Health hazard: The vapor is strongly irritating to the respiratory tract. Repeated and prolonged inhalation can cause lung, liver and kidney damage. Central nervous system suppression caused by high concentration inhalation can be fatal. Vapors are strongly irritating to the eyes, and liquids can cause eye burns. Direct skin contact with liquids can cause burns. Oral administration causes liver and kidney damage and can lead to death. Chronic poisoning: Chronic exposure to small amounts may result in neurasthenic syndrome and peripheral neuropathy.
Dangerous characteristics: the vapor and air form explosive mixture, in case of open fire, high temperature can cause decomposition explosion and combustion. In case of high heat can occur violent decomposition, causing container rupture or explosion accident. Combustion (decomposition) products: carbon monoxide, carbon dioxide, hydrogen chloride.

Toluene
Toluene is mainly made from crude oil through the petrochemical process. As a solvent it is used in oils, resins, natural rubber and synthetic rubber, coal tar, asphalt, cellulose acetate, as a solvent for cellulose paints and varnishes, as well as for photographic plate, ink solvent. Toluene is also the main raw material for organic synthesis, especially benzoyl chloride and phenyl, saccharin, trinitrotoluene and many dyes. It is also a component of aviation and automotive gasoline. Toluene is volatile and does not react well in the environment. It may eventually be degraded by biological and microbial oxidation because of its widespread distribution in the environment and its water-breaking recirculation between air and water by rain and evaporation from the water surface. A summary of average concentrations in the air of many cities around the world shows that toluene concentrations typically range from 112.5 to 150μg/m3, mainly from gasoline-related emissions (vehicle exhaust, gasoline processing), as well as from solvent losses and emissions from industrial activities.
Ethylbenzene
Mainly used in the production of styrene, and then the production of styrene homopolymer and styrene AS the main component of copolymer (ABS, AS, etc.). Ethylbenzene is used in a small amount in the organic synthesis industry, such as the production of acetophenone, ethyl anthraquinone, p-nitroacetophenone, methyl phenyl ketone and other intermediates. Used in medicine as an intermediate between comycin and chloramphenicol. Also used in spices. In addition, it can also be used as a solvent.
