Sharaxaad:
Diethyl phthalate (DEP) waa xubin ka mid ah kooxda esters-ka ee phthalic acid oo loo yaqaan phthalates, oo si joogto ah loogu isticmaalo adduunka oo dhan sida dareereyaal iyo balaastig-sameeyayaal. DEP waxay kordhin kartaa dabacsanaanta balaastikada. Waxa kale oo ku jira qaacidooyinka carfiyaha, cadarka, emollients-ka iyo kuwa ka hortaga cayayaanka. Waxay la falgeli kartaa dimethyl phthalate.

Isticmaalka
Diethyl phthalate waa Plasticizer-ka loogu talagalay filimada iyo xaashiyaha balaastikada ah ee cellulose ester; balaastikada la qaabeeyey; soo saarista varnishes; qurxinta.
Diethyl phthalate waa dhexdhexaad ka mid ah jiirarka dimouse, murine, iyo chlorpyrone, waana dareere muhiim ah. Diethyl phthalate waxaa loo isticmaalaa sidii plasticizer oo loogu talagalay balaastikada. Diethyl phthalate waxaa loo isticmaalaa sida falanqayn falanqayn ah, xal gaas chromatography ah oo taagan, dareere cellulose iyo esters ah, plasticizer iyo saliideeye. Diethyl phthalate waxaa loo isticmaalaa sida plasticizer, dareere, saliideeye, xal hagaajin, xumbo u leh flotation macdanta birta midabka leh ama naadirka ah, hagaajinta gaaska chromatography, denaturant alcohol, buufin cayayaanka. Badeecadan waxaa lagu qasaa cellulose acetate, cellulose acetate butyrate, polyvinyl acetate, nitrocellulose, ethyl cellulose, polymethyl methacrylate, polystyrene, polyvinyl butyral, vinyl chloride-vinyl acetate. Inta badan resins sida copolymers waxay leeyihiin iswaafajin wanaagsan. Inta badan waxaa loo isticmaalaa sida plasticizer oo loogu talagalay resin cellulose, laakiin badeecadu waxay leedahay isbeddel sare, taas oo xaddidaysa codsigeeda ballaaran.
Diethyl phthalate waxaa loo isticmaalay beddelka kamfurka soo saarista celluloid, sidii dareere loogu talagalay cellulose acetate ee soo saarista varnishes iyo dopes, sida ftxative ee cadarka, iyo denaturing ethanol.
