147 ETHYLBENZENE 4. CHEMICAL AND PHYSICAL INFORMATION 4.1 CHEMICAL IDENTITY

Ethylbenzene is an aromatic hydrocarbon that occurs naturally in petroleum and is a component of aviation and automotive fuels. It is used as a solvent and in the production of synthetic rubber and styrene. Information regarding the chemical identity of ethylbenzene is located in Table 4-1. 4.2 PHYSICAL AND CHEMICAL PROPERTIES Ethylbenzene is a colorless liquid with an aromatic odor. Information regarding the physical and chemical properties of ethylbenzene is located in Table 4-2. Ethylbenzene is a flammable and combustible liquid. Vapors are heavier than air and may travel to a source of ignition and flash back. Liquid ethylbenzene floats on water and may travel to a source of ignition and spread fire. Combustion may produce irritants and toxic gases (HSDB 2009; NFPA 1994). Ethylbenzene may accumulate static electricity and will react with oxidizing materials (HSDB 2009; NFPA 1994)
