How benzene is produced
WebBenzene (C6H6) reacts with oxygen (O2) to make carbon dioxide (CO2) and water (H2O). Complete combustion does NOT give carbon monoxide or soot.Check me out: ... WebEthylbenzene is commercially produced from benzene and ethylene in industrial plants, and a minor amount is isolated by purifying petroleum by-product streams. It is also present naturally in crude oil, some natural gas streams, and coal tar. Over 98% of synthetic ethylbenzene is used as a raw material in the manufacture of styrene monomer.
