Product Name:Diphenyl chlorophosphate
CAS Number:2524-64-3
Molecular formula:C12H10ClO3P
Molecular Weight:268.63

The preparation of Diphenyl chlorophosphate is as follows:With a thermometer,Reflux condenser and mechanical agitation120 g of dichloromethane was placed in a 500 ml four-neck reaction flask.7.3 g of N,N-dimethylformamide,Stirring temperature control below 10 °C,Put 28g of bis(trichloromethyl) carbonate,A solution of 50 g of diphenyl phosphate and 120 g of dichloromethane was added.After the addition, the reaction was carried out for 3 hours. After the end of the reaction, the temperature was controlled below 10 ° C, 20 g of water was slowly added, and the mixture was stirred and the organic phase was dried over anhydrous sodium sulfate. The desiccant was removed by filtration, and the filtrate was evaporated under normal pressure. The temperature was lowered to 0 ° C, and the insoluble matter was removed by filtration to obtain 48.9 g of diphenyl chlorophosphate. The purity of GC was 99.2%, and the yield was 90.3%.
