•In all experimental run, selectivity of the product DBDS was 100%.•Reaction was kinetically controlled with activation energy 56.03 kJ/mol.•Anion exchange resin Amberlite IR-400 showed good reusability.•Developed kinetic model predicts the results quite well at all temperatures.•The proposed mechanism can successfully explain the course of the reaction.
An investigation has been done on the utilization of H2S for the synthesis of dibenzyl disulfide (DBDS) using Amberlite IR-400 as a phase transfer catalyst. This involves absorption of H2S in aqueous monoethanolamine (MEA) followed by reaction of this H2S-laden MEA with organic reactant benzyl chloride (BC) to yield DBDS under liquid–liquid–solid (L–L–S) phase transfer catalysis condition. The effect of various parameters on the conversion of BC was studied and the selectivity of desired product was 100% at some level of process parameters. A suitable reaction mechanism has been proposed and a mathematical model has been developed to explain the kinetics of the reaction. Waste minimization was therefore affected with the utilization of H2SH2S-laden gas for production of a value-added fine chemical.
