WebIt is an aromatic organic compound with the molecular formula C6H6. Benzene is available abundantly in nature. There is no need to make it synthetically as it is mostly a natural component in gas emissions in volcanic fires or forest fires and it is also found in gasoline, crude oil and cigarette smoke. WebAlmost all styrene is now produced by dehydrogenation of ethylbenzene, a compound obtained by reacting ethylene and benzene —both of which in turn are derived from petroleum. More than 15 million metric tons of the liquid are made each year.
