1,3-Dimethyl-2-imidazolidinone CAS 80-73-9

E whakamahia ana te 1.1,3-Dimethyl-2-imidazolidinone hei ako i ngā matatini whakarewa whakawhiti hydrosilane dibasic kua mahihia, kua whakauhia mā te hanganga whakaahua o ngā aryl silanes.

2. Ko te whakarewa aporotic dipolar, 1,3-dimethyl-2-imidazolidinone, e whakamahia pinepine ana hei whakakapinga HMPA carcinogen.

3. Te whakarewa tauhohenga

Nā te tino pai o te pumau o te wera me te matū, ka taea e te DMI te wairewa i roto i ngā matū waro-kore, waro me ngā momo kapia, ā, ko tōna pānga whakaterenga hei whakarewa pōro kore-protonic he mea tino whai hua hei whakarewa tauhohenga. Mā te whakamahi i te DMI, ka taea te whakapai ake i te hua, ā, ka taea te whakahaere pai i ngā tauhohenga taha me te whakapoto i te wā tauhohenga.

Ka taea e te DMI te whakatairanga i ngā tauhohenga whakakapinga nucleophilic, pērā i te hanga o ngā phenyl ether derivatives, ngā amino compounds me ngā fluorobenzene derivatives. Mā tōna pūmau dielectric teitei me te whakarewa cationic ka taea te whakakorikori i ngā tauhohenga nucleophilic anionic. Ka whakamahia ēnei hua hanga hei takawaenga mō te hanga o ngā patupatu pepeke, ngā rongoā, ngā tae me ngā monomers resin mahi-teitei.

4. Ngā hua hinu

He teitei te pāmahana o te DMI, ā, he tino pumau hoki, ā, ehara i te mea ngāwari ki te hanga azeotropes me ētahi atu matū. Nō reira, ka taea te whakamahi i roto i ngā tukanga ahumahi maha pērā i te tango wai-wai, te tohatoha au-whakamuri, te whakahoro tango me te horoi au-whakamuri. He pai te DMI hei tango BTX (benzene, toluene me te xylene) nā te mea ka whakarewa i ngā matū kakara me ngā hauwaiwai kore-mākū, engari kāore e whakarewa i te paraffin.

5. Te whakarewa tauhohenga polima

Ko te DMI anake te whakarewa e whakamahia ana hei hanga i ngā kirihou wera-ātete. He whai hua hoki te whakamahinga hei whakarewa mō ngā tukanga hanga pūmua me te hopi horoi mō te whakapūmua me te hanga kirihou. I roto i te hanga o ngā kapia polyamide me te polyimide, ka tere ake te hanganga o ngā rōpū amide me te imine e te DMI hei whiwhi i ngā pūmua taumaha-ngota teitei, ā, he pai te otinga hua mō te huri i te otinga hei whiwhi i ngā muka polyimide e ātete ana ki te pāmahana teitei.

I roto i te hanga o te kapia polyphenylene sulfide (PPS), ka taea te tiki rauemi hiko me te iti rawa o ngā poke rauropi mā te DMI. I roto i te hanga o te kapia polyphenylene ether sulfone, ka taea e te DMI te whakahaere pai i te putanga mai o ngā tauhohenga taha me te whiwhi hua polymer kounga teitei. Ina hangaia te kapia polyimide me te kapia polysulfone hei kiriata, ā, ina totorohia ngā kiriata kapia polyether ketone, ka taea e te maimoatanga ki te DMI te hanga i ngā kiriata kia ōrite ake.

6. Kaiwhakakore tukanga whakaahua

Nā te iti o te matotoru me te teitei o te pūmau dielectric, ka taea te whakamahi i te DMI hei whakarewa electrolyte mō ngā pākahiko lithium mahi teitei. Hei tāpiri, he kaha te uruhanga, he teitei te ira kohua me te ātete pāmahana teitei, ā, ka taea hoki te whakamahi hei taputapu tango mo te photoresist wafer silicon. Ko ōna āhuatanga tango tere me te kore-waikura ka tino whakangawari i te tukanga tango me te tere ake i te hua o te tapahi maramara.

7. Hopi horoi

Ka tāpirihia te DMI ki te ranunga o ngā surfactants, ngā alkalis, ngā waipiro me ngā polyoxyethylene alkyl ethers hei hanga i tētahi hopi horoi kaha. Nā te mea he tino ngāwari te whakarewa i te paru o te DMI, ka taea hoki te whakamahi hei whakarite i ngā otinga horoi whai hua mō te horoi i te karāhe me te konganuku.

8. Ngā tae me ngā tae whakakoi

Ka taea te tā i ngā waituhi i hangaia mā te whakaranu i te DMI me ngā wāhanga whakarewa me ngā tae me ngā pūtu me te rerekētanga, ā, ka mārama te ahua.

9. Kaihoko maimoatanga mata

Ka taea te whakamahi i te DMI hei kaihoko maimoatanga mata hei whakapai ake i te kaha here o te ABS, te polyimide, te PPS, te Teflon me ētahi atu rauemi mā te whakamahi i ngā piripiri kapia epoxy.
