Physical Properties / Chemical Properties

Since we are focusing on a group of compounds we can't give an exact physical or chemical description. Instead, we chose to focus on dimethyl. It is the simplest form of phthalate and it will serve as the phthalate property representative. Dimethyl is a clear oily liquid with a density of 1.19 g/cm3. Its melting point is 2°C and its boiling point is between 283 and 284°C. It is slightly soluble in water. Dimethyl phthalate also has chemical properties. It reacts with acids. Dimethyl is also combustible (flammable).
