Reaction Kinetics of N-Chlorination of Bis-(2,4,6-Trichlorophenyl)-Urea to N,N′-Dichlorobis-(2,4,6-Trichlorophenyl)-Urea by Hypochlorous Acid

摘要

References(20) 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, Ea = 39.7456 kJ mol–1 and the frequency factor, ko = 1.49554 × 106 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.
