Acetonitrile: Solvent e Sebetsang le Reagent bakeng sa ho Kopanya Lintho tsa Tlhaho
Masimo a Maholo a Kopo
Tlhahlobong ea lik'hemik'hale, acetonitrile ke tharollo e sebelisoang haholo bakeng sa tlhahlobo ea chromatography ea metsi e sebetsang hantle (HPLC) le chromatography ea khase (GC). E na le ho qhibiliha ho hotle le viscosity e tlase, e qhalanya metsoako e fapaneng ea lintho tse phelang le tse sa pheleng hantle ho fana ka liphetho tse hlakileng tsa tlhahlobo. Acetonitrile e boetse e sebelisoa ho lokisa litharollo tse tloaelehileng le maro a ho lekanya, ho netefatsa ho nepahala le ho tšepahala ha tlhahlobo.
Ka ho kopanya lintho tse phelang, acetonitrile ke tharollo ea bohlokoa le e mahareng. E ka qhala mefuta e fapaneng ea metsoako ea tlhaho, e fana ka tikoloho e tsitsitseng bakeng sa liketso tsa lik'hemik'hale. Mohlala, ka ho kopanya metsoako e itseng ea meriana le metsoako ea monko, acetonitrile e ka sebetsa e le tharollo ho khothaletsa karabelo. Ho feta moo, acetonitrile e ka nka karolo liketsong tse itseng tsa lik'hemik'hale ho hlahisa metsoako e nang le mesebetsi e itseng. Mohlala, acetonitrile e ka feta liketsong tsa nukleophilic substitution le sehlopha sa eona sa cyano ho hlahisa metsoako e tsamaellanang ea amine kapa joala.
Indastering ea meriana, acetonitrile e sebelisoa haholo lits'ebetsong tsa ho kopanya le ho hloekisa lithethefatsi. E ka qhala mefuta e fapaneng ea lintho tse etellang pele lithethefatsi le tse mahareng, e leng se thusang ho etsa hore lik'hemik'hale li sebetse hantle. Mohlala, tlhahisong ea lithibela-mafu tse itseng le meriana ea pelo le methapo ea mali, acetonitrile e ka sebetsa e le tharollo ho eketsa sekhahla sa karabelo le chai. Ho feta moo, acetonitrile e ka sebelisoa bakeng sa ho etsa hore lithethefatsi li kristale le ho hloekisoa ho netefatsa bohloeki le boleng ba lithethefatsi.
Indastering ea monko o monate le litlolo, acetonitrile e sebelisoa bakeng sa ho kopanya le ho hloekisa metsoako ea monko o monate. E ka sebelisoa ho ntša likarolo tsa monko oa tlhaho, joalo ka oli ea bohlokoa ho tsoa limela. Ho feta moo, acetonitrile e ka sebelisoa ho kopanya metsoako ea monko o monate ka monko o ikhethang bakeng sa litlolo tse nkhang hamonate le litlolo.
Indastering ea lisebelisoa tsa elektroniki, acetonitrile e sebelisoa e le sesebelisoa sa ho hloekisa le ho qhibilihisa. E ka tlosa masalla le litšila ka katleho holim'a likarolo tsa elektroniki, e netefatsa bohloeki le ts'ebetso ea likarolo tsa elektroniki. Mohlala, tlhahisong ea semiconductor, acetonitrile e ka sebelisoa ho hloekisa bokaholimo ba li-wafer, ho tlosa masalla a photoresist le litšila tse ling.
Ho sa tsotellehe mefuta e mengata ea ts'ebeliso ea eona, acetonitrile e fetoha habonolo ebile e na le chefo, 'me tšebeliso le polokelo ea eona e hloka mehato e tiileng ea ts'ireletso. Acetonitrile e fetoha mouoane habonolo moeeng, kahoo e lokela ho sebelisoa tikolohong e nang le moea o kenang hantle. Ho feta moo, litharollo tsa acetonitrile li na le chefo e itseng, 'me lisebelisoa tse loketseng tsa tšireletso li lokela ho aparoa nakong ea ts'ebeliso ho qoba ho kopana le letlalo le mahlo. Tlhahisong ea indasteri, ts'ebeliso ea acetonitrile hangata e etsahala lits'ebetsong tse koetsoeng ho fokotsa tšusumetso ea tikoloho.
