Ethyl methyl carbonateyog ib qho organic compound nrog cov tshuaj formula C5H8O3, tseem hu ua EMC. Nws yog xim tsis muaj xim, pob tshab, thiab cov kua dej tsis haum nrog cov tshuaj toxicity tsawg thiab volatility. EMC feem ntau yog siv los ua cov khoom siv raw hauv cov teb xws li cov kuab tshuaj, txheej, yas, resins, txuj lom, thiab tshuaj. Nws tuaj yeem siv los npaj lwm cov organic sib txuas, xws li polycarbonate. Hauv kev tsim khoom, kev tsim khoom ntawm EMC feem ntau siv cov tshuaj tiv thaiv ester pauv lossis carbonation esterification cov tshuaj tiv thaiv.
Khoom npe: Ethyl methyl carbonate
CAS:623-53-0
Cov mis mos molecular: C4H8O3
PIB: 433-480-9
Daim ntawv thov nram qab no ntawm EMC feem ntau yog lithium-ion roj teeb electrolyte, uas yog ib qho ntawm plaub cov ntaub ntawv tseem ceeb ntawm lithium-ion roj teeb thiab tseem hu ua "ntshav" ntawm cov roj teeb.
EMC muab faib ua ob pawg raws li purity: qib methyl ethyl carbonate (99.9%) thiab roj teeb qib EMC (99.99% lossis siab dua). Muaj qib EMC feem ntau yog siv rau hauv kev lag luam organic synthesis thiab cov kuab tshuaj; Lub roj teeb qib EMC cov txheej txheem yuav tsum muaj ntau dua thiab feem ntau yog siv los ua cov kuab tshuaj rau lithium-ion roj teeb electrolytes. Vim nws qhov me me steric hindrance thiab asymmetry nyob rau hauv cov qauv, nws muaj peev xwm pab nyob rau hauv nce lub solubility ntawm lithium ions, kev txhim kho lub capacitance ceev thiab nqi ntawm lub roj teeb, thiab tau dhau los ua ib qho ntawm tsib lub ntsiab hnyav rau lithium-ion roj teeb electrolytes.
Daim ntawv thov nram qab no ntawm EMC feem ntau yog lithium-ion roj teeb electrolyte, uas yog ib qho ntawm plaub cov ntaub ntawv tseem ceeb ntawm lithium-ion roj teeb thiab tseem hu ua "ntshav" ntawm cov roj teeb. Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm kev lag luam tsheb tshiab, Tuam Tshoj lub lithium-ion roj teeb electrolyte kev lag luam tau nkag mus rau lub sijhawm ntawm kev loj hlob sai. Tus nqi hauv cheeb tsam ntawm electrolytes tau nce ntxiv, thiab kev hloov pauv hloov pauv tau ua tiav, ua rau kev loj hlob sai ntawm kev thov rau EMC hauv Tuam Tshoj txoj kev lag luam. Raws li "2023-2027 Tuam Tshoj EMC Kev Lag Luam Kev Lag Luam Kev Tshawb Fawb Kev Tshawb Fawb Txog Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Tshawb Fawb Txog Kev Tshawb Fawb" tso tawm los ntawm Xinsijie Kev Tshawb Fawb Kev Lag Luam, hauv 2021, qhov kev thov rau EMC hauv Suav teb yog 139500 tons, ib xyoos ib zaug nce ntawm 94.7% .
Kev ua lag luam rauEMCtau qhia txog kev loj hlob tsis tu ncua hauv ob peb xyoos dhau los. Qhov no feem ntau yog vim kev siv EMC thoob plaws hauv ntau daim ntawv thov kev lag luam, xws li cov kuab tshuaj, txheej, yas, resins, txuj lom, thiab tshuaj. Tsis tas li ntawd, nrog rau txoj kev loj hlob ntawm kev lag luam thoob ntiaj teb thiab kev txhim kho ntawm tib neeg txoj kev ua neej nyob, qhov kev thov rau EMC kuj maj mam nce.
Tam sim no, cov neeg siv khoom tseem ceeb ntawm EMC kev lag luam suav nrog thaj av Asia Pacific, Europe, thiab North America. Cov cheeb tsam Asia Pacific yog thaj chaw neeg siv khoom tseem ceeb ntawm kev lag luam methyl ethyl carbonate, nrog Tuam Tshoj, Nyiv, thiab Kaus Lim Qab Teb yog cov neeg tsim khoom loj thiab cov neeg siv khoom ntawm EMC. Kev ua lag luam rau EMC hauv Tebchaws Europe thiab North America tseem maj mam loj hlob, nrog rau lub teb chaws Yelemees, United Kingdom, Tebchaws Meskas, thiab Canada yog cov neeg siv khoom tseem ceeb ntawm EMC.
Nyob rau yav tom ntej, kev loj hlob ntawm EMC kev lag luam yuav cuam tshuam los ntawm kev lag luam thoob ntiaj teb thiab kev tsim kho kev lag luam. Nrog rau kev nce ntawm cov lag luam tawm tshiab thiab kev nce qib kev siv tshuab txuas ntxiv, qhov kev thov rau EMC hauv kev ua lag luam yuav loj hlob ntxiv. Tsis tas li ntawd, kev tiv thaiv ib puag ncig thiab kev tsim kho kom ruaj khov kuj tseem yuav dhau los ua qhov tseem ceeb hauv kev lag luam EMC, txhawb kev tsim khoom thiab siv EMC kom muaj kev nyab xeeb thiab ruaj khov.
