Iphuzu elibilayo le-acetonitrile: ipharamitha ebalulekile yomzimba embonini yamakhemikhali
I-Acetonitrile, njenge-solvent ebalulekile ye-organic embonini yamakhemikhali, isetshenziswa kabanzi emikhakheni yokuhlelwa kwezidakamizwa, amakhemikhali amahle kanye nokuhlaziywa kwe-chromatography ewuketshezi. Ukukwazi kahle amapharamitha angokomzimba we-acetonitritritrisrile kubalulekile ukuthola uhlelo lokusebenza lwayo embonini, phakathi kwalona i-Boiling Point kungenye yamapharamitha abucayi kakhulu. Kuleli phepha, iphuzu elibilayo le-acetonitritle lizohlaziywa ngokuningiliziwe, futhi ithonya lale pharamitha ekusebenzeni kwamakhemikhali kuzoxoxwa ngalo.
Iphuzu elibilayo le-acetonitritria kanye nezinto zalo ezithonyelayo
Iphoyinti elibilayo le-acetonitritria livame ukuba ngu-81.6 ° C (cishe ngo-179 ° F), futhi lokhu kushisa kubaluleke kakhulu ekuhlolweni, ukulungiswa kabusha kanye namanye amasu okuhlukanisa ngezinqubo zamakhemikhali. Iphoyinti elibilayo le-acetonitrifria lithintwa yizici eziningi, kufaka phakathi ingcindezi, ubumsulwa, kanye nokuxuba nezinye izinto. Imvamisa, iphuzu elibilayo le-acetonitrile lihleliwe ngaphansi kwengcindezi ejwayelekile yomoya, kepha uma ingcindezi ishintsha, iphuzu elibilayo lizoshintsha. Isibonelo, ngaphansi kwengcindezi encishisiwe, iphuzu elibilayo le-acetonitritle liyancipha, futhi ngakolunye uhlangothi, ngaphansi kwezimo ezicindezelwe, iphuzu elibilayo liyanda. Lesi simo senza i-acetonitrile ine-application ebanzi yokusebenzisa ngaphansi kwezimo zenqubo ezahlukahlukene.
Ukubaluleka kwephuzu elibilayo le-acetonitritre ezisetshenzisweni zezimboni
Ukwazi iphuzu elibilayo le-acetonitritrile yinani elibalulekile lereferensi yokwakha izimo ezingekho emthethweni zamakhemikhali. Ekukhiqizeni kwezimboni, kuvame ukudingekile ukuhlukanisa izingxube, futhi iphuzu elibilayo le-acetonitrile lenza kube ngenye yezinto ezinhle kakhulu kwinqubo yokuvuselela i-solvent. Isibonelo, ekuhlaziyweni kwe-chromatography ye-chromatography, indawo efanelekile ye-acetonitritrile ikwenza ukwazi ukuguquguquka ekushiseni okuphansi, ngokuphumelelayo ukugwema ukonakala kwesampula. Ku-sonthetic chemistry, elawula izinga lokushisa lokuphendula eliseduze noma ngaphansi kwephuzu elibilayo le-acetonitrifre lisiza ukuqinisekisa ukuphepha kokuphendula kanye nobumsulwa bemikhiqizo.
Ungayisebenzisa kanjani iphuzu elibilayo le-acetonitritrale ukwenza kahle inqubo yokukhiqiza
Ngokwazi nokuqonda iphuzu elibilayo le-acetonitritria, onjiniyela bangabe ngcono nezinqubo zokukhiqiza ukuze bathuthukise ukusebenza kahle futhi banciphise izindleko. Isibonelo, kwinqubo yokuhlobisa, iphuzu elibilayo le-acetonitritrelitile lingasetshenziswa njengesisekelo esibalulekile sokubeka izinga lokushisa elisebenzayo lekholomu ye-distillation ukuqinisekisa ukusebenza kahle kwe-distillation ukuqinisekisa ukusebenza kahle kwe-distillation ukuqinisekisa ukusebenza kahle kokuhlukanisa. Ngokushintsha ingcindezi yesistimu yokushintsha iphuzu elibilayo le-acetonitritrile, kungenzeka ukufeza imisebenzi eguquguqukayo yokukhiqiza ngaphansi kwezimo zenqubo ezihlukile. Le ndlela ayikwazi ukonga amandla kuphela ngempumelelo, kepha futhi ithuthukise ukuphepha nokuqina komugqa wonke wokukhiqiza.
Ukubeka kafushane
Iphoyinti elibilayo le-acetonitritria liyipharamitha ebalulekile emzimbeni embonini yamakhemikhali, ethinta ngqo ukwakhiwa kanye nokuqaliswa kokusebenza okuhlukahlukene kwamakhemikhali. Kusukela kwizakhiwo eziyisisekelo ze-acetonitritria, ukuqonda okujulile kwezinto ezithonya kwephuzu lazo elibilayo neqhaza lazo ezinhlandlela zezimboni kungasiza onjiniyela kangcono inqubo yokukhiqiza, bathuthukise ikhwalithi yomkhiqizo futhi bazuze inhloso yentuthuko esimeme. Ngokuqonda ngokuphelele nokusebenzisa iphuzu elibilayo le-acetonitritrale, izinkampani zamakhemikhali ziyakwazi ukusizakala ngomncintiswano wemakethe onolaka.
