Iphuzu elibilisayo le-acetonitrile: ipharamitha ebalulekile yomzimba embonini yamakhemikhali
I-Acetonitrile, njengesixazululi esibalulekile se-organic embonini yamakhemikhali, isetshenziswa kabanzi emkhakheni wokuhlanganiswa kwezidakamizwa, amakhemikhali amahle kanye nokuhlaziywa kwe-chromatography ewuketshezi. Ukwazi kahle amapharamitha aphathekayo we-Acetonitrile kubalulekile ekusebenzeni kwayo embonini, phakathi kwayo indawo yokubilisa ingenye yemingcele ebaluleke kakhulu. Kuleli phepha, indawo yokubilisa ye-acetonitrile izohlaziywa ngokuningiliziwe, futhi umthelela wale parameter ekusebenzeni kwamakhemikhali kuzoxoxwa ngakho.
Iphuzu elibilayo le-acetonitrile kanye nezici zayo ezinomthelela
Iphuzu elibilayo le-acetonitrile livamise ukuba ngu-81.6°C (cishe u-179°F), futhi lelizinga lokushisa libaluleke kakhulu ekukhipheni izinti, ukulungisa kanye nezinye izindlela zokuhlukanisa ezinqubweni zamakhemikhali. Iphuzu lokubilisa le-acetonitrile lithintwa izici eziningi, okuhlanganisa ukucindezela, ukuhlanzeka, nokuxuba nezinye izinto. Ngokuvamile, iphuzu lokubilisa le-acetonitrile lilinganiselwe ngaphansi kokucindezela okujwayelekile komkhathi, kodwa uma ingcindezi ishintsha, iphuzu lokubilisa lizoshintsha. Isibonelo, ngaphansi kwengcindezi encishisiwe, indawo yokubilisa ye-acetonitrile iyancipha, futhi ngokuphambene, ngaphansi kwezimo ezicindezelayo, iphuzu lokubilisa liyakhula. Lesi sici senza i-acetonitrile ibe nokwenzeka okubanzi kwesicelo ngaphansi kwezimo zenqubo ehlukene.
Ukubaluleka kwephuzu lokubilisa le-acetonitrile ekusetshenzisweni kwezimboni
Ukwazi indawo yokubilisa ye-acetonitrile kuyinkomba ebalulekile yokwenza izimo zokusebenza kwamakhemikhali. Emkhiqizweni wezimboni, kuvame ukudingekile ukuhlukanisa izingxube, futhi iphuzu lokubilisa le-acetonitrile lenza kube enye yezinto ezinhle kakhulu ohlelweni lokubuyisela i-solvent. Isibonelo, ekuhlaziyweni kwe-chromatography ewuketshezi, indawo yokubilisa efanelekile ye-acetonitrile iyenza ihwamuke ngezinga lokushisa eliphansi uma kuqhathaniswa, kugwenywe ngempumelelo ukuwohloka kokushisa kwesampula. Kumakhemikhali okwenziwa, ukulawula izinga lokushisa lokusabela eduze noma ngaphansi kwendawo yokubilisa ye-acetonitrile kusiza ukuqinisekisa ukuphepha kokusabela kanye nobumsulwa bemikhiqizo.
Isetshenziswa kanjani indawo yokubilisa ye-acetonitrile ukuze uthuthukise inqubo yokukhiqiza
Ngokwazi nokuqonda indawo yokubilisa ye-acetonitrile, onjiniyela bangathuthukisa izinqubo zokukhiqiza ukuze bathuthukise ukusebenza kahle nokunciphisa izindleko. Isibonelo, enqubweni ye-distillation, indawo yokubilisa ye-acetonitrile ingasetshenziswa njengesisekelo esibalulekile sokusetha izinga lokushisa lokusebenza kwekholomu ye-distillation ukuze kuqinisekiswe ukusebenza kahle kokuhlukanisa. Ngokulungisa ingcindezi yesistimu ukuze ushintshe indawo yokubilisa ye-acetonitrile, kungenzeka ukufeza imisebenzi yokukhiqiza eguquguqukayo ngaphansi kwezimo zezinqubo ezahlukene. Le ndlela ayikwazi nje ukugcina amandla ngokuphumelelayo, kodwa futhi ithuthukise ukuphepha nokuzinza kwawo wonke umugqa wokukhiqiza.
Isifinyezo
Iphuzu elibilayo le-acetonitrile liwuhlaka olubalulekile lomzimba embonini yamakhemikhali, oluthinta ngokuqondile ukwakhiwa nokuqaliswa kokusebenza kwamakhemikhali okuhlukahlukene. Kusukela ezicini eziyisisekelo ze-acetonitrile, ukuqonda okujulile kwezinto ezinomthelela endaweni yokubilisa kanye nendima yayo ezinhlelweni zemboni kungasiza onjiniyela bathuthukise kangcono inqubo yokukhiqiza, bathuthukise ikhwalithi yomkhiqizo futhi bafinyelele umgomo wentuthuko esimeme. Ngokuqonda ngokugcwele nokusebenzisa iphuzu lokubilisa le-acetonitrile, izinkampani zamakhemikhali ziyakwazi ukusizakala ngokuncintisana kwemakethe okushubile.
