Eberson, L.; Welinder, H. published the artcile< Cyclic anhydrides. III. Equilibrium constants for the acid-anhydride equilibrium in aqueous solutions of certain vicinal diacids>, Safety of 4-Bromoisobenzofuran-1,3-dione, the main research area is cyclic anhydrides equilibrium constant; acid anhydride equilibrium; vicinal diacids anhydrides equilibrium; succinic acid anhydrides equilibrium; alicyclic acid anhydrides equilibrium; maleic acid anhydrides equilibrium; phthalic acid anhydrides equilibrium.
Equilibrium constant were measured for the equilibrium diacid ⇌ anhydride + H2O in aqueous solutions of a number of vicinal diacids, chosen to correspond to relatively stable or very stable anhydrides. Such acids include di-, tri-, and tetraalkylsuccinic acids, certain alicyclic diacids, dialkylmaleic acids, and some alkyl-substituted phthalic acids. In all cases, the driving force for formation of a stable anhydride is relief of steric strain in the anhydride as compared to the corresponding diacid. Diisopropylmaleic anhydride was prepared as a new compound Low–melting 2,3-diethyl-2,3-dimethylsuccinic acid was shown to possess the dl-configuration by resolution.
Journal of the American Chemical Society published new progress about Anhydrides Role: PRP (Properties). 82-73-5 belongs to class bromides-buliding-blocks, and the molecular formula is C8H3BrO3, Safety of 4-Bromoisobenzofuran-1,3-dione.
