The invention belongs to the technical field of fine chemical engineering, and particularly relates to a system and a method for synthesizing rubber scorch retarder CTP. The system provided by the invention comprises a conveying pipeline for cyclohexyl sulfenyl chloride and catalyst mixed liquid, a conveying pipeline for phthalimide sodium salt and catalyst mixed liquid, and a micro-reaction device, wherein the micro-reaction device is respectively connected with the material outlet of the conveying pipeline for cyclohexyl sulfenyl chloride and catalyst mixed liquid and the material outlet ofthe conveying pipeline for phthalimide sodium salt and catalyst mixed liquid; the micro-reaction device is a microchannel reactor, a high-shear reactor or a pipe-type reactor. According to the systemprovided by the invention, liquid and liquid two-phase liquid is used for being in full contact in the micro-reaction device to react to synthesize the rubber scorch retarder CTP, the uninterrupted reaction of the CTP synthesi
