Kufotokozera
Dibutyl phthalate, yomwe imadziwikanso kuti dibutyl phthalate kapena dibutyl phthalate, English: Dibutylphthalate, ndi madzi onyezimira osawoneka bwino okhala ndi mphamvu yokoka ya 1.045 (21°C) ndi malo otentha a 340°C, osasungunuka m'madzi, osasungunuka m'madzi komanso kusakhazikika Makhalidwe ake ndi otsika kwambiri, koma amasungunuka mosavuta mu zosungunulira za organic monga ethanol, etha, acetone ndi benzene, komanso amasakanikirana ndi ma hydrocarbon ambiri.Dibutyl phthalate (DBP), dioctyl phthalate (DOP) ndi diisobutyl phthalate (DIBP) ndi mapulasitiki atatu omwe amagwiritsidwa ntchito kwambiri, omwe ndi mapulasitiki, mphira wopangidwa ndi zikopa zopangira, ndi zina zotero.Imapezedwa ndi matenthedwe esterification a phthalic anhydride ndi n-butanol.
Chemical Properties
Mafuta amadzimadzi osawoneka bwino komanso onunkhira pang'ono.Zosungunuka m'ma organic solvents ndi ma hydrocarbon.
Kugwiritsa ntchito
- Amagwiritsidwa ntchito ngati plasticizer ya nitrocellulose, cellulose acetate, polyvinyl chloride, etc. Izi ndi plasticizer.Lili ndi mphamvu zosungunula ku ma resins osiyanasiyana.
-Yogwiritsidwa ntchito pokonza PVC, imatha kupereka kufewa kwazinthu.Chifukwa cha mtengo wake wotsika mtengo komanso wabwino, amagwiritsidwa ntchito kwambiri, pafupifupi ofanana ndi DOP.Komabe, kusasunthika ndi kutulutsa madzi kumakhala kwakukulu, kotero kuti kukhazikika kwa mankhwalawa ndi kosauka, ndipo kugwiritsidwa ntchito kwake kuyenera kuchepetsedwa pang'onopang'ono.Izi ndi plasticizer wabwino kwambiri wa nitrocellulose ndipo ali ndi mphamvu yamphamvu ya gelling.
-Yogwiritsidwa ntchito popaka nitrocellulose, imakhala ndi zotsatira zabwino kwambiri zofewetsa.Kukhazikika kwabwino, kukana kusinthasintha, kumamatira komanso kukana madzi.Komanso, mankhwala angagwiritsidwe ntchito monga plasticizer kwa polyvinyl acetate, alkyd utomoni, ethyl mapadi ndi neoprene, ndipo angagwiritsidwenso ntchito popanga utoto, zomatira, chikopa yokumba, inki kusindikiza, galasi chitetezo, celluloid, utoto, mankhwala ophera tizilombo. , zosungunulira zonunkhira, mafuta opangira nsalu, etc.
- Monga pulasitiki ya cellulose ester, mchere ndi mphira wachilengedwe, polystyrene;kupanga polyvinyl chloride ndi copolymers kuzizira zosagwira organic synthesis, ion selective electrode additives, solvents, insecticides, plasticizers, Gas chromatography stationary fluid (kutentha kwambiri 100 ℃, zosungunulira ndi acetone, benzene, dichloromethane, ethanoltion), kusankha retennol kulekana kwa mankhwala onunkhira, mankhwala osatuta, mankhwala a terpene ndi mankhwala osiyanasiyana okhala ndi okosijeni (mowa, aldehydes, ketoni, esters, etc.).
