Diisooctyl phthalate CAS 27554-26-3
Diisooctyl phthalate waxay leedahay sifooyinka guud ee jirka iyo kiimikaad ee xeryahooda benzoate. Sifooyinka kiimikaad ee walaxdan waxay inta badan ku urursan yihiin laba unug oo ester ah oo ku yaal giraanta benzene. Waxa ay mari kartaa falcelinta isugeynta nucleophilic ee hoos timaada ficilka reagents nucleophilic xooggan sida qaab reagent iyo organolith reagent. Unugga ester-ka ee qaab-dhismeedka walaxda ayaa sidoo kale loo beddeli karaa kooxda hydroxyl ee u dhiganta iyada oo la raacayo ficilka wakiilka yaraynta xooggan.

Phthalic acid waxa loo isticmaali karaa sidii caagadiyaha, gaaska chromatographic fixative, wakiilka adag, dareeraha iyo balaastiga. Diisooctyl waxay leedahay sifooyin jidheed iyo kiimiko oo la mid ah benzoate, waxaana inta badan loo isticmaalaa sida dareeraha organic iyo balaastiga warshadaha walxaha polymer ee wax soo saarka kiimikada. Plasticizer (plasticizer) waa wax lagu daro walxaha polymer, balaastik lagu daray walxaha polymerka, iyada oo aan la beddelin sifooyinka kiimikada aasaasiga ah, hoos u dhigida dhalaalka dhalaalka, heerkulka kala-guurka dhalada iyo taabashada laastikada, si loo hagaajiyo habsocodka, iyo hagaajinta jilicsanaanta alaabta iyo sifooyinka jilicsan ee walaxda.
Caadi ahaan waxaa lagu soo buuxiyaa 180kg/durbaan, sidoo kale waxaa la samayn karaa xirmo habaysan.
