Hoʻohana
ʻO kekahi o nā pōmaikaʻi nui o DMC ʻo ia ka hiki ke hoʻololi i ka phosgene ma ke ʻano he carbonylating agent, e hāʻawi ana i kahi ʻokoʻa palekana a ʻoi aku ka maikaʻi. He pilikia koʻikoʻi ka Phosgene i ke olakino kanaka a me nā kaiaola ma muli o kona ʻona. Ma ka hoʻohana ʻana i ka DMC ma kahi o phosgene, ʻaʻole hiki i nā mea hana ke hoʻomaikaʻi wale i nā kūlana palekana, akā kōkua pū kekahi i kahi kaʻina hana ʻōmaʻomaʻo, maʻemaʻe.
Eia hou, hiki i ka DMC ke lilo i mea hoʻololi maikaʻi loa no ka methylating agent dimethyl sulfate. ʻO ka Dimethyl sulfate kahi mea ʻawaʻawa nui e hoʻopilikia nui i nā limahana a me ke kaiapuni. ʻO ka hoʻohana ʻana iā DMC ma ke ʻano he methylating agent e hoʻopau i kēia mau pilikia me ka hāʻawi ʻana i nā hopena like. Hana kēia i ka DMC i kūpono no nā ʻoihana e hana ana i nā lāʻau lapaʻau, agrochemical, a me nā kemika methyl-critical ʻē aʻe.
Ma waho aʻe o nā pono i ʻōlelo ʻia aʻe nei, ʻoi aku ka maikaʻi o DMC ma ke ʻano he haʻahaʻa haʻahaʻa haʻahaʻa, e lilo ia i koho maikaʻi no nā ʻano noi. ʻO kāna mea ʻawaʻawa haʻahaʻa e hōʻoia i kahi kaiapuni hana palekana, e hōʻemi ana i ka pilikia o ka mea hana a me ka mea kūʻai aku i nā mea ʻino. Eia kekahi, ʻo ka solubility maikaʻi o DMC a me ka laulā ākea me nā mea like ʻole e lilo ia i mea waiwai nui i ka hana ʻana i nā mea hoʻohui. ʻO ka hoʻohana ʻana i ka DMC ma ke ʻano he solvent no nā mea hoʻohui wahie e hoʻomaikaʻi i ka pono o ka puhi ʻana o ka ʻaila, e hōʻemi ana i nā hoʻokuʻu a hoʻomaikaʻi i ka hana ʻenekini.
I ka hopena, ʻo ka dimethyl carbonate (DMC) he mea maʻalahi a hoʻomau i nā mea hoʻohui kuʻuna. ʻO kona palekana, ʻoluʻolu, haʻahaʻa haʻahaʻa a me ka hoʻohālikelike ʻana e hana maikaʻi ʻo DMC no kahi ākea o nā noi. Ma ka hoʻololi ʻana i ka phosgene a me ka dimethyl sulfate, hāʻawi ʻo DMC i kahi koho palekana, ʻoi aku ka ʻōmaʻomaʻo me ka ʻole o ka hoʻokō ʻana i ka hana. Inā hoʻohana ʻia ma ke ʻano he carbonylating agent, methylating agent, a i ʻole solvent haʻahaʻa haʻahaʻa, ʻo DMC kahi hopena hilinaʻi no nā ʻoihana e nānā ana e hoʻomaikaʻi i nā huahana a me nā kaʻina hana ʻoiai e hōʻemi ana i ka hopena o ke kaiapuni.
