Synthetic
Not Clean
OriginSynthesized from phthalic anhydride and a mixture of benzyl alcohol and butanol through esterification reactions. Produced via acid-catalyzed condensation of these starting materials to create the phthalate ester compound.
Butyl benzyl phthalate appears as a clear colorless liquid with a mild odor. Primary hazard is to the environment. Immediate steps should be taken to limit spread to the environment. Easily penetrates the soil to contaminate groundwater and nearby waterways.
Solubility less than 0.1 mg/mL at 72.5 °F (NTP, 1992)
