| titleOfInvention | Method for preparing rubber peptizer DBD |
| abstract | The invention relates to a method for preparing a rubber auxiliary agent, and particularly discloses a method for preparing rubber peptizer 2,2-dibenzoylamino diphenyl disulphide (DBD). The method for preparing the rubber peptizer DBD is characterized by comprising the following steps of: performing ring opening reaction on benzothiazole to obtain a ring opening product; oxidizing the ring opening product to prepare diphenylamine disulphide; and performing acylation reaction on the diphenylamine disulphide and benzoyl chloride to generate the DBD. According to the method for preparing the rubber peptizer DBD, compared with the conventional process, the product cost is remarkably reduced; the method is favorable for popularization and application of the environmentally-friendly peptizer DBD, and simultaneously breaks through the situation that the product depends on import for a long term; the organic solvent is used as a reaction medium and can be recycled, so little three-waste is discharged; and the production flow is simple and easily controlled, high-temperature and high-pressure reaction does not exist in the method, the equipment investment is low, and the method is easy for production and operation. |
