Kinetics studies in synthesis of dibenzyl sulphide in liquid-liquid-solid mode

Kumar, Akash (2013) Kinetics studies in synthesis of dibenzyl sulphide in liquid-liquid-solid mode. BTech thesis.



As high quality of crude reserves are depleting and what we are left with high sulphur crude there is a strong need for some process which can effectively and economically remove sulphur from the process otherwise it may lead to unwanted side reactions which would entail consumption of reactants and energy. Usually the sulphur is removed by absorption in ammonia solution which is further processed in a Claus Unit to produce elemental sulphur which requires a high amount of energy. With a view to making more sophisticated fine chemicals which have higher usability and better market value, this project was undertaken to study the kinetics of the synthesis of dibenzyl sulphide was carried out using hydrogen sulphide rich monoethanolamine under tri phase transfer catalysis with a phase transfer catalyst (PTC). The Amberlite IR400 has been chosen the phase transfer catalyst as it is solid and can be reused. Parametric studies of the reaction between benzyl chloride in presence of organic solvent and H2S rich MEA were done in this work and it is tried to determine what type of conditions favor the more conversion of benzyl chloride and more synthesis of dibenzyl sulphide.
