Abstract

This thesis work engages the study of treatment of hydrogen sulphide gas based on phase transfer catalysis for the production of DiBenzyl Sulphide and other organic sulphides at room temperature and optimizing the conditions for 100% selectivity and maximum conversion. This study focuses on the condition optimization for preparation of Dibenzyl sulphide and also maximum absorption of H2S on cheaper solvents. Benzyl chloride was used as the reactant and MethylEthylAmine (MEA) for absorption of H2S gas. Phase transfer catalyst chosen was PEG-400 for its non-pollutant nature and cost of course. Toluene was made the organic Solvent. The amount of catalyst required was around 0.12wt% because of its low reactivity. The optimum time was around 7-8 hrs and the sulphide concentration for DBS formation was 1.646 kmol/m3 at a temperature of 60ºC. The experiments were done using one variable at a time approach as it was a simple system.
