DOP dioctyl phthalate, lub npe tag nrho dioctyl phthalate, yog ib qho khoom siv yas nrog cov tshuaj formula C24H38O4. Hauv nws cov qauv molecular, muaj ob pawg ester uas cuam tshuam nrog ib leeg los ntawm kev sib txuas ntawm phthalic acid. Nws yog xim tsis muaj xim, pob tshab kua nrog zoo solubility thiab plasticizing zog. Nws feem ntau yog siv los ua cov yas yas rau ntau yam khoom siv xws li PVC (polyvinyl chloride). Nws tuaj yeem txhim kho qhov yooj yim thiab kev ua tiav ntawm cov yas los ntawm kev tawg thiab nkag mus.
DOP dioctyl phthalate yog cov yas siv ntau tshaj plaws. Ntxiv rau cellulose acetate thiab polyvinyl acetate, nws muaj kev sib raug zoo nrog feem ntau cov khoom siv hluavtaws thiab cov roj hmab siv hauv kev lag luam. Cov khoom no muaj cov khoom zoo, cov khoom sib xyaw zoo, cov khoom siv plasticizing siab, tsis tshua muaj hluav taws xob, qhov kub thiab txias yooj yim, dej extraction tsis kam, hluav taws xob siab, zoo tshav kub thiab huab cua tsis kam. Raws li lub ntsiab plasticizer, cov khoom no yog dav siv nyob rau hauv kev ua ntawm ntau yam khoom muag ntawm polyvinyl chloride, xws li films, nplooj ntawv, dag tawv, cov ntaub ntawv cable, thiab molded khoom. Cov khoom no tsis muaj tshuaj lom thiab tuaj yeem siv rau cov khoom ntim hauv kev sib cuag nrog cov khoom noj, tab sis nws tsis haum rau cov khoom noj muaj roj vim nws yooj yim tshem tawm cov rog. Nws kuj tuaj yeem siv rau hauv cov xim nitrocellulose los ua cov xim pleev xim muaj elasticity thiab siab tensile zog. Ntawm ntau yam hluavtaws roj hmab, DOP dioctyl phthalate kuj muaj cov nyhuv softening. Tsis tas li ntawd, DOP kuj tseem siv los ua tus neeg sawv cev condensing, tus neeg saib xyuas kev sib txhuam, cov kuab tshuaj organic, roj chromatography nyob ruaj khov kua, thiab lwm yam.
