Ethyl methyl carbonateimusanganiswa weorganic une fomura yemakemikari C5H8O3, inozivikanwawo seEMC. Imvura isina ruvara, yakajeka, uye inoshanduka-shanduka ine chepfu shoma uye kusagadzikana. EMC inowanzoshandiswa sechinhu chisina kugadzirwa muminda yakaita se solvents, coatings, plastics, resin, spices, uye mishonga. Inogona zvakare kushandiswa kugadzira mamwe makemikari eorganic, akadai se polycarbonate. Mukugadzirwa kwemaindasitiri, kugadzirwa kweEMC kunowanzo tora ester exchange reaction kana carbonation esterification reaction.
Zita rechigadzirwa: Ethyl methyl carbonate
CAS：623-53-0
Fomura yeMorekuru：C4H8O3
EINECS：433-480-9
Nzvimbo yekushandiswa kweEMC inonyanya kushandiswa nebhatiri re lithium-ion electrolyte, inova imwe yezvinhu zvikuru zvina zvemabhatiri e lithium-ion uye inozivikanwa zvakajeka se "ropa" remabhatiri.
EMC yakakamurwa kuita mapoka maviri zvichibva pakuchena kwayo: methyl ethyl carbonate yemhando yeindasitiri (99.9%) uye EMC yemhando yebhatiri (99.99% kana kupfuura). EMC yemhando yeindasitiri inonyanya kushandiswa mukugadzirwa kwezvinhu zvemaindasitiri uye zvinonyungudutsa; Maitiro eEMC yemhando yebhatiri anoda zvinodiwa zvakanyanya uye anonyanya kushandiswa semushonga we electrolytes dzebhatiri re lithium-ion. Nekuda kwekusagadzikana kwayo kudiki uye kusafanana muchimiro, inogona kubatsira mukuwedzera kunyunguduka kwema lithium ions, kuvandudza huwandu hwe capacitance uye chaji yebhatiri, uye yave imwe yezvinyungudutsa zvishanu zvikuru zve lithium-ion battery electrolytes.
Nzvimbo yekushandiswa kweEMC inonyanya kushandisa lithium-ion battery electrolyte, inova imwe yezvinhu zvina zvikuru zvemabhatiri e lithium-ion uye inozivikanwa zvakajeka se "ropa" remabhatiri. Mumakore achangopfuura, nekukura nekukurumidza kweindasitiri itsva yemotokari dzemagetsi, indasitiri ye electrolyte yemabhatiri e lithium-ion muChina yakapinda munguva yekukura nekukurumidza. Mwero wenzvimbo yema electrolyte wakawedzera zvakanyanya, uye kutsiva kwekunze kwave kuwanikwa, zvichikonzera kukura nekukurumidza kwekudiwa kweEMC mumusika weChina. Sekureva kwe "2023-2027 China EMC Industry Market Deep Research and Development Prospects Forecast Report" yakaburitswa neXisijie Industry Research Center, muna 2021, kudiwa kweEMC muChina kwaive matani 139500, kuwedzera kwegore negore kwe94.7%.
Musika weEMCyakaratidza kukura kwakasimba mumakore mashoma apfuura. Izvi zvinonyanya kukonzerwa nekushandiswa kwakapararira kweEMC mumaindasitiri akasiyana-siyana, akadai sezvinonyungudutsa, machira, mapurasitiki, maresini, zvinonhuwira, uye mishonga. Pamusoro pezvo, nekukura kwehupfumi hwenyika uye kuvandudzwa kwemararamiro evanhu, kudiwa kweEMC kuri kuwedzerawo zvishoma nezvishoma.
Parizvino, nzvimbo huru dzevatengi mumusika weEMC dzinosanganisira dunhu reAsia Pacific, Europe, neNorth America. Dunhu reAsia Pacific ndiro dunhu guru revatengi vemethyl ethyl carbonate, neChina, Japan, neSouth Korea dziri ivo vagadziri vakuru nevatengi veEMC. Musika weEMC muEurope neNorth America uri kukurawo zvishoma nezvishoma, neGermany, United Kingdom, United States, neCanada dziri ivo vanonyanya kushandisa EMC.
Mune ramangwana, kukura kwemusika weEMC kuchakanganiswa nekukura kwehupfumi hwenyika nemaindasitiri. Nekukura kwemisika iri kubuda uye kufambira mberi kwetekinoroji kuri kuramba kuchienderera mberi, kudiwa kweEMC mumusika kucharamba kuchikura. Pamusoro pezvo, kuchengetedzwa kwezvakatipoteredza nekuvandudzwa kunoenderera mberi zvichavewo mafambiro akakosha mumusika weEMC, zvichikurudzira kugadzirwa nekushandiswa kweEMC kuti ive ine hushamwari kune zvakatipoteredza uye igare kwenguva refu.
