Diphenyl chlorophosphate

디펜닐포소릴클로라이드 C화학적 특성, 용도, 생산

용도

Diphenyl chlorophosphate is used to prepare cyclohexyl-amidophosphoric acid diphenyl ester by reacting with cyclohexylamine. It is also used in the synthesis of alfa-substituted beta-lactams, anhydrides, esters and thioesters. It is also employed in the conversion of aldoximes to nitriles. Further, it is used in the preparation and reaction of enol phosphates, guanosine-adenosine-5',5'-triphosphate, guanosine-cytidine-5',5'-triphosphate, guanosine-uridine-5',5'-triphosphate, diguanosine-5',5'-diphosphate and diguanosine-5',5'-triphosphate. In addition to this, it serves as a phosphorylating agent for the preparation of 2-deoxy-D-galactose-3 and -6 phosphoric acids.

제조 방법

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%.

일반 설명

A clear colorless to light yellow liquid with a pungent odor. Insoluble in water and denser than water. Hence sinks in water. Contact may severely irritate skin, eyes and mucous membranes. Flash point above 235°F.

공기와 물의 반응

Insoluble in water.

반응 프로필

Diphenyl chlorophosphate is incompatible with bases (including amines) strong oxidizing agents, and alcohols. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291]. May form highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.

건강위험

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

화재위험

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

Purification Methods

Fractionally distil it in 30 351.5490. a good vacuum; better use a spinning band column. [Walsh J Am Chem Soc 81 3023 1959, IR: Bellamy & Beecher J Chem Soc 475 1952, Beilstein 6 IV 737.]
