| titleOfInvention | A kind of trichloroacetone with high purity preparation process |
| abstract | The present invention relates to chemicals production technical field, specially a kind of trichloroacetone with high purity preparation process can relatively significantly improve the content of trichloroacetone in the crude product that one step of trichloroacetone produces, and improve product purity.Specifically include following steps：S1：Acetone is mixed with ethylene glycol, accelerating agent is added thereto, heats, stir evenly, carries out addition reaction；S2：It is passed through chlorine in the mixture prepared to S1, and catalyst is added, is stirred and evenly mixed, chlorination reaction is carried out；S3：Concentrated sulfuric acid hydrolysis is added in the mixture prepared to S2, prepares trichloroacetone crude product；S4：The trichloroacetone crude product prepared in S3 is purified for the first time with water；S5：Continued to carry out second of purification to trichloroacetone crude product with benzene；S6：Third time purification is carried out to trichloroacetone crude product with alcohol；S7：Product after S6 step process is recrystallized, trichloroacetone finished product is obtained. |
