Dimethyl Carbonate

Mahele ʻEkahi: Ka wehewehe ʻana o  Dimethyl carbonate (DMC)

ʻO ka wai aniani ʻaʻohe waihoʻoluʻu me ka ʻala ʻala. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka ether. Ka mea i kapaia DMC, Methyl Carbonate, Methyl Carbonate, Dimetyl Carbonate, Dimethyl Carbonate.CAS No.616-38-6, EINECS:210-478-4 Chemical Formula:C3H6O3

Mahele ʻElua Ka hoʻohana ʻana o Dimethyl carbonate (DMC)

1. Pena, ka uhi a me ka ʻoihana hoʻopili

Ma muli o kona hoʻoheheʻe maikaʻi ʻana, nā pae hoʻoheheʻe a me ka paila ʻana, nui ka ʻili o ka ʻili, haʻahaʻa viscosity, a me ka liʻiliʻi dielectric mau, hiki i ka dimethyl carbonate ke hoʻololi i nā toluene a me nā huahana xylene a hoʻohana nui ʻia i nā pena kiʻekiʻe, nā uhi, adhesives, etc. Glue a me nā ʻoihana ʻē aʻe.

2. ʻOihana Polycarbonate

Hoʻohana nui ʻia ʻo Dimethyl carbonate i nā ʻano kūlohelohe like ʻole a hoʻololi mālie i ka phosgene i ka hana ʻana o ka polycarbonate a me ka isocyanate, nona kahi ākea mākeke nui. ʻO ka Polycarbonate kahi mea maʻamau i kēlā me kēia lā me ke kūpaʻa hopena koʻikoʻi. ʻO ia wale nō ka huahana me ke aniani maikaʻi ma waena o nā plastics ʻenekinia nui ʻelima. ʻO ia hoʻi ka wikiwiki e ulu nei i ka plastic engineering maʻamau i nā makahiki i hala iho nei. Hoʻohana nui ʻia ia i kēia manawa i nā kaʻa, nā uila a me nā uila, ke kūkulu ʻana, nā lako keʻena, ka ʻeke, nā mea haʻuki, ka mālama olakino a me nā ʻoihana ʻē aʻe. Me ka hoʻomau mau ʻana o ka noiʻi hoʻololi ʻana, ke hoʻonui wikiwiki nei ia i nā kahua ʻenehana kiʻekiʻe e like me ka aerospace, computers, optical discs a pēlā aku.

3. Lithium-ion pākahi electrolyte

Me ka hoʻokō mau ʻana o ka hoʻolālā ʻoihana ikehu hou o ka ʻāina, nā mopeds uila a me nā mākeke kaʻa uila, ma lalo o ke alakaʻi ʻana o ka hoʻolālā ikehu hou aupuni, lilo ʻo Dimethyl carbonate i hoʻokahi o nā ʻoihana me ka nui o ka mākeke ma koʻu ʻāina i ka wā e hiki mai ana. Pēlā nō, ua hoʻonui pū ʻia ka hoʻopuka a me ke koi o ka ʻoihana pākaukau lithium. ʻO ka ulu wikiwiki. E like me kekahi o nā kumu waiwai nui no ka electrolyte pākaukau, e ulu wikiwiki nā huahana carbonate i ka noi ma ke kahua o nā pā lithium.

4. Nā mea hoʻohui aila

Ma muli o kona kiʻekiʻe o ka oxygen maʻiʻo (oxygen content 53%, ʻekolu mau manawa o ka MTBE) a me ke kaomi mahu kūpono, ka pale ʻana i ka wai a me ka hui pū ʻana i ka coefficient, hiki ke hoʻohana ʻia ʻo Dimethyl carbonate i mea hoʻohui maikaʻi / diesel e hoʻoikaika i ka puhi ahi a hoʻonui i ka octane. waiwai, hoemi kalapona emissions, a ma ka ia manawa hoʻomaikaʻi i ka anti-kikeke hana o ka 'aila/diesel.

5. ʻoihana lāʻau lapaʻau

ʻO ka ʻoihana lāʻau lapaʻau i kēia manawa he wahi hoʻohana nui no ka dimethyl carbonate i koʻu ʻāina. I ka lāʻau lapaʻau, hoʻohana nui ʻia ka dimethyl carbonate ma ke ʻano he methylating agent e hoʻololi i ka dimethyl sulfate nui loa, a hoʻohana ʻia e synthesize i nā lāʻau anti-infective, antipyretics a me analgesics. nā lāʻau lapaʻau, nā huaora, a me nā lāʻau lapaʻau.

6. Pesticides

ʻO koʻu ʻāina kahi mea hana nui i nā pesticides. Ke piʻi nei ka wikiwiki o ka hoʻoponopono ʻana o ka ʻoihana pesticide o koʻu ʻāina, e ʻoi aku ka koʻikoʻi o nā koi o ka ʻāina no ka palekana pesticide. E hoʻololi mālie ʻia nā lāʻau pesticides kuʻuna ʻawaʻawa loa e nā hua lāʻau ʻawaʻawa ʻole a haʻahaʻa. No laila, ma ke ʻano he ʻōmaʻomaʻo ʻO ka hoʻohana ʻana i nā huahana dimethyl carbonate intermediate e pili ana i ke kaiapuni i ke kahua o ka hana pesticide e loaʻa i nā manaʻo hoʻomohala ākea.

7. ADC resin

Loaʻa iā Allyl diglycol carbonate (ADC) nā hiʻohiʻona optical maikaʻi loa, ke kūpaʻa ʻaʻahu, ke kūpaʻa bacteria, a me ke kaumaha māmā. He resin thermosetting. Hiki iā ia ke pani i ke aniani a hoʻohana ʻia e like me nā lens spectacle a me nā mea optoelectronic. Ua hana mua ia mai ka propylene alcohol, diethyl glycol a me phosgene. I kēia mau lā, hoʻohana maʻamau ka ʻoihana i ka DMC e pani i ka phosgene. No ka mea he haʻahaʻa haʻahaʻa ka DMC a ʻaʻole corrosive, hoʻemi ia i nā koi ʻenehana i ka hana ʻana i nā mea hana, ka hoʻokele hana a me ka mālama ʻana i nā ʻōpala. ʻO ka mea nui, hiki ke hana maʻalahi nā huahana kiʻekiʻe. No laila, ke wehe ʻia nei nā kahua hou e like me ka hoʻohana ʻana i nā mea pono optoelectronic.
