Products Description of Dibutyl Phthalate CAS#84-74-2

Dibutyl phthalate (DBP) industrial grade has a purity of ≥99% and is a flammable, colorless, transparent oily liquid with a characteristic aromatic odor. It has a melting point of -35 °C and a boiling point of 338 °C, with a vapor pressure of 0.014 Pa at 25 °C and a relative density of 1.045 at 20 °C. DBP is slightly soluble in water (0.03 g/L at 25 °C) but readily dissolves in most organic solvents. The compound is chemically stable under normal conditions but should be kept away from strong oxidizers, acids, and alkalis.
