Pseudo-first-order rate constants (k(obs)) for alkaline hydrolysis of N-benzylphthalimide (1) show a nonlinear decrease with the increase in [C,,,E,,]T (total concentration of Brij 58, m = 16, n = 20 and Brij 56, nt = 16, n = 10) at constant [CH3CN] and [NaOH]. These nonionic micellar effects, withi...
