Ethyl methyl carbonatehe mea hoʻohuihui mea ola me ke ʻano kemika C5H8O3, ʻike ʻia hoʻi ʻo EMC. He wai waihoʻoluʻu ʻole, ʻikea, a me ka liʻiliʻi me ka haʻahaʻa haʻahaʻa a me ka volatility. Hoʻohana maʻamau ʻia ʻo EMC ma ke ʻano he mea maka i nā kula e like me nā solvents, coatings, plastics, resins, spices, a me pharmaceuticals. Hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā pūhui organik ʻē aʻe, e like me ka polycarbonate. I ka hana ʻoihana, hana maʻamau ka hana ʻana o EMC i ka hopena ester exchange a i ʻole ka hopena esterification carbonation.

Ka inoa huahana: Ethyl methyl carbonate

CAS:623-53-0

Huina molekala:C4H8O3

EINECS:433-480-9

ʻO ka papa noi haʻahaʻa o EMC ka nui o ka lithium-ion battery electrolyte, ʻo ia kekahi o nā mea nui ʻehā o nā pā lithium-ion a ʻike maopopo ʻia ʻo ke "koko" o nā pā.

Ua hoʻokaʻawale ʻia ʻo EMC i ʻelua mau ʻāpana e pili ana i ka maʻemaʻe: ʻoihana methyl ethyl carbonate (99.9%) a me ka helu pākaukau EMC (99.99% a ʻoi aku paha). Hoʻohana nui ʻia ka EMC papa hana i ka synthesis organik a me nā solvents; Pono ke kaʻina hana EMC i nā koi kiʻekiʻe a hoʻohana nui ʻia ma ke ʻano he solvent no nā electrolytes pākaukau lithium-ion. Ma muli o kona liʻiliʻi steric hindrance a me ka asymmetry i ka hoʻolālā, hiki iā ia ke kōkua i ka hoʻonui ʻana i ka solubility o nā ion lithium, ka hoʻomaikaʻi ʻana i ka capacitance density a me ka hoʻopiʻi ʻana o ka pākaukau, a ua lilo ia i hoʻokahi o nā mea hoʻoheheʻe nui ʻelima no nā electrolytes pākahi lithium-ion.

ʻO ka papa noi haʻahaʻa o EMC ka nui o ka lithium-ion battery electrolyte, ʻo ia kekahi o nā mea nui ʻehā o nā pā lithium-ion a ʻike maopopo ʻia ʻo ke "koko" o nā pā. I nā makahiki i hala iho nei, me ka hoʻomohala wikiwiki ʻana o ka ʻoihana kaʻa ikehu hou, ua komo ka ʻoihana electrolyte pākahi lithium-ion o Kina i kahi manawa o ka ulu wikiwiki. Ua hoʻonui nui ʻia ka helu localization o nā electrolytes, a ua hoʻokō maoli ʻia ka hoʻololi ʻana i ka lawe ʻana mai, e alakaʻi ana i ka ulu wikiwiki o ka noi no EMC ma ka mākeke o Kina. Wahi a ka "2023-2027 China EMC Industry Market Deep Research and Development Prospects Forecast Report" i hoʻokuʻu ʻia e ka Xinsijie Industry Research Center, i ka makahiki 2021, ʻo ka noi no EMC ma Kina he 139500 tons, kahi hoʻonui makahiki o 94.7% .

ʻO ka mākeke noEMCua hōʻike i kahi ulu paʻa i nā makahiki i hala iho nei. ʻO kēia ma muli o ka hoʻohana nui ʻana o EMC i nā noi ʻoihana like ʻole, e like me nā solvents, coatings, plastics, resins, spices, a me pharmaceuticals. Eia kekahi, me ka hoʻomohala ʻana o ka hoʻokele honua a me ka hoʻomaikaʻi ʻana i nā kūlana ola o ka poʻe, ke piʻi mālie nei ka noi no EMC.

I kēia manawa, ʻo nā wahi mea kūʻai nui o ka mākeke EMC e pili ana i ka ʻāina ʻo Asia Pacific, ʻEulopa, a me ʻAmelika ʻAmelika. ʻO ka ʻāina ʻo Asia Pacific ka mea kūʻai nui o ka mākeke methyl ethyl carbonate, me Kina, Iapana, a me South Korea ka mea hana nui a me nā mea kūʻai aku o EMC. Ke ulu mālie nei ka mākeke no EMC ma ʻEulopa a me ʻAmelika ʻAmelika, me Kelemania, United Kingdom, ʻAmelika Hui Pū ʻIa, a me Kanada ka mea kūʻai nui o EMC.

I ka wā e hiki mai ana, e hoʻopili ʻia ka ulu ʻana o ka mākeke EMC e ka hoʻokele waiwai a me ka hoʻomohala ʻenehana. Me ka piʻi ʻana o nā mākeke e kū mai ana a me ka holomua ʻenehana hoʻomau, e ulu mau ka noi no EMC i ka mākeke. Eia kekahi, ʻo ka mālama ʻana i ke kaiapuni a me ka hoʻomohala hoʻomau e lilo i mau ʻano koʻikoʻi i ka mākeke EMC, e hāpai ana i ka hana ʻana a me ka hoʻohana ʻana i ka EMC i ʻoi aku ka maikaʻi o ke kaiapuni a hoʻomau.
