| description | The method provides a method for continuously producing vulcanization accelerator TBBS by taking liquid chlorine as an oxidizing agent. The method comprises the following steps that a saline solutionof an accelerator MBT, tert-butylamine, an organic solvent and the liquid chlorine are introduced into reactors for an oxidation reaction, and a reaction product is post-treated to obtain a TBBS product; the reactors comprise a tubular reactor and/or a micro-channel reactor. The method for continuously producing the vulcanization accelerator MBT by taking the liquid chlorine as the oxidizing agenthas the advantages that the accelerator TBBS can be synthesized directly by taking crude MBT as a raw material, and the liquid chlorine is taken as the oxidizing agent for in-situ oxidation, which not only can avoid problem of large consumption of raw material lye and chlorine gas caused in the sodium hypochlorite production process, but also can effectively control the wastewater yield in the TBBS production process, and |
