Kinetic investigation on liquid–liquid–solid phase transfer catalyzed synthesis of dibenzyl disulfide with H2S-laden monoethanolamine

Journal of Molecular Catalysis A: Chemical, 2016

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 H 2 S -laden gas for production of a value-added fine chemical.

Utilization of Hydrogen Sulphide for the Synthesis of Dibenzyl Sulphide : Effects of Process Parameters on Conversion and Selectivity

Dibenzyl sulphide (DBS) was synthesized by the reaction between benzyl chloride and aqueous ammon... more Dibenzyl sulphide (DBS) was synthesized by the reaction between benzyl chloride and aqueous ammonium sulphide using tetrabutylammonium bromide (TBAB) as phase transfer catalyst (PTC). Benzyl mercaptan (BM) was identified in the reaction mixture as the secondary product. The selectivity of DBS, was maximized by changing various parameters such as stirring speed, temperature, catalyst loading, concentration of benzyl chloride and NH3/H2S mole ratio. The highest selectivity of DBS obtained was about 90% after 445 minutes of reaction with excess benzyl chloride at 333 K. Complete conversion of benzyl chloride could be achieved at the cost of very low selectivity of DBS and very high selectivity of BM. The apparent activation energy for the kinetically controlled reaction was found to be 174.4 kJ/mol.

Tri-liquid phase transfer catalysis: A green reaction technology

Chemical industries, which are the heart of today's technological development of the society,... more Chemical industries, which are the heart of today's technological development of the society, are a major cause of concern for the ever-growing environmental degradation due to harmful waste generation. The importance of waste reduction and reuse is therefore paramount. Also, it is better to minimize waste during a reaction than to go for an expensive treatment and/or recovery process after the reaction. Multiphase reactions are frequent in most chemical processes in industries and phase transfer catalysis has already been proven as an effective remedy in enhancing selectivity and yield of desired products. A reusable catalyst-rich phase in the bi-liquid phase reaction is an attractive option because, along with a higher rate of reaction and better selectivity, it can be reused several times, thereby leading to cost-effectiveness. We review here several examples of industrially important reactions involving nucleophilic substitution, etherification, oxidation/reduction, esterifi...
