The kinetic of oxidation of thiourea with N-bromosuccinimide (NBS) has been studied The oxidation reaction is kinetically of the second order, being first order with respect to both thiourea and NBS. The rate increases with increase of pH and decrease of dielectric constant of the medium The addition of NaCI and NaNO₃, electrolytes to the reaction mixture shows negative salt effect.
