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.

含H ₂ S的单乙醇胺液-液相-固相​​转移催化合成二苄基二硫的动力学研究

已经进行了关于使用H ₂ S进行合成的研究，其中使用Amberlite IR-400作为相转移催化剂来合成二苄基二硫化物（DBDS）。这涉及在单乙醇胺水溶液（MEA）中吸收H ₂ S，然后使这种含H ₂ S的MEA与有机反应物苄基氯（BC）反应，在液-液-固（L–L–S）相转移下产生DBDS催化条件。研究了各种参数对BC转化率的影响，在某些工艺参数水平下，所需产物的选择性为100％。已经提出了合适的反应机理，并建立了数学模型来解释反应的动力学。因此，废物的最小化受到H ₂的利用的影响SH2S-载气，用于生产增值精细化学品。
