Diisooctyl phthalate CAS 27554-26-3
Diisooctyl phthalate wuxuu leeyahay sifooyinka guud ee jireed iyo kiimikada ee isku-dhafka benzoate. Sifooyinka kiimikada ee walaxdan waxaa inta badan ku urursan laba cutub oo ester ah oo ku yaal giraanta benzene. Waxay mari kartaa falcelin ku darid nucleophilic ah iyadoo la adeegsanayo falgalka falgalayaasha nucleophilic ee xooggan sida reagent-ka qaabaynta iyo reagent-ka organolith. Unugga ester-ka ee qaab-dhismeedka walaxda ayaa sidoo kale loo beddeli karaa kooxda hydroxyl ee u dhiganta iyadoo la adeegsanayo wakiil yareeya oo xooggan.

Phthalic acid waxaa loo isticmaali karaa sida balaastigeeye, hagaajin gaas chromatographic ah, wakiil adkayn, dareere iyo balaastigeeye. Diisooctyl wuxuu leeyahay sifooyin jireed iyo kiimiko oo la mid ah benzoate, waxaana inta badan loo isticmaalaa sidii dareere dabiici ah iyo balaastigeeye warshadeed oo polymer ah wax soo saarka kiimikada. Balaastigeeye (plasticizer) waa wax lagu daro walxaha polymer, balaastigeeye lagu daro walxaha polymer-ka, iyada oo aan la beddelin sifooyinkeeda kiimikada aasaasiga ah, yaraynta dhalaalka dheddiggiisa, heerkulka kala-guurka galaaska iyo taabashada laastikada, si loo hagaajiyo farsamayntiisa, loona hagaajiyo jilicsanaanta iyo sifooyinka jiidista ee sheyga.
Badanaa waxaa lagu buuxiyaa 180kg/durbaan, waxaana sidoo kale lagu samayn karaa xirmo gaar ah.
