Abstract

The pH-independent hydrolysis of bis (2, 4-dinitrophenyl) carbonate, DNPC, in aqueous acetonitrile was studied spectrophotometrically from 20 to 45° C. The binary solvent composition covers [H2O] from 0.02 to 51.39 M, corresponding to the water mole fraction, ξw, from 0.100 to 0.971. The dependence of log (k obs), the observed rate constant, on ξw is sigmoidal and is similar to the dependence of the solvent polarity scale ET (30) on ξw for ...
