Hoʻohana ʻia ʻo 1.1,3-Dimethyl-2-imidazolidinone e aʻo i nā ʻāpana metala hoʻololi hydrosilane dibasic i hoʻopaʻa ʻia e ka hoʻokumu ʻana o ka photochemical o nā aryl silanes.
2. Hoʻohana pinepine ʻia ka mea hoʻoheheʻe dipolar Aprotic, 1,3-dimethyl-2-imidazolidinone ma ke ʻano he pani HMPA carcinogen.
3. Mea hoʻoheheʻe hopena
Ma muli o kona kūpaʻa wela a me ke kemika maikaʻi loa, loaʻa iā DMI ka solubility i nā hui inorganic, organic a me nā resins like ʻole, a ʻo kona hopena catalytic ma ke ʻano he solvent polar non-protonic e hoʻolilo iā ia i mea hoʻoheheʻe hopena kūpono loa. . Ke hoʻohana nei iā DMI, hiki ke hoʻomaikaʻi ʻia ka hua a hiki ke hoʻomalu pono ʻia nā hopena ʻaoʻao me ka hoʻopōkole ʻana i ka manawa hopena.
Hiki i ka DMI ke hoʻolaha pono i nā ʻano hana hoʻololi nucleophilic like ʻole, e like me ka synthesis o nā phenyl ether derivatives, nā pūhui amino a me nā fluorobenzene derivatives. ʻO kona dielectric constant kiʻekiʻe a me ka cationic solvation hiki ke hoʻoulu i nā hopena nucleophilic anionic. Hoʻohana ʻia kēia mau huahana synthetic ma ke ʻano he mau waena no ka synthesis o nā pesticides, nā lāʻau lapaʻau, nā dyes a me nā monomers resin hana kiʻekiʻe.
4. Nā huahana ʻaila
He kiʻekiʻe ke kiko paila o DMI a he kiʻekiʻe ke kūpaʻa wela, a ʻaʻole maʻalahi ke hana i nā azeotropes me nā mea ʻē aʻe. No laila, hiki ke hoʻohana ʻia i nā kaʻina hana he nui e like me ka unuhi wai-wai, ka hoʻolaha countercurrent, ka distillation extractive a me ka holoi countercurrent. He mea hoʻoheheʻe BTX (benzene, toluene a me xylene) maikaʻi ʻo DMI no ka mea hoʻoheheʻe ia i nā hui ʻala a me nā hydrocarbons unsaturated, akā ʻaʻole hoʻoheheʻe i ka paraffin.
5. Mea hoʻoheheʻe hana polymer
ʻO DMI wale nō ka mea hoʻoheheʻe i hoʻohana ʻia e hana i nā thermoplastics kūpaʻa wela. Hoʻohana pono ʻia hoʻi ia ma ke ʻano he mea hoʻoheheʻe no nā kaʻina hana synthesis polymer like ʻole a me kahi mea holoi no ka polymerization a me ka hoʻoheheʻe plastik. I ka hana ʻana o nā resins polyamide a me polyimide, hoʻolalelale ʻo DMI i ka hoʻokumu ʻana o nā hui amide a me imine e loaʻa ai nā polymers kaumaha molekala kiʻekiʻe, a kūpono ka hopena hopena no ka milo ʻana o ka hopena e loaʻa ai nā olonā polyimide kūpaʻa wela kiʻekiʻe.
I ka hana ʻana o ka polyphenylene sulfide resin (PPS), hiki ke loaʻa nā mea uila me nā liʻiliʻi liʻiliʻi o nā haumia organik e DMI. I ka hana ʻana o ka polyphenylene ether sulfone resin, hiki iā DMI ke kāohi pono i ka hanana o nā hopena ʻaoʻao a loaʻa nā huahana polymer kiʻekiʻe. Ke hoʻokumu ʻia ka polyimide resin a me ka polysulfone resin i loko o nā kiʻiʻoniʻoni a hoʻolōʻihi ʻia nā kiʻiʻoniʻoni polyether ketone resin, hiki i ka mālama ʻana me DMI ke hoʻolilo i nā kiʻiʻoniʻoni i ʻoi aku ka like.
6. Mea hoʻokaʻawale kaʻina hana photolithography
Ma muli o kona viscosity haʻahaʻa a me ke kūpaʻa dielectric kiʻekiʻe, hiki ke hoʻohana ʻia ʻo DMI ma ke ʻano he mea hoʻoheheʻe electrolyte no nā pila lithium hana kiʻekiʻe. Eia kekahi, he permeability ikaika kona, he kiko paila kiʻekiʻe a he kūpaʻa wela kiʻekiʻe, a hiki ke hoʻohana ʻia ma ke ʻano he mea kahakaha no ka photoresist wafer silicon. ʻO kona mau waiwai wikiwiki a me nā waiwai ʻaʻole corrosive e hoʻomaʻalahi nui i ke kaʻina hana kahakaha a hoʻolalelale i ka huahana o ka ʻoki ʻana i nā ʻāpana.
7. Mea holoi lole
Hoʻohui ʻia ʻo DMI i ka hui ʻana o nā surfactants, alkalis, alcohols a me polyoxyethylene alkyl ethers e loaʻa ai kahi detergent ikaika. ʻOiai he maʻalahi loa ka hoʻoheheʻe ʻana o ka DMI i ka lepo, hiki ke hoʻohana ʻia e hoʻomākaukau i nā hopena hoʻomaʻemaʻe kūpono no ka hoʻomaʻemaʻe ʻana i ke aniani a me ka metala.
8. Nā kala a me nā pigments
Hiki ke paʻi ʻia nā ʻīnika i hana ʻia ma ke kāwili ʻana iā DMI me nā ʻāpana solvent a me nā dyes a me nā pigments ma ke ʻano ʻokoʻa, a ua akāka ke kiʻi.
9. Mea hana lapaʻau ʻili
Hiki ke hoʻohana ʻia ʻo DMI ma ke ʻano he mea lapaʻau ʻili e hoʻomaikaʻi i ka ikaika hoʻopaʻa o ABS, polyimide, PPS, Teflon a me nā mea ʻē aʻe me nā mea hoʻopili epoxy resin.
