Styrene itself is a liquid that can be handled easily and safely. In this experiment, we will use three properties to identify a liquid substance: solubility, density and boiling point.. Dehydrogenation of ethylbenzene is carried out in the presence of steam, which has a threefold role: 1) It lowers the partial pressure of ethylbenzene, shifting the equilibrium toward styrene and minimizing the loss to thermal cracking 2) It supplies the necessary heat of reaction 3) It cleans the catalyst by reacting with carbon to produce carbon dioxide and hydrogen. Ethylbenzene is used primarily in the production of styrene.
