Mixed Xylene siv rau dab tsi?
CAS 1330-20-7 Mixed xylene yog qib workhorse hnyav ntawm tsev neeg xylene. Vim tias nws yog ib qho kev sib xyaw es tsis yog ib qho purified isomer, nws yog tus nqi ntau dua - siv tau rau cov ntawv thov uas muaj qhov hnyav thiab evaporation tswj muaj teeb meem ntau dua li isomer purity. Nws yog dav siv los ua ib qho hnyav hnyav lossis ib feem ntawm cov kuab tshuaj sib xyaw hauv:
- Cov kuab tshuaj-raws li kev lag luam thiab cov xim hlau
- Kev tiv thaiv thiab tshuab txheej
- Alkyd resin-raws li formulations
- Cov kuab tshuaj-raws li cov nplaum thiab roj hmab cements
- Printing inks sib xws nrog cov kuab tshuaj tsw qab
- Muaj kev tu thiab degreasing hauv qee qhov kev siv

o-Xylene siv rau dab tsi?
CAS 95-47-6 o-Xylene feem ntau yog siv los ua cov tshuaj nruab nrab es tsis yog cov kuab tshuaj. Nws cov dej ntws loj tshaj plaws siv thoob ntiaj teb yog raws li cov khoom noj rau phthalic anhydride, uas yog siv los tsim PVC plasticizers thiab unsaturated polyester thiab alkyd resins. o-Xylene kuj tseem siv tau los ua cov kuab tshuaj hauv cov xim, kua roj vanish, inks thiab tshuaj tua kab formulations, thiab raws li ib tug nruab nrab ntawm ib co dye thiab agrochemical synthesis. GNEE BIO covo-Xylene (CAS 95-47-6) nplooj ntawvthiab peb tsab xov xwm kev paub "Ortho-xylene (o-xylene) siv rau dab tsi?" npog qhov no kom ntxaws ntxiv.
Vim li cas Isomer Composition Matters Thaum Sourcing Xylene
Vim hais tias "xylene" yog qee zaum siv xoob hauv kev ua lag luam, cov neeg yuav khoom yuav tsum paub meej tias:
- Cov khoom puas yog sib xyaw lossis ib qho isomer? Ib qho sib xyaw xylene COA yuav tsum qhia qhov kwv yees o-/m-/p-xylene piv thiab ethylbenzene cov ntsiab lus; ib qho o-xylene COA yuav tsum lees paub qhov tsawg kawg nkaus purity ntawm ortho isomer.
- Lub hom phiaj siv kawg yog dab tsi? Cov ntaub ntawv hnyav (xim, txheej, nplaum, inks) feem ntau hu rau cov xylene sib xyaw, thaum phthalic anhydride thiab cov tshuaj sib xyaw ua ke zoo sib xws yuav tsum siab dua -purity o-xylene.
- Cov ntaub ntawv dab tsi muaj? Nco ntsoov thov COA, SDS / MSDS thiab TDS kom paub meej tias isomer piv, purity thiab kev nyab xeeb kev faib ua ntej yuav khoom.
Kev muab cov qib tsis raug tuaj yeem cuam tshuam rau kev ua haujlwm hnyav, kev tswj hwm kev faib tawm thiab tus nqi, yog li nws tsim nyog lees paub tus lej CAS thiab cov lus qhia tshwj xeeb nrog koj tus neeg xa khoom ua ntej ua tiav qhov kev txiav txim.

FAQ: Mixed Xylene vs. o-Xylene
Q: o-xylene puas tuaj yeem siv los hloov cov xylene sib xyaw hauv cov xim pleev xim?
Qee zaum o-xylene tuaj yeem siv los ua cov kuab tshuaj, tab sis vim tias nws yog ib qho isomer nws coj txawv me ntsis hauv kev daws teeb meem thiab evaporation piv rau cov sib xyaw xylene sib xyaw, thiab nws feem ntau raug nqi thiab muab los ua cov tshuaj nruab nrab es tsis yog cov xim hnyav. Kev kuaj pom zoo ua ntej hloov pauv.
Q: Puas yog xylene sib xyaw muaj o-xylene?
Yog lawm. Kev lag luam sib xyaw xylene yog ib qho kev sib xyaw uas suav nrog o-xylene nrog rau m-xylene, p-xylene thiab feem ntau taug qab ethylbenzene - qhov sib piv pes tsawg nyob ntawm qhov chaw tsim khoom thiab qib.
Q: Qhov twg kuv yuav tsum xaj - sib xyaw xylene lossis o-xylene?
Yog tias koj tab tom tsim cov xim pleev xim, txheej txheej, cov nplaum lossis cov tshuaj pleev xim, cov xylene sib xyaw (CAS 1330-20-7) feem ntau yog cov khoom raug. Yog tias koj tab tom tsim phthalic anhydride lossis lwm yam tshuaj nruab nrab, o-xylene (CAS 95-47-6) feem ntau yuav tsum tau. Hu rau GNEE BIO yog tias koj tsis paub meej tias qib twg haum rau koj daim ntawv thov.
