Ethyl methyl carbonateke motsoako oa manyolo o nang le foromo ea lik'hemik'hale C5H8O3, e tsejoang hape e le EMC. Ke mokelikeli o se nang 'mala, o bonaletsang, le ho fetoha ha maemo a nang le chefo e tlase le ho fetoha ha maemo. EMC e atisa ho sebelisoa e le thepa e tala masimong a kang solvents, coatings, polasetiki, resin, linoko le meriana. E ka boela ea sebelisoa ho lokisa metsoako e meng ea manyolo, joalo ka polycarbonate. Tlhahisong ea indasteri, tlhahiso ea EMC hangata e nka ester exchange reaction kapa carbonation esterification reaction.

Lebitso la sehlahisoa: Ethyl methyl carbonate

Sebaka sa ts'ebeliso ea EMC e tlase haholo ke lithium-ion battery electrolyte, e leng e 'ngoe ea lisebelisoa tse' nè tse kholo tsa libeteri tsa lithium-ion 'me ka ho hlaka e bitsoa "mali" a libeteri.

EMC e arotsoe ka mekhahlelo e 'meli e ipapisitseng le bohloeki: boemo ba indasteri methyl ethyl carbonate (99.9%) le boemo ba betri EMC (99.99% kapa ho feta). EMC ea boemo ba indasteri e sebelisoa haholo ho liindasteri tsa organic synthesis le solvents; Ts'ebetso ea EMC ea boemo ba betri e hloka litlhoko tse phahameng mme e sebelisoa haholo-holo e le solvent bakeng sa li-electrolyte tsa betri tsa lithium-ion. Ka lebaka la tšitiso ea eona e nyane ea steric le asymmetry ka sebopeho, e ka thusa ho eketsa ho qhibiliha ha lithium ion, ho ntlafatsa letsoalo la capacitance le tefiso ea betri, 'me e fetohile e' ngoe ea li-solvents tse hlano tse kholo bakeng sa li-electrolyte tsa betri tsa lithium-ion.

Sebaka sa ts'ebeliso ea EMC e tlase haholo ke lithium-ion battery electrolyte, e leng e 'ngoe ea lisebelisoa tse' nè tse kholo tsa libeteri tsa lithium-ion 'me ka ho hlaka e bitsoa "mali" a libeteri. Lilemong tsa morao tjena, ka tsoelo-pele e potlakileng ea indasteri e ncha ea likoloi, indasteri ea China ea lithium-ion battery electrolyte e kene nakong ea tsoelo-pele e potlakileng. Sekhahla sa li-electrolyte tsa lehae se eketsehile haholo, 'me phetisetso ea kantle ho naha e fihletsoe, e tsamaisang kholo e potlakileng ea tlhoko ea EMC' marakeng oa China. Ho ea ka "2023-2027 China EMC Industry Deep Research and Development Prospects Forecast Report" e lokollotsoeng ke Xinsijie Industry Research Center, ka 2021, tlhokahalo ea EMC Chaena e ne e le lithane tse 139500, keketseho ea selemo le selemo ea 94.7% .

Mmaraka bakeng saEMCe bontshitse tshekamelo ya kgolo e tsitsitseng dilemong tse mmalwa tse fetileng. Sena se bakoa haholo ke ts'ebeliso e atileng ea EMC lits'ebetsong tse fapaneng tsa indasteri, joalo ka li-solvents, likoahelo, lipolasetiki, li-resin, linoko le meriana. Ho feta moo, ka nts'etsopele ea moruo oa lefats'e le ntlafatso ea maemo a bophelo a batho, tlhoko ea EMC le eona e ntse e eketseha butle-butle.

Hajoale, libaka tse kholo tsa bareki ba 'maraka oa EMC li kenyelletsa sebaka sa Asia Pacific, Europe le Amerika Leboea. Sebaka sa Asia Pacific ke sebaka se ka sehloohong sa bareki ba 'maraka oa methyl ethyl carbonate, moo China, Japane le Korea Boroa e leng tsona bahlahisi le bareki ba ka sehloohong ba EMC. Mmaraka oa EMC oa Europe le Amerika Leboea le ona o ntse o hola butle-butle, ha Jeremane, United Kingdom, United States le Canada e le tsona bareki ba ka sehloohong ba EMC.

Nakong e tlang, kholo ea 'maraka oa EMC e tla susumetsoa ke nts'etsopele ea moruo le indasteri ea lefats'e. Ka keketseho ea mebaraka e ntseng e hola le tsoelo-pele e tsoelang pele ea theknoloji, tlhoko ea EMC 'marakeng e tla tsoela pele ho hola. Ho feta moo, tshireletso ya tikoloho le ntshetsopele ya moshwelella le tsona di tla fetoha ditlwaelo tsa bohlokwa mmarakeng wa EMC, ho kgothalletsa tlhahiso le tshebediso ya EMC hore e be e baballang tikoloho le ho tshwarella.
