I-Ethyl methyl carbonatei-organic compound kunye ne-chemical formula C5H8O3, eyaziwa ngokuba yi-EMC. Lulwelo olungenambala, olucacileyo, kunye noluguquguqukayo olunobuthi obuphantsi kunye nokuguquguquka. I-EMC idla ngokusetyenziswa njengento ekrwada kumasimi anje ngezinyibilikisi, iingubo, iiplastiki, iintlaka, iziqholo, kunye namayeza. Ingasetyenziselwa ukulungisa ezinye iikhompawundi eziphilayo, ezifana ne-polycarbonate. Kwimveliso yemizi-mveliso, imveliso ye-EMC ihlala ithatha i-ester exchange reaction okanye i-carbonation esterification reaction.

Igama lemveliso: Ethyl methyl carbonate

CAS:623-53-0

Ifomula yemolekyuli:C4H8O3

I-EINECS: 433-480-9

Intsimi yesicelo esisezantsi se-EMC ikakhulu yi-lithium-ion ibhetri ye-electrolyte, enye yezinto ezine eziphambili zeebhetri ze-lithium-ion kwaye zibizwa ngokucacileyo ngokuthi "igazi" leebhetri.

I-EMC yohlulwe yangamacandelo amabini asekelwe kubunyulu: ibakala leshishini le-methyl ethyl carbonate (99.9%) kunye nebakala lebhetri i-EMC (99.99% okanye ngaphezulu). I-EMC ye-Industrial grade isetyenziswa ikakhulu kwi-industrial organic synthesis kunye nezinyibilikisi; Inkqubo ye-EMC yomgangatho webhetri ifuna iimfuno eziphezulu kwaye isetyenziswa ikakhulu njenge-solvent ye-lithium-ion battery electrolytes. Ngenxa yesithintelo esincinci se-steric kunye ne-asymmetry kwisakhiwo, inokunceda ekwandiseni ukunyibilika kwe-lithium ion, ukuphucula ukuxinwa kwe-capacitance kunye nokuhlawuliswa kwebhetri, kwaye ibe yenye yezona zintlanu zokunyibilikisa i-lithium-ion ibhetri ye-electrolyte.

Intsimi yesicelo esisezantsi se-EMC ikakhulu yi-lithium-ion ibhetri ye-electrolyte, enye yezinto ezine eziphambili zeebhetri ze-lithium-ion kwaye zibizwa ngokucacileyo ngokuthi "igazi" leebhetri. Kwiminyaka yakutshanje, kunye nophuhliso olukhawulezayo lweshishini elitsha lezithuthi zamandla, ishishini laseTshayina i-lithium-ion ibhetri ye-electrolyte ingene kwixesha lophuhliso olukhawulezayo. Izinga le-electrolyte yasekhaya linyuke kakhulu, kwaye ukufakwa endaweni yokungenisa elizweni kuphunyeziwe, kuqhuba ukukhula okukhawulezayo kwemfuno ye-EMC kwimarike yaseTshayina. Ngokutsho kwe "2023-2027 China EMC Industry Market deep Research and Development Prospects Reports Reports" ekhutshwe yi-Xinsijie Industry Research Centre, ngo-2021, imfuno ye-EMC e-China yayiyi-139500 yeetoni, ukunyuka konyaka-ngonyaka kwe-94.7% .

Imarike yeI-EMCibonise ukukhula okuzinzileyo kule minyaka imbalwa idlulileyo. Oku kungenxa yokusetyenziswa ngokubanzi kwe-EMC kwizicelo ezahlukeneyo zemizi-mveliso, ezifana nezinyibilikisi, iingubo, iiplastiki, iirasi, iziqholo, kunye namayeza. Ukongeza, ngophuhliso loqoqosho lwehlabathi kunye nokuphuculwa kwemigangatho yokuphila kwabantu, imfuno ye-EMC nayo iyanda ngokuthe ngcembe.

Okwangoku, eyona mimandla yabathengi iphambili kwimakethi ye-EMC ibandakanya indawo yaseAsia Pacific, iYurophu, kunye noMntla Melika. Ummandla waseAsia Pacific ngowona mmandla uphambili wabathengi kwimakethi ye-methyl ethyl carbonate, kunye neTshayina, iJapan, kunye noMzantsi Korea abavelisi abaphambili kunye nabathengi be-EMC. Imakethi ye-EMC eYurophu naseMntla Melika nayo ikhula ngokuthe ngcembe, kunye neJamani, i-United Kingdom, i-United States, kunye neCanada ingabathengi abaphambili be-EMC.

Kwixesha elizayo, ukukhula kwemarike ye-EMC kuya kuphenjelelwa luphuhliso loqoqosho lwehlabathi kunye noshishino. Ngokunyuka kweemarike ezivelayo kunye nenkqubela phambili yetekhnoloji eqhubekayo, imfuno ye-EMC kwimarike iya kuqhubeka ikhula. Ukongeza, ukukhuselwa kokusingqongileyo kunye nophuhliso oluzinzileyo luya kuba yimizila ebalulekileyo kwimarike ye-EMC, ukukhuthaza ukuveliswa kunye nokusetyenziswa kwe-EMC ukuba ibe nobungane ngakumbi nokuzinzileyo.
