zhang, Jianfeng published the artcilePreparation and acidic dissociation constants determination of phenylenedioxybis(acetic acid), Product Details of C10H10O6, the publication is Huaxue Shijie (2002), 43(3), 135-137, database is CAplus.
Three types of phenylenedioxybis(acetic acid) were prepared by reacting dihydroxybenzene with chloroacetic acid in an alkali solution Controlling the pH value of the reaction system and applying a new self-sealing apparatus, high yield and selectivity were obtained. The acid dissociation constants of the samples were obtained for the first time by elec. potential titration A regression method was adopted in the data processing, which made the results more precise and reliable. CNDO/2 quantum chem. calculation method was used to explain the results of acid dissociation constant measurements.
