benzene usage and synthesis |
chemical properties | colourless liquid |
general description | a clear colorless liquid with a petroleum-like odor. flash point less than 0°f. less dense than water and slightly soluble in water. hence floats on water. vapors are heavier than air. |
air & water reactions | highly flammable. slightly soluble in water. |
reactivity profile | benzene reacts vigorously with allyl chloride or other alkyl halides even at minus 70°c in the presence of ethyl aluminum dichloride or ethyl aluminum sesquichloride. explosions have been reported [nfpa 491m 1991]. ignites in contact with powdered chromic anhydride [mellor 11:235 1946-47]. incompatible with oxidizing agents such as nitric acid. mixtures with bromine trifluoride, bromine pentafluoride, iodine pentafluoride, iodine heptafluoride and other interhalogens can ignite upon heating [bretherick 5th ed. 1995]. benzene and cyanogen halides yield hcl as a byproduct (hagedorn, f. h. gelbke, and federal republic of germany. 2002. nitriles. in ullman encyclopedia of industrial chemistry. wiley-vch verlag gmbh & co. kgaa.). the reaction of benzene and trichloroacetonitrile evolves toxic chloroform and hcl gasses. (hagedorn, f., h.-p. gelbke, and federal republic of germany. 2002. nitriles. in ullman encyclopedia of industrial chemistry. wiley-vch verlag gmbh & co. kgaa.). |
health hazard | dizziness, excitation, pallor, followed by flushing, weakness, headache, breathlessness, chest constriction, nausea, and vomiting. coma and possible death. |
fire hazard | behavior in fire: vapor is heavier than air and may travel considerable distance to a source of ignition and flash back. |
