Kufotokozera:
Diethyl phthalate (DEP) ndi membala wa gulu la ma esters a phthalic acid omwe amadziwika kuti phthalates, omwe amagwiritsidwa ntchito kwambiri ngati zosungunulira ndi zopaka pulasitiki padziko lonse lapansi. DEP imatha kuwonjezera kusinthasintha kwa mapulasitiki. Imapezekanso mu deodorant formulations, perfume, emollients ndi mankhwala othamangitsa tizilombo. Imatha kusakanikirana ndi dimethyl phtalate.

Kagwiritsidwe Ntchito
Diethyl phthalate ndi pulasitiki yopangira mafilimu ndi mapepala apulasitiki a cellulose ester; mu mapulasitiki opangidwa; ma varnish opanga; zodzoladzola.
Diethyl phthalate ndi gawo la pakati pa rodenticides monga dimouse, murine, ndi chlorpyrone, komanso ndi solvent yofunika kwambiri. Diethyl phthalate imagwiritsidwa ntchito ngati pulasitiki ya pulasitiki. Diethyl phthalate imagwiritsidwa ntchito ngati analytical reagent, gas chromatography stationary solution, solvent ya cellulose ndi esters, plasticizer ndi lubricant. Diethyl phthalate imagwiritsidwa ntchito ngati plasticizer, solvent, lubricant, fixative, thovu agent pa flotation yachitsulo chamitundu yosiyanasiyana kapena yosowa, gas chromatography fixative, alcohol denaturant, spray insecticide. Chogulitsachi chimasakanizidwa ndi cellulose acetate, cellulose acetate butyrate, polyvinyl acetate, nitrocellulose, ethyl cellulose, polymethyl methacrylate, polystyrene, polyvinyl butyral, vinyl chloride-vinyl acetate. Ma resins ambiri monga copolymers ali ndi mgwirizano wabwino. Amagwiritsidwa ntchito makamaka ngati plasticizer ya cellulose resin, koma mankhwalawa ali ndi volatility yayikulu, zomwe zimalepheretsa kugwiritsidwa ntchito kwake kwambiri.
Diethyl phthalate yagwiritsidwa ntchito m'malo mwa camphor popanga ma celluloid, ngati chosungunulira cha cellulose acetate popanga ma varnish ndi ma dopes, ngati chothandizira pa zonunkhira, komanso pochepetsa kukoma kwa ethanol.
