Get the detailed answer: What is the specific heat of benzene? (August 2007). Pure Benzene (C_6H_6) has a melting point of 5.5 degrees Celsius. 2039504. Khim., 1941, 11, 471-482. Smaller amounts of benzene are used to make some types of rubbers, lubricants, dyes, detergents, drugs, explosives, and pesticides. You simply need a household iron to apply heat to loosen the adhesive and weaken the prints to get them out easily. In the body, benzene is enzymatically converted to a series of oxidation products including muconic acid, phenylmercapturic acid, phenol, catechol, hydroquinone and 1,2,4-trihydroxybenzene.
