| Hazard Information | Back Directory | [General Description]
A colorless, fuming liquid. Density 1.32 g/cm3. Flash point 102°C. Corrosive to metals and tissue. | [Reactivity Profile]
BENZENE PHOSPHORUS DICHLORIDE(644-97-3) is incompatible with water, with bases (including amines), with strong oxidizing agents, and with 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]. | [Air & Water Reactions]
Reacts with water, including moisture in air or soil, to liberate heat and hydrochloric acid [Merck, 11th ed. 1989]. | [Hazard]
Highly corrosive to skin, tissue. Flammable. | [Health Hazard]
Inhalation causes irritation of nose and throat; pulmonary edema may develop following severe exposures. Contact with skin or eyes causes severe burns. Ingestion causes severe burns of mouth and stomach. | [Chemical Properties]
Colorless to light yellow liqui | [Flammability and Explosibility]
Nonflammable | [Purification Methods]
Distil it in a vacuum byfractionating through a 20cm column packed with glass helices (better use a spinning band column) [Buchner & Lockhart J Am Chem Soc 73 755 1951, NMR: Müller et al. J Am Chem Soc 78 3557 1956, IR: Daasch & Smith Anal Chem 23 853 1951]. It forms a yellow Ni complex: Ni(C6H5Cl2P)4 (m 91-92o, from H2O) [Quin J Am Chem Soc 79 3681 1957 ] and a yellow complex with molybdenum carbonyl: Mo(CO)3.(C6H5Cl2P)3 (m 106-110o dec) [Abel et al. J Chem Soc 2323 1959]. [Beilstein 16 IV 972.] |
