What is the chemical reaction of petrol and thermocol?
It may look like polystyrene "melts" when petrol (gasoline) is poured on it. However, the petrol is actually dissolving the polystyrene. In chemistry, there is a common saying that "like dissolves like". Polystyrene is an alkene and petrol has several alkenes in it {benzene (up to 5% by volume), toluene (up to 35% by volume), naphthalene (up to 1% by volume), and trimethylbenzene (up to 7% by volume)} which aid in the dissolving of the polystyrene. Now the characteristics of both the ingredientsare lost and a new product is formed. This product shows the character of neither a solid nor a liquid. It is a translucent material which is brownish or yellowish white in color and with viscosity more than that of a liquid and less than that of a solid. While studying the properties of the material formed, it is found that it looks like glue and can be used as a strong adhesive.
