Tus qauv ntawm para xylene (CAS 106-42-3) yog dab tsi?

Para xylene qauv (CAS 106-42-3)

Para xyleneyog nyob rau hauv txoj haujlwm ntawm ob pawg methyl, lawv cov qauv hloov pauv, uas nws txawv ntawm lwm cov isomers, o-xylene thiab m-xylene. Txhua tus muaj tib yam tshuaj formula C6H4(CH3)2. Tag nrho cov xylene isomers yog cov xim tsis muaj xim thiab muaj cov nplaim taws heev.

p-Xylene (PX) yog dab tsi?

P-xylene (para xylene), feem ntau hu ua PX, yog cov organic compound, cov tshuaj formula yog C8H10, yog ib qho ntawm cov tseem ceeb aromatic compounds, nyob rau hauv chav tsev kub yog ib tug tsis muaj kob pob tshab kua nrog ib tug aromatic tsw, insoluble nyob rau hauv dej, miscible nyob rau hauv ethanol, ethyl ether, chloroform thiab lwm yam organic solvents.

PX yog Feem ntau yog siv los ua cov khoom siv raw rau kev tsim cov polyester fibers thiab resins, coatings, dyes, thiab tshuaj tua kab, tab sis kuj siv los ua tus qauv rau kev tshuaj xyuas chromatographic. Nws yog tsuas yog siv los ua raw khoom rau zus tau tej cov polyester fiber thiab resin, xim, dyestuff thiab tshuaj tua kab, thiab kuj siv raws li tus qauv rau chromatographic tsom xam thiab hnyav.

Qhov txawv ntawm xylene thiab para-xylene yog dab tsi?

Xylene yog dav siv los ua cov organic hnyav, tshwj xeeb tshaj yog nyob rau hauv kev lag luam siv xws li txheej, xim, nplaum, thiab tshuaj ntxuav. Nws kuj tseem ua haujlwm tseem ceeb hauv kev sib txuas ntawm ntau yam khoom siv tshuaj, suav nrog dyes, plastics, roj hmab, thiab tshuaj. Para-Xylene, txawm li cas los xij, muaj qhov xav tau siab tshaj plaws thiab feem ntau yog siv los tsim cov khoom siv tshuaj xws li polyester.

Dab tsi yog siv rau Para-xylene (PX)?

Para-xylene (PX) yog ib qho tseem ceeb nruab nrab uas txuas cov kev lag luam petrochemical nrog cov khoom siv textile thiab ntim khoom. Ntau tshaj 90% ntawm lub ntiaj teb no PX tso zis yog siv los tsim PTA, thiab nws lub ntsiab daim ntawv thov scenarios yog raws li nram no:

Thawj Daim Ntawv Thov: Kev tsim khoom ntawm PTA
PX yog oxidized nrog oxygen hauv lub reactor los tsim Purified Terephthalic Acid (PTA). PTA yog tom qab ntawd polymerized nrog ethylene glycol (EG) los ua polyethylene terephthalate (PET)-ib lub ntiaj teb siab tshaj - ntim hluavtaws resins. PET yog siv dav hauv:

Kev Lag Luam Textile
Hloov mus rau hauv polyester fibers (xws li, polyester), accounting rau ntau tshaj 70% ntawm ntiaj teb no hluavtaws fiber ntau lawm. Cov fibers no yog siv rau hauv khaub ncaws, tsev textiles, thiab industrial fabrics xws li canvas thiab lim ntaub.

Ntim Kev Lag Luam
Ua tiav rau hauv PET lub raj mis yas (lub raj mis dej haus, lub raj mis roj noj) thiab cov khoom ntim khoom noj. PET tau txais kev pom zoo rau nws qhov siab pob tshab, cuam tshuam tsis kam, thiab rov ua dua tshiab, ua rau nws muaj kev nyab xeeb dua thiab muaj txiaj ntsig zoo dua rau cov iav thiab PVC ntim.

Engineering Plastics
Hloov kho PET resin yog siv los tsim cov khoom siv hluav taws xob siab -lub zog engineering yas rau cov khoom siv tsheb (bumpers, dashboards) thiab cov khoom siv hluav taws xob.
