Abstract:2,4-ditrichloromethyl-6-methyl-1,3,5-triazine(chloro-triazine), which was the intermediate of 2-methylamino-4-methoxyl-6-methyl-triazine, was synthesized from tritox through cyclization. The content is over 98%,and the yield is over 50%. The cost is redused 50% , and it is friendly to the circumstance. |
Key words:acetonitrile; chlorination; cyclization; chloro-triazine; triazine |
