DMF ke mofuta ofe oa solvent?
Dimethylformamide (DMF) ke solvent e sebelisoang haholo indastering ea lik'hemik'hale. Ho utloisisa hore na DMF ea solvent ke ea mofuta ofe ho bohlokoa ho litsebi tsa tlhahiso ea lik'hemik'hale, lipatlisiso tsa laboratori le likarolo tse amanang le tsona. Sehloohong sena, re tla sekaseka ka ho qaqileng litšobotsi tsa lik'hemik'hale tsa DMF, ts'ebeliso ea eona le ts'ebeliso ea eona mafapheng a fapaneng ho thusa babali ho fumana kutloisiso e felletseng ea solvent ena ea bohlokoa.
Khemistri ea DMF
DMF ke mofuta ofe oa solvent? Pele ho tsohle, re lokela ho qala ka thepa ea eona ea lik'hemik'hale.Mokhoa oa molek'hule oa lik'hemik'hale oa DMF ke C₃H₇NO, 'me ka sebopeho ke dimethyl substituent of formamide. Ke mokelikeli o se nang 'mala, o bonaletsang, o phallang habonolo o nang le monko o fokolang oa tlhapi.Ntho e ikhethang ea DMF ke polarity ea eona e phahameng haholo, e nang le dielectric constant ho fihla ho 36.7, le matla a phahameng a solvency, e leng se nolofalletsang ho qhaqha lintho tse polar le tse seng polar. Ka hona, DMF e bapala karolo ea bohlokoa e le solvent mefuteng e fapaneng ea lik'hemik'hale.
Mefuta e fapaneng ea DMF
Ho utloisisa hore na DMF ke eng e le mokelikeli ho thusa ho lemoha mefuta e mengata ea tšebeliso ea eona libakeng tse fapaneng.DMF e sebelisoa haholo-holo e le polymer dissolver, chemical reaction medium le ho hloekisa solvent. Ka mohlala, tlhahisong ea likhoele le polasetiki, DMF ke motsoako o babatsehang oa polyurethane le polyvinyl chloride; indastering ea meriana, e sebelisoa haholo e le mokhoa oa ho arabela bakeng sa motsoako oa manyolo, haholo-holo bakeng sa ho lokisa lintho tse sebetsang. Lilaboratoring tsa lik'hemik'hale, hangata DMF e sebelisoa ho qhaqha mefuta e fapaneng ea metsoako ea polar, ho thusa bafuputsi ho etsa ts'ebetso e nepahetseng ea lik'hemik'hale.
Melemo ea DMF lits'ebetsong tse khethehileng
Lits'ebetsong tse ling tse khethehileng, karolo ea DMF e hlahella haholoanyane. Ka mohlala, DMF e sebelisoa haholo ho electrochemistry, moo boemo ba eona bo phahameng ka ho fetisisa ba dielectric bo etsang hore e be motsoako o tloaelehileng litekong tsa electrochemical, 'me ke motsoako oa bohlokoa oa ho hloekisa, haholo-holo bakeng sa lits'ebetso tsa ho hloekisa tse hlokang li-solvents tse ngata haholo, tse kang ho hloekisa lisebelisoa tsa elektronike le lisebelisoa tse nepahetseng. Ho utloisisa hore na DMF ke solvent ho ka thusa ho khetha mokhoa o nepahetseng oa ho hloekisa le ho ntlafatsa katleho ea mosebetsi.
Tšireletseho le Matšoenyeho a Tikoloho a DMF
Le hoja DMF e na le mefuta e mengata ea likopo, empa tšireletso ea eona le tšireletso ea tikoloho ha ea lokela ho hlokomolohuoa. DMF e na le tekanyo e itseng ea chefo, ho pepeseha ha nako e telele ho ka baka tšenyo ho sebete, tšebeliso ea ts'ebetso e lokela ho nka mehato e nepahetseng ea tšireletso, joalo ka ho roala liatlana tse sireletsang, limaske, ho netefatsa hore tikoloho ea ts'ebetso e na le moea o motle. Ho lahloa ha litšila tsa DMF le hona ke taba ea bohlokoa, taolo e utloahalang ea litšila ke senotlolo sa ho fokotsa tšilafalo ea tikoloho.
Qetello
DMF ke solvent ea bohlokoa haholo ebile e sebelisoa haholo. Ho utloisisa hore na DMF ke solvent ho ke ke ha thusa feela litsebi ho khetha hantle le ho sebelisa solvent, empa hape ho ntlafatsa polokeho le katleho ts'ebetsong ea sebele. Ka nts'etsopele e tsoelang pele ea theknoloji ea lik'hemik'hale, tlhoko le ts'ebeliso ea DMF le tsona li tla hola.
