Ethyl methyl carbonatendi organic pawiri yokhala ndi formula yamankhwala C5H8O3, yomwe imadziwikanso kuti EMC. Ndi madzi opanda mtundu, owonekera, komanso osasunthika okhala ndi kawopsedwe kakang'ono komanso kusakhazikika. EMC imagwiritsidwa ntchito ngati zopangira m'minda monga zosungunulira, zokutira, mapulasitiki, utomoni, zonunkhira, ndi mankhwala. Itha kugwiritsidwanso ntchito pokonzekera mankhwala ena achilengedwe, monga polycarbonate. Popanga mafakitale, kupanga kwa EMC nthawi zambiri kumatengera kusinthana kwa ester kapena carbonation esterification reaction.

Dzina lazogulitsa: Ethyl methyl carbonate

CAS:623-53-0

Molecular formula: C4H8O3

EINECS: 433-480-9

Malo ogwiritsira ntchito kumunsi kwa EMC ndi electrolyte ya lithiamu-ion batire, yomwe ndi imodzi mwazinthu zinayi zazikulu zamabatire a lithiamu-ion ndipo imatchulidwa momveka bwino kuti "magazi" a mabatire.

EMC imagawidwa m'magulu awiri kutengera chiyero: mafakitale kalasi methyl ethyl carbonate (99.9%) ndi batire kalasi EMC (99.99% kapena apamwamba). Industrial kalasi EMC zimagwiritsa ntchito mafakitale organic synthesis ndi solvents; Batire kalasi EMC ndondomeko amafuna apamwamba zofunika ndipo makamaka ntchito monga zosungunulira kwa lithiamu-ion batire electrolytes. Chifukwa chaching'ono chotchinga chotchinga ndi asymmetry mu dongosolo, angathandize kuonjezera solubility wa ayoni lifiyamu, kuwongolera capacitance kachulukidwe ndi mlandu wa batire, ndipo wakhala chimodzi mwa zisanu zosungunulira waukulu electrolytes lithiamu-ion batire.

Malo ogwiritsira ntchito kumunsi kwa EMC ndi electrolyte ya lithiamu-ion batire, yomwe ndi imodzi mwazinthu zinayi zazikulu zamabatire a lithiamu-ion ndipo imatchulidwa momveka bwino kuti "magazi" a mabatire. M'zaka zaposachedwa, ndi chitukuko chofulumira chamakampani opanga magalimoto amphamvu, makampani aku China a lithiamu-ion batire electrolyte adalowa m'nthawi yachitukuko chofulumira. Kuchulukitsa kwa ma electrolyte kwakwera kwambiri, ndipo kulowetsedwa m'malo kwatheka, zomwe zikuyendetsa kukula kwachangu kwa EMC pamsika waku China. Malinga ndi "2023-2027 China EMC Industry Market Deep Research and Development Prospects Forecast Report" yotulutsidwa ndi Xinsijie Industry Research Center, mu 2021, kufunikira kwa EMC ku China kunali matani 139500, kuwonjezeka kwa chaka ndi 94.7% .

Msika waMtengo wa EMCyawonetsa chiwonjezeko chokhazikika m'zaka zingapo zapitazi. Izi zimachitika makamaka chifukwa cha kufalikira kwa EMC m'mafakitale osiyanasiyana, monga zosungunulira, zokutira, mapulasitiki, utomoni, zonunkhira, ndi mankhwala. Kuphatikiza apo, pakutukuka kwachuma padziko lonse lapansi komanso kusintha kwa moyo wa anthu, kufunikira kwa EMC kukuchulukiranso pang'onopang'ono.

Pakadali pano, madera ogula kwambiri pamsika wa EMC akuphatikiza dera la Asia Pacific, Europe, ndi North America. Dera la Asia Pacific ndiye dera lalikulu la msika wa methyl ethyl carbonate, pomwe China, Japan, ndi South Korea ndi omwe amapanga komanso ogula kwambiri a EMC. Msika wa EMC ku Europe ndi North America ukukulanso pang'onopang'ono, Germany, United Kingdom, United States, ndi Canada kukhala ogula kwambiri a EMC.

M'tsogolomu, kukula kwa msika wa EMC kudzakhudzidwa ndi chitukuko cha zachuma ndi mafakitale. Ndi kukwera kwamisika yomwe ikubwera komanso kupita patsogolo kwaukadaulo, kufunikira kwa EMC pamsika kukupitilira kukula. Kuphatikiza apo, kuteteza chilengedwe ndi chitukuko chokhazikika kudzakhalanso njira zofunika kwambiri pamsika wa EMC, kulimbikitsa kupanga ndi kugwiritsa ntchito EMC kuti ikhale yosamalira zachilengedwe komanso yokhazikika.
