Diisooctyl phthalate CAS 27554-26-3
Diisooctyl phthalate muaj cov khoom siv lub cev thiab tshuaj lom neeg ntawm cov tshuaj benzoate. Cov khoom siv tshuaj lom neeg ntawm cov tshuaj no feem ntau yog concentrated hauv ob lub ester units ntawm lub nplhaib benzene. Nws tuaj yeem dhau los ntawm kev sib ntxiv nucleophilic nyob rau hauv qhov kev ua ntawm cov tshuaj nucleophilic muaj zog xws li hom reagent thiab organolith reagent. Lub ester unit hauv cov qauv ntawm cov tshuaj kuj tseem tuaj yeem hloov pauv mus rau hauv pawg hydroxyl sib xws nyob rau hauv qhov kev ua ntawm tus neeg sawv cev txo qis muaj zog.

Phthalic acid siv tau ua plasticizer, roj chromatographic fixative, toughening agent, solvent thiab plasticizer. Diisooctyl muaj cov khoom zoo sib xws rau benzoate, thiab nws feem ntau yog siv ua cov organic solvent thiab plasticizer hauv kev lag luam polymer hauv kev tsim tshuaj lom neeg. Plasticizer (plasticizer) yog cov khoom siv polymer ntxiv, plasticizer ntxiv rau cov khoom polymer, tsis hloov nws cov khoom siv tshuaj lom neeg yooj yim, txo nws cov viscosity yaj, qhov kub hloov iav thiab kov elastic, yog li txhim kho nws cov txheej txheem ua haujlwm, thiab txhim kho cov khoom mos thiab tensile zog ntawm cov tshuaj.
Feem ntau ntim rau hauv 180kg / nruas, thiab kuj tuaj yeem ua pob khoom raws li koj xav tau.
