Xylene (CAS 1330 20 7) yog ib qho tseem ceeb ntawm cov organic compound uas muaj nyob rau hauv cov chav kawm uas muaj ntxhiab hydrocarbon, yam ntxwv los ntawm ob pawg methyl (-CH₃) txuas rau lub nplhaib benzene. Nws tsis yog ib yam khoom tab sis sib xyaw ntawm peb isomers, dav siv hauv kev tsim khoom thiab lub neej txhua hnub.
Xylene Properties
Xylenenthuav tawm cov khoom siv tshuaj ruaj khov, nrog rau nws lub cev lub cev thiab cov qauv txiav txim siab nws cov ntawv thov. Cov ntaub ntawv tseem ceeb yog raws li nram no:
Lub cev muaj zog:Nyob rau hauv chav tsev kub, nws yog ib tug tsis muaj kob, pob tshab kua nrog ib tug txawv aromatic tsw. Nws yog volatile heev, flammable, insoluble nyob rau hauv dej, thiab soluble nyob rau hauv organic solvents xws li ethanol thiab diethyl ether.
Isomers:Muab faib ua peb hom raws li txoj haujlwm ntawm ob pawg methyl ntawm lub nplhaib benzene. Industrially, lawv feem ntau siv nyob rau hauv ib tug sib tov (hu ua "mixed xylene"):
- o-Xylene (o-Xylene): Ob pawg methyl nyob ib sab ntawm lub nplhaib benzene. Feem ntau siv rau hauv kev tsim cov phthalic anhydride (cov khoom siv raw rau plastics thiab coatings).
- M-Xylene (m-Xylene): Ob pawg methyl nyob rau sab nraud ntawm lub nplhaib benzene. Nws yog ib qho tseem ceeb raw khoom rau kev tsim m-Terephthalic Acid, siv nyob rau hauv manufacturing fibers thiab resins.
- Para-xylene (p-xylene): Ob pawg methyl yog nyob rau hauv ib leeg ntawm lub nplhaib benzene. Qhov no yog hom siv dav tshaj plaws, feem ntau yog los tsim cov dimethyl terephthalate (cov khoom siv tseem ceeb rau PET plastics thiab polyester fibers).
Xylene siv
- Kev Tsim Khoom Siv Tshuaj: Ib qho tseem ceeb nruab nrab hauv kev tsim cov yas, hluavtaws fibers, thiab resins. Piv txwv li, cov khoom siv niaj hnub xws li lub raj mis dej ntxhia (ua los ntawm cov khoom siv PET) thiab cov khaub ncaws polyester cia siab rau para-xylene ua cov khoom siv tseem ceeb.
- Solvent Applications: Vim nws muaj zog solubility, nws yog ib qho hnyav rau cov xim, coatings, inks, thiab adhesives. Nws kuj yog siv los ntxuav thiab dilution hauv roj hmab thiab tawv ua.
- Lwm Daim Ntawv Thov: Hauv kev lag luam kws tshuaj, nws ua haujlwm pabcuam hnyav rau cov tshuaj synthesis. Hauv cov chaw soj nstuam, nws ua haujlwm raws li cov tshuaj reagent rau cov qauv rho tawm thiab sib cais.
Tej Xylene Nqe
Cov nqi sib txawv raws cheeb tsam, purity, qib (Industrial Grade / High Purity / Anhydrous), thiab tus nqi thauj khoom. Cov lus hauv qab no muab cov nqi siv ntau rau - cov neeg yuav khoom loj.
| Thaj tsam | Tus nqi ntau (USD / MT) | Qib |
|---|---|---|
| Tuam Tshoj | $750 – $980 / MT | Qib Industrial 99% |
| Southeast Asia | $820 – $1050 / MT | 99–99.5% |
| Is Nrias teb | $890 – $1100 / MT | 99–99.5% |
| Middle East | $780 – $1000 / MT | 99% |
| South America | $950–$1200 / MT | Qib Industrial |
| Teb chaws Europe | $1100 – $1350 / MT | Siab Purity |
