CAS 106-42-3 Para-xylene (PX)yog ib qho xim tsis muaj xim, flammable heev aromatic hydrocarbon. Raws li cov khoom lag luam tseem ceeb petrochemical refined los ntawm cov roj crude thiab hloov cov roj av, nws tuav cov nqi lag luam tshwj xeeb. Ib qho ntawm peb lub xylene isomers, nws qhov tshwj xeeb symmetry thiab cov qauv tshuaj muaj peev xwm ua kom loj - nplai polymer synthesis.
p-Xylene ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv niaj hnub xws li polyester fibers, PET fwj, thiab ntim zaj duab xis.
Cov ntawv thov kev lag luam ntawm Para-xylene
Polyester
Paraxylene (PX) yog lub hauv paus raw khoom rau kev tsim purified terephthalic acid (PTA), uas nyob rau hauv lem ua raws li cov tub ntxhais feedstock rau polyester ntau lawm. Ua tsaug rau lawv cov kav ntev, tsis kam tiv thaiv, thiab cov nqi ua haujlwm, polyester fibers ua los ntawm paraxylene yog ubiquitous hauv khaub ncaws, tsev textiles, thiab kev lag luam.
Textiles
Polyester fiber ntau ua los ntawm para-xylene ua haujlwm tseem ceeb rau kev lag luam textile. Cov fibers no yog spun rau hauv xov paj thiab woven rau hauv fabrics rau apparel, upholstery, thiab technical textiles.
Cov khoom ntim
Polyethylene terephthalate (PET), uas yog muab los ntawm paraxylene -raws li tshuaj intermediates, yog ib qho ntawm cov khoom ntim siv dav tshaj plaws niaj hnub no, muaj nyob rau hauv ob qho tib si nruj thiab hloov tau. Nws yog cov khoom siv rau kev ntim cov dej haus, khoom noj, tshuaj, thiab cov khoom siv tu tsev vim nws lub zog siab, nruj, pob tshab, thiab zoo heev tiv taus ya raws, oxygen, thiab carbon dioxide.
Yas Zaj duab xis
P-Xylene (PX) ua lub luag haujlwm tseem ceeb hauv kev tsim cov yeeb yaj kiab yas, tshwj xeeb tshaj yog polyethylene terephthalate (PET) zaj duab xis. Cov yeeb yaj kiab no yog siv rau hauv cov khoom ntim khoom noj, cov ntaub nplaum sib nqus, hluav taws xob rwb thaiv tsev, thiab kev tsim cov khoom siv capacitor.
Cov kuab tshuaj
Thaum para-xylene nws tus kheej tsis yog cov khoom lag luam loj, nws cov txheeb ze tshuaj (lwm cov xylenes) feem ntau yog siv los ua cov kuab tshuaj hauv cov xim, cov nplaum, cov kua nplaum, thiab cov tshuaj ntxuav. P-Xylene (PX) kuj tuaj yeem muab sib xyaw rau hauv cov kuab tshuaj sib tov los pab yaj cov resins thiab dyes.
Raws li kev ntseeg siab p-Xylene cov chaw tsim khoom thiab cov chaw muag khoom, peb muab CAS 106-42-3 nrog kev tswj xyuas nruj, ruaj khov ntim khoom loj, thiab cov ntaub ntawv xa tawm thoob ntiaj teb rau cov neeg yuav khoom.
