Kopo

1.1,3-Dimethyl-2-imidazolidinone e sebedisetswa ho ithuta di-complexes tsa metal transition tsa hydrosilane dibasic tse sebetsang hantle tse tsitsitseng ka ho thehwa ha aryl silanes ka photochemical.

2. Sehlahisoa sa dipolar sa aprotic, 1,3-dimethyl-2-imidazolidinone hangata se sebediswa e le sebaka sa HMPA se bakang kankere.

3. Setharollo sa karabelo

Ka lebaka la botsitso ba eona bo botle ba mocheso le lik'hemik'hale, DMI e na le ho qhibiliha ha metsoako e sa tloaelehang, ea tlhaho le li-resin tse fapaneng, 'me phello ea eona ea catalytic e le tharollo ea polar e seng ea protonic e etsa hore e be tharollo e sebetsang haholo ea karabelo. . Ha re sebelisa DMI, chai e ka ntlafatsoa 'me likarabo tse ka thoko li ka laoloa ka katleho ha ho ntse ho khutsufatsoa nako ea karabelo.

DMI e ka khothaletsa ka katleho liketso tse fapaneng tsa ho nkela sebaka ha nucleophilic, tse kang ho kopanngoa ha li-derivative tsa phenyl ether, metsoako ea amino le li-derivative tsa fluorobenzene. Tharollo ea eona e phahameng ea dielectric e sa fetoheng le cationic e ka susumetsa liketso tsa anionic nucleophilic. Lihlahisoa tsena tsa maiketsetso li sebelisoa e le li-intermediate bakeng sa ho kopanngoa ha chefo e bolaeang likokoanyana, lithethefatsi, lidae le li-monomers tsa resin tse sebetsang hantle.

4. Lihlahisoa tsa peterole

DMI e na le ntlha e phahameng ea ho belisa le botsitso bo phahameng ba mocheso, 'me ha ho bonolo ho etsa azeotropes ka lintho tse ling. Ka hona, e ka sebelisoa lits'ebetsong tse ngata tsa indasteri tse kang ho ntšoa ha metsi le mokelikeli, kabo ea motlakase o khahlanong le motlakase, ho ntšoa ha metsi le ho hlatsoa motlakase o khahlanong le motlakase. DMI ke setlolo se setle sa BTX (benzene, toluene le xylene) hobane se qhala metsoako e nkhang hamonate le li-hydrocarbon tse sa koaheloang, empa ha se qhala parafini.

5. Sethapo sa karabelo ea polymer

DMI ke eona feela tharollo e sebelisetsoang ho hlahisa thermoplastics e hanelang mocheso. E boetse e sebelisoa ka katleho e le tharollo bakeng sa mekhoa e fapaneng ea ho kopanya polymer le sesepa sa ho etsa polymerization le ho bopa polasetiki. Tlhahisong ea li-resin tsa polyamide le polyimide, DMI e potlakisa ho thehoa ha lihlopha tsa amide le imine ho fumana li-polymers tse boima bo phahameng ba limolek'hule, 'me tharollo e hlahisoang e loketse ho ohla tharollo ho fumana likhoele tsa polyimide tse hanelang mocheso o phahameng.

Tlhahisong ea resin ea polyphenylene sulfide (PPS), thepa ea elektroniki e nang le litšila tse nyane haholo tsa tlhaho e ka fumanoa ke DMI. Tlhahisong ea resin ea polyphenylene ether sulfone, DMI e ka laola ka katleho ho hlaha ha likarabelo tse ka thoko le ho fumana lihlahisoa tsa polymer tsa boleng bo holimo. Ha resin ea polyimide le resin ea polysulfone li etsoa lifilimi 'me lifilimi tsa resin ea polyether ketone li otlolloa, kalafo ka DMI e ka etsa hore lifilimi li tšoane haholoanyane.

6. Sesebelisoa sa ho hlobola mokhoa oa ho nka linepe

Ka lebaka la ho ba le viscosity e tlase le ho se fetohe ha dielectric e phahameng, DMI e ka sebediswa e le solvent ya electrolyte bakeng sa dibetri tsa lithium tse sebetsang hantle. Ho feta moo, e na le ho kenella ho matla, ntlha e phahameng ya ho belisa le ho hanyetsa mocheso o phahameng, mme e ka sebediswa hape e le stripper bakeng sa silicon wafer photoresist. Thepa ya yona ya ho hlobola ka potlako le e sa senyeheng e nolofatsa haholo tshebetso ya ho hlobola le ho potlakisa tlhahiso ya ho seha di-chip.

7. Sesepa sa ho hlatsoa

DMI e eketsoa motswakong wa di-surfactants, di-alkali, di-alcohol le di-polyoxyethylene alkyl ethers ho fumana sesepa se matla. Kaha DMI e bonolo haholo ho qhibilihisa ditshila, e ka boela ya sebediswa ho lokisa ditharollo tse sebetsang hantle tsa ho hlwekisa bakeng sa ho hlwekisa khalase le tshepe.

8. Lidae le mebala

Enke e entsoeng ka ho kopanya DMI le likarolo tsa solvent le dae le mebala e ka hatisoa ka tsela e fapaneng, 'me setšoantšo se hlakile.

9. Moemeli oa kalafo ea bokaholimo

DMI e ka sebelisoa e le sesebelisoa sa kalafo ea bokaholimo ho ntlafatsa matla a ho kopanya a ABS, polyimide, PPS, Teflon le lisebelisoa tse ling ka likhomaretsi tsa resin ea epoxy.
