Description
Diethyl phthalate (DEP) is a member of the group of esters of phthalic acid known as phthalates, used ubiquitously as solvents and plasticisers worldwide. DEP can increases the flexibility of plastics. It is also contained in deodorant formulations, perfumes, emollients and insect repellents. It can cross react with dimethyl phtalate.

Uses
Diethyl phthalate is a Plasticizer for cellulose ester plastic films and sheets; in molded plastics; manufacturing varnishes; cosmetics. Diethyl phthalate has been used as a substitute for camphor in the manufacture of celluloid, as a solvent for cellulose acetate in the manufacture of varnishes and dopes, as a ftxative for perfumes, and for denaturing ethanol. Diethyl phthalate is an intermediate of the rodenticides dimouse, murine, and chlorpyrone, and is also an important solvent. Diethyl phthalate is used as a plasticizer for plastics. Diethyl phthalate is used as an analytical reagent, a gas chromatography stationary solution, a solvent for cellulose and esters, a plasticizer and a lubricant. Diethyl phthalate is used as plasticizer, solvent, lubricant, fixative, foaming agent for colored or rare metal mine flotation, gas chromatography fixative, alcohol denaturant, spray insecticide. This product is mixed with cellulose acetate, cellulose acetate butyrate, polyvinyl acetate, nitrocellulose, ethyl cellulose, polymethyl methacrylate, polystyrene, polyvinyl butyral, vinyl chloride-vinyl acetate Most resins such as copolymers have good compatibility. It is mainly used as a plasticizer for cellulose resin, but the product has high volatility, which limits its wide application.
