- Preparation method of thiophosphoric acid tri (4-aminobenzene) ester
-
The invention relates to a preparation method of thiophosphoric acid tri (4-aminobenzene) ester. Specifically, according to the preparation method of the thiophosphoric acid tris (4-aminobenzene) ester, acetaminophen and thiophosphoryl chloride are used as raw materials, and esterification and hydrolysis reactions are performed in sequence to obtain the thiophosphoric acid tris (4-aminobenzene) ester. The synthesis method of thiophosphate tri (4-aminobenzene) ester has the advantages of short synthesis route, simple process operation, mild reaction conditions, short reaction time, fast reaction speed, strong selectivity, high yield, high purity, low cost, avoidance of expensive and highly toxic reagents and catalysts, environmental protection and easy industrial production.
