description The invention discloses a method for continuously a synthesizing scorch retarder CTP intermediate (dicyclohexyl disulphide). The method includes the steps of mixing cyclohexene and a hydrochloric acidwater solution to have an addition reaction, washing a chlorocyclohexane coarse product phase obtained through the reaction with alkali liquor to obtain chlorocyclohexane, using a hydrochloric acid water solution obtained through layering for synthesizing a next batch of chlorocyclohexane, mixing chlorocyclohexane, sulphur, sodium sulphide and water to have a vulcanization reaction, conducting standing and layering on reaction liquid obtained after the reaction, distilling an obtained oil phase, sequentially obtaining a cyclohexene coarse product and dicyclohexyl disulphide, and directly using the obtained cyclohexene coarse product for raw material reusing. The cyclohexene coarse product can be used for production, the defects that an existing dicyclohexyl disulphide synthesizing processis complex, separating an
