The reaction kinetics of formation of N,N'-Dichlorobis-(2,4,6-trichlorophenyl)-urea (CC2) from bis(2,4,6-trichlorophenyl)urea (HCC) by N-chlorination using hypochlorous acid as chlorinating agent has been studied at various temperatures in a batch reactor. Experiments were carried out at different stoichiometric reactant ratios. Analysis of the experimental data by Integral method indicated that the reaction follows a second order kinetics. The effect of temperature on the reaction rate has been determined using Arrhenius equation. The graphical analysis yields an activation energy, E-a = 39.7456 kJ mol(-1) and the frequency factor, k(o) = 1.49554 x 10(6) L mol(-1) min(-1). The kinetic data obtained by this study will be of immense help to design engineers for designing a plant of industrial capacity.
