Diphenyl chlorophosphate Chemical Properties,Uses,Production

Description

Diphenyl chlorophosphite is a viscous colorless liquid. It can be prepared in situ by the reaction between diphenyl hydrogen phosphonate and carbon tetrachloride. It is used to prepare aromatic polyesters by polycondensation reaction in pyridine and polyesteramide. Diphenyl chlorophosphite is used as a phosphonating agent, such as to prepare phenylphosphonic acid.

Uses

Diphenylacetonitrile can be used to synthesize methadone, an opioid used for opioid maintenance therapy and for pain relief. It is used to control seedling grasses in turf. It undergoes anhydrous condensation with ethyl-4-bromo-butyrate and the hydrolysis product in alkaline medium of this condensation reaction is used in the quantitative determination of 3-cyano-3,3-diphenylpropionic acid.

General Description

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.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

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.

Health Hazard

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.

Fire Hazard

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.]
