General description

Diethyl phthalate (DEP) is a phthalic anhydride ester (PAE) that is commonly used as a solvent in cosmetics and also as a plasticizer.

Application

Diethyl phthalate can be used as a solvent for the antimony reduction of aluminum chloride-phosphorus trichloride-alkyl chloride complexes to form the corresponding alkylphosphonous dichlorides. It can undergo condensation with o-phenylenediamine in the presence of sodium hydride to form dibenzo (b,f)(1,4)diazocine-6,11(5H, 12H)-dione.

Packaging
