Instead, retain in a safe place in the laboratory (well away from any source of ignition). (The specific heat of benzene is 1.740 J/g C). [49] In 1870, the German chemist Viktor Meyer first applied Grbe's nomenclature to benzene.[50]. Ethyl alcohol likely exhibits more hydrogen bonding than water. Good, W.D. Benzene is more resistant to temperature change than sulfuric acid. In 1988 it was reported that two-thirds of all chemicals on the American Chemical Society's lists contained at least one benzene ring. Manufacture of some of these benzene-containing formulations ceased in about 1950, although Liquid Wrench continued to contain significant amounts of benzene until the late 1970s. After exposure to 63 to 405mg/m3 of benzene for 1 to 5 hours, 51 to 87% was excreted in the urine as phenol over a period of 23 to 50 hours.

Archibald Scott Couper in 1858 and Johann Josef Loschmidt in 1861[36] suggested possible structures that contained multiple double bonds or multiple rings, but too little evidence was then available to help chemists decide on any particular structure. Heats of combustion of benzene, toluene, ethyl-benzene, o-xylene, m-xylene, p-xylene, n-propylbenzene, and styrene, The measurement of benzene in humans can be accomplished via urine, blood, and breath tests; however, all of these have their limitations because benzene is rapidly metabolized in the human body. Molecular Formula / Molecular Weight. The American Petroleum Institute (API) stated in 1948 that "it is generally considered that the only absolutely safe concentration for benzene is zero". All rights reserved. Measurement of air and water levels of benzene is accomplished through collection via activated charcoal tubes, which are then analyzed with a gas chromatograph.

In 2005, the water supply to the city of Harbin in China with a population of almost nine million people, was cut off because of a major benzene exposure. For commercial use, until World War II, much of benzene was obtained as a by-product of coke production (or "coke-oven light oil") for the steel industry. Am. The specific heat capacity is the heat or energy required to change one unit mass of a substance of a constant volume by 1 C. Benzene is an organic chemical compound with the molecular formula C6H6. [88] The purpose of establishing an IDLH value is (1) to ensure that the worker can escape from a given contaminated environment in the event of failure of the respiratory protection equipment and (2) is considered a maximum level above which only a highly reliable breathing apparatus providing maximum worker protection is permitted. If the sample is heated at constant pressure (P = 1 atm), calculate the amount of energy in kJ needed to raise the temperature of the sample to 102.70 C.
