Synthesis of dibenzyl sulphide by using PEG-6000 as a green catalyst

Abstract

Now a days Hydrogen Sulphide become a major pollutant for degradation of environment. So it is essential to remove this problem efficiently and effectively. The present project provides an alternative method to utilise the Hydrogen Sulphide to produce more economic, sophisticated product like Dibenzyl Sulphide and Benzyl Mercaptan. The whole process followed by the proper absorption of Hydrogen Sulphide in Monoethanolamine & then reacting the entire mixture with Benzyl Chloride to produce Dibenzyl Sulphide and Benzyl Mercaptan using Polyethylene Glycol 6000 as a phase transfer catalyst as the reaction involve two different phase. The main objective of this work is to maximize the conversion of Benzyl Chloride. It is also involve the analytical study of effect of different parameters like stirring speed, benzyl chloride concentration, sulphide concentration.
