iindaba

I-ethyl methyl carbonateyi-organic compound enefomyula yekhemikhali i-C5H8O3, ekwaziwa ngokuba yi-EMC. Lulwelo olungenambala, olucacileyo, noluguquguqukayo olunetyhefu ephantsi kunye nokuguquguquka okuncinci. I-EMC isetyenziswa rhoqo njengezinto eziluhlaza kwiinkalo ezifana nezinyibilikisi, iingubo, iiplastiki, iiresini, iziqholo, kunye namayeza. Ingasetyenziselwa nokulungiselela ezinye iikhompawundi ze-organic, ezifana ne-polycarbonate. Kwimveliso yemizi-mveliso, imveliso ye-EMC idla ngokusebenzisa i-ester exchange reaction okanye i-carbonation esterification reaction.

Indawo esezantsi yesicelo se-EMC ikakhulu yi-lithium-ion battery electrolyte, enye yezinto ezine eziphambili zeebhetri ze-lithium-ion kwaye ibizwa ngokucacileyo ngokuba "ligazi" leebhetri.

I-EMC yahlulwe yangamacandelo amabini ngokusekelwe kubumsulwa: i-methyl ethyl carbonate yezinga loshishino (99.9%) kunye ne-EMC yezinga lebhetri (99.99% nangaphezulu). I-EMC yezinga loshishino isetyenziswa kakhulu kwi-industrial organic synthesis kunye ne-solvents; Inkqubo ye-EMC yezinga lebhetri ifuna iimfuno eziphezulu kwaye isetyenziswa kakhulu njenge-solvent ye-lithium-ion battery electrolytes. Ngenxa yokuphazamiseka kwayo okuncinci kwe-steric kunye ne-asymmetry kwisakhiwo, inokunceda ekwandiseni ukunyibilika kwee-lithium ions, ukuphucula uxinano lwe-capacitance kunye ne-charge yebhetri, kwaye ibe yenye ye-solvents ezintlanu eziphambili ze-lithium-ion battery electrolytes.

Intsimi yokusetyenziswa kwe-EMC ikakhulu yi-lithium-ion battery electrolyte, enye yezinto ezine eziphambili zeebhetri ze-lithium-ion kwaye ibizwa ngokucacileyo ngokuba "ligazi" leebhetri. Kwiminyaka yakutshanje, ngophuhliso olukhawulezayo lweshishini elitsha lezithuthi zamandla, ishishini le-electrolyte leebhetri ze-lithium-ion laseTshayina lingene kwixesha lophuhliso olukhawulezayo. Izinga lokufumana ii-electrolyte liye landa kakhulu, kwaye ukutshintshwa kwezinto ezingeniswa kwamanye amazwe kuye kwafezekiswa ngokusisiseko, nto leyo eqhubela phambili ukukhula okukhawulezileyo kwemfuno ye-EMC kwimarike yaseTshayina. Ngokutsho kwe-"2023-2027 China EMC Industry Market Deep Research and Development Prospects Report" ekhutshwe yiXisijie Industry Research Center, ngo-2021, imfuno ye-EMC eTshayina yayiyi-139500 tons, ukunyuka konyaka nonyaka kwe-94.7%.

Imakethi yeI-EMCibonakalise ukukhula okuzinzileyo kwiminyaka embalwa edlulileyo. Oku kungenxa yokusetyenziswa ngokubanzi kwe-EMC kwizicelo ezahlukeneyo zoshishino, ezifana nezinyibilikisi, iingubo, iiplastiki, iiresini, iziqholo, kunye namayeza. Ukongeza, ngophuhliso loqoqosho lwehlabathi kunye nokuphuculwa kwemigangatho yokuphila yabantu, imfuno ye-EMC nayo iyanda kancinci kancinci.

Okwangoku, iindawo eziphambili zabathengi kwimarike ye-EMC ziquka ummandla we-Asia Pacific, iYurophu, kunye noMntla Melika. Ummandla we-Asia Pacific ngowona mmandla uphambili wabathengi kwimarike ye-methyl ethyl carbonate, kunye neTshayina, iJapan, kunye noMzantsi Korea njengabavelisi kunye nabathengi abaphambili be-EMC. Imarike ye-EMC eYurophu naseMntla Melika nayo ikhula kancinci kancinci, kunye neJamani, i-United Kingdom, i-United States, kunye neKhanada njengabathengi abaphambili be-EMC.

Kwixesha elizayo, ukukhula kwemarike ye-EMC kuya kuphenjelelwa luphuhliso lwezoqoqosho nolwemizi-mveliso lwehlabathi. Ngokukhula kweemarike ezisakhulayo kunye nenkqubela phambili yetekhnoloji eqhubekayo, imfuno ye-EMC kwimarike iya kuqhubeka ikhula. Ukongeza, ukhuseleko lokusingqongileyo kunye nophuhliso oluzinzileyo kuya kuba ziindlela ezibalulekileyo kwimarike ye-EMC, ukukhuthaza ukuveliswa nokusetyenziswa kwe-EMC ukuba ibe nobuhlobo nokusingqongileyo kwaye ihlale izinzile.
