| Abstract：1,1-bis(methylthio)-2-nitroethene was prepared by reacting nitromethane and carbon bisulfide.Effects of temperature,reaction time,methylating agent,solvent,molar ratio of nitromethane and carbon bisulfide on yield of 1,1-bis(methylthio)-2-nitroethane were discussed.The optimum operation conditions were as follow: the reaction temperature of 35 ℃,reaction time for 3.0 h.In the process of dimethyl sulfate methylation,the optimum operation condition was at the room temperature for 3.0 h.The yield was 84%.Crude... |
