Kev piav qhia
Dibutyl phthalate, tseem hu ua dibutyl phthalate los yog dibutyl phthalate, Lus Askiv: Dibutylphthalate, yog cov xim tsis muaj pob tshab oily kua nrog ib qho tshwj xeeb gravity ntawm 1.045 (21 ° C) thiab qhov kub ntawm 340 ° C, insoluble hauv dej, dej-soluble thiab volatile Cov khoom yog yooj yim heev soluble, tab sis cov khoom yog soluble tsawg heev. ether, acetone thiab benzene, thiab kuj yog miscible nrog feem ntau hydrocarbons. Dibutyl phthalate (DBP), dioctyl phthalate (DOP) thiab diisobutyl phthalate (DIBP) yog peb hom plasticizers, uas yog cov yas, hluavtaws roj hmab thiab tawv tawv, thiab lwm yam. feem ntau siv plasticizers. Nws yog tau los ntawm thermal esterification ntawm phthalic anhydride thiab n-butanol.
Chemical Properties
Tsis muaj xim pob tshab oily kua nrog me ntsis aromatic tsw. Soluble nyob rau hauv cov organic solvents thiab hydrocarbons.
Daim ntawv thov
-Siv raws li ib tug plasticizer rau nitrocellulose, cellulose acetate, polyvinyl chloride, thiab lwm yam. Cov khoom no yog ib tug plasticizer. Nws muaj zog dissolving zog rau ntau yam resins.
-Siv rau PVC ua, nws muaj peev xwm impart zoo softness rau cov khoom. Vim tias nws pheej yig thiab kev ua haujlwm zoo, nws tau siv dav heev, yuav luag sib npaug rau DOP. Txawm li cas los xij, qhov volatility thiab dej extraction yog qhov loj, yog li lub durability ntawm cov khoom tsis zoo, thiab nws cov kev siv yuav tsum maj mam txwv. Cov khoom no yog ib qho zoo heev plasticizer ntawm nitrocellulose thiab muaj zog gelling muaj peev xwm.
-Siv rau nitrocellulose txheej, muaj cov nyhuv softening zoo heev. Zoo heev stability, flex kuj, adhesion thiab dej tsis kam. Tsis tas li ntawd, cov khoom siv tuaj yeem siv los ua cov yas yas rau polyvinyl acetate, alkyd resin, ethyl cellulose thiab neoprene, thiab tseem tuaj yeem siv rau hauv kev tsim cov xim, nplaum, tawv tawv, luam ntawv inks, iav kev nyab xeeb, celluloid, dyes, tshuaj tua kab, tshuaj tsw qab, cov ntaub nplaum, thiab lwm yam.
- Raws li ib tug plasticizer rau cellulose ester, ntsev thiab tej yam ntuj tso roj hmab, polystyrene; ua polyvinyl chloride thiab nws cov copolymers txias-resistant rau cov organic synthesis, ion xaiv electrode additives, cov kuab tshuaj, tshuaj tua kab, plasticizers, Gas chromatography nyob twj ywm kua (qhov siab tshaj plaws siv kub 100 ℃, hnyav yog acetone, benzene, dichloromethane, ethanol), xaiv qhov sib xyaw ua ke ntawm cov tshuaj tsw qab, cov tshuaj tsw qab thiab cov tshuaj tsw qab. cov tebchaw thiab ntau yam sib txuas uas muaj cov pa oxygen (aldehydes, ketones, esters, thiab lwm yam).
