| Abstract: | The high purity dimethyl disulfide(DMDS) was prepared.The technological process of the reactions was described.The suitable technological conditions of the reactions and unit operations were established based on the experiment results. The optimum reaction conditions of synthetizing DMDS from Na2S2 and (CH3)2SO4 are as follows: the molar ratio of Na2S2 to (CH3)2SO4 is 1.2；the reaction temperature is controlled between 50～55 ℃；the reaction time is 2.0～2.5 h；the volumetric flow rate is 30～35 mL/min.The total yield of DMDS reached more than 92% and its purity is over 99.7%. |
