A method of preparing cblorocyclohexane

The present invention relates to a process for preparing chlorinated cyclohexane. The technical scheme is: saturated sodium chloride solution as the electrolyte disposed in a stirred cell, adding a catalyst, an emulsifier, a mixture of three aqueous phase reaction solution, followed by addition of cyclohexane as an oil phase feed , dried at a temperature of 20 ~ 60 ℃ oil in water emulsion formed was stirred while 4 ~ 7V the electrochemical reaction in 0.5 ~ 3.5h the cell voltage was; Finally, 1.5 ~ 5mL water emulsion broken in the reaction, emulsions as methanol or ethanol, to give after breaking the oil phase is a mixture of cyclohexane and chlorocyclohexane product, the mixture is a distillation column a, distillation at a temperature of 85 ~ 95 ℃, ring light fraction is unreacted hexane, input cell recycling, the heavy fraction is cblorocyclohexane product purity of 99% or more refined distillation; aqueous phase after demulsification distillation column B, distillation at a temperature of 65 ~ 82 ℃ the light fraction is demulsifier methanol or ethanol, recovered and recycled.
