Iphuzu elibilayo le-acetonitritria: Ukuhlaziywa kwezindawo ezibalulekile zomzimba kanye nezicelo zezimboni
I-Acetonitrile iyindawo evamile ye-organic ephathekayo ngefomula yamakhemikhali ch₃cn.as i-solvent ye-polar, i-acetonitrile isetshenziswa kabanzi kwizimboni zamakhemikhali, ezemithi kanye nezimboni zamakhemikhali. Ukuqonda izakhiwo ezibonakalayo ze-acetonitrile, ikakhulukazi iphuzu elibilayo le-acetonitritrile, libaluleke kakhulu isicelo salo. Kuleli phepha, iphuzu elibilayo le-acetonitrile nokubaluleka kwalo embonini kuzoxoxwa ngakho ngokujulile.
Izakhiwo eziyisisekelo nephuzu elibilayo le-acetonitrile
I-Acetonitrile iwuketshezi olungenamibala futhi olusobala olune-polarity ephezulu, ngakho-ke ingahlakaza amakhompiyutha amaningi we-polar ne-non-polar. I-Acetonitrile inendawo ebilayo engu-81.6 ° C, izinga lokushisa elibalulekile ekusebenzeni kwamakhemikhali. Iphoyinti eliphansi lika-Acetonitrile libilayo lenza kube lula ukuhwamuka ekushiseni kwegumbi kanye nengcindezi, okwenza kube lula izinqubo eziningi ezidinga ukomisa noma ukuguquguquka okusheshayo.
Ukubaluleka kwe-Acetonitritrile Boiling Point ku-Solvent Application
I-Acetonitrile isetshenziswa kabanzi njenge-solvent ekuhlaziyweni kwe-chromatographic okufana nokusebenza okuphezulu kwe-chromatography (HPLC). Ku-HPLC, iphuzu elibilayo le-solvent lithinta ukukhetha kwesigaba seselula kanye nomphumela wokuhlukanisa. Ngenxa yendawo ebilayo ephansi ye-acetonitritrile, ingahwalala ngokushesha, ukunciphisa izinsalela nokwenza ngcono ubumsulwa besampula. Ukusetshenziswa kwe-acetonitrile ku-synthesis yamakhemikhali nakho kuncike kwizici zayo ezibilayo. Isibonelo, kokunye okwenziwe ngezinto ezenziwa lapho izinga lokushisa vele lizolawulwa, iphuzu elibilayo le-acetonitritle lingasetshenziswa njengesethenjwa sokulungisa izimo zokuphendula.
Ukulawulwa kwephuzu elibilayo le-acetonitritria ekukhiqizeni kwezimboni
Ekukhiqizweni nasekugcinweni kwe-acetonitritria, ukulawulwa kwephuzu elibilayo le-acetonitritrile kubalulekile. Njengoba i-acetonitrile inokuqina okuphezulu, kudingeka ukulawulwa kokushisa okuqinile ngesikhathi sokukhiqiza ukuvikela ukuhwamuka kwayo ngokweqile, okungathinta isivuno nekhwalithi. Lapho ugcina i-acetonitrile, kuvame ukudingeka ukuba ube sezingeni eliphansi lokushisa noma indawo evaliwe ukuze unciphise ukulahleka okuguquguqukayo kwe-acetonitritrile futhi uqinisekise ukuphepha.
Ukuphepha kanye nokucatshangelwa kwemvelo kwendawo ebilayo ye-acetonitritrile
Ukuguquguquka kwe-acetonitritria kwenza ukuthi ukubila kwayo kufinyelele isici esibalulekile ekuphepheni nasekucabangeni kwemvelo. Lapho usingatha futhi usebenzisa i-acetonitritria, ukuguquguquka kwawo kumele kubhekwe ukuvikela ukuphefumula okugxile kakhulu kwe-acetonitrile vapor. Ulwazi lwephuzu elibilayo le-acetonitritrile kungasiza ukuthuthukisa amasu asebenzayo asebenzayo (VOC) amasu okulawulwa kokuphuma ukunciphisa imithelela yemvelo ngesikhathi sokwelashwa kwemfucuza yezimboni.
Ukubeka kafushane
Ulwazi lwephuzu elibilayo le-acetonitritria lubalulekile kwisicelo salo sezimboni. Noma ngabe kuyinqubo yokukhiqiza, ukugcinwa noma ukusetshenziswa, iphuzu elibilayo le-acetonitritrile lithinta ngqo ukuphepha, ukusebenza kahle kanye nokuvikelwa kwemvelo kokusebenza. Ngakho-ke, embonini yamakhemikhali, enaka iphuzu elibilayo le-acetonitritria kungenye yezikhiye zokuqinisekisa ukusebenza kahle kwezinqubo.
