On the reversible protonation of acrylic-type compounds

On the reversible protonation of acrylic-type compounds The pseudo-first-order protonation rate coefficients of radical anions of acrylic-type monomers (produced by pulse radiolysis in aqueous acidic solutions) were found to be linearly dependent on the H3O+ concentration with second order rate coefficients of several times 1010 mol-1 dm3 s-1. The rate coefficients showed little structure dependence. On the contrary the equilibrium constants of protonation and therefore also the rate coefficients of deprotonation showed several orders of magnitude dependence on the anion structure.

Abstract

The pseudo-first-order protonation rate coefficients of radical anions of acrylic-type monomers (produced by pulse radiolysis in aqueous acidic solutions) were found to be linearly dependent on the H3O+ concentration with second order rate coefficients of several times 1010 mol-1 dm3 s-1. The rate coefficients showed little structure dependence. On the contrary the equilibrium constants of protonation and therefore also the rate coefficients of deprotonation showed several orders of magnitude dependence on the anion structure. In the paper this structure dependence is discussed.
