Iphuzu elibilayo le-n-hexane: ukuhlaziywa okuningiliziwe kanye nengxoxo yohlelo lokusebenza
I-Hexane iyi-solvent evamile embonini yamakhemikhali, futhi izakhiwo zayo ezibonakalayo, njengendawo yokubilisa, zinomthelela oqondile ekutheni isetshenziswa kuphi futhi kanjani. Ngakho-ke, ukuqonda okujulile kwendawo yokubilisa ye-n-hexane kanye nezakhiwo zayo ezihlobene kubaluleke kakhulu kochwepheshe embonini yamakhemikhali. Kulesi sihloko, sizoxoxa ngesihloko sephuzu elibilisayo le-n-hexane ngokuningiliziwe futhi sihlaziye izici zayo zamaphuzu abilayo, izici ezithonya kanye nokusetshenziswa okusebenzayo.
Uhlolojikelele lwephoyinti lokubilisa le-hexane
I-Hexane inephuzu lokubila elingu-68.7°C (cishe u-342 K). Leli phuzu lokushisa lilenza liziphathe njengoketshezi olungenambala, olune-viscosity ephansi ekamelweni lokushisa nokucindezela. Izici zamaphuzu aphansi abilayo e-hexane ziwenza isinyibilikisi esifanele ukusetshenziswa embonini, ikakhulukazi ezinqubweni ezidinga ukuhwamuka okusheshayo, njengokukhishwa kwamafutha, okokuhlanza kanye nama-coatings.
Izinto ezithinta indawo yokubilisa ye-hexane
Nakuba i-hexane inephuzu lokubilisa elijwayelekile elingu-68.7°C, iphoyinti layo langempela lokubilisa lingahluka kuye ngezinto ezimbalwa. Ukucindezela komkhathi kuyisici esibalulekile esinomthelela. Ezindaweni eziphakeme noma izingcindezi eziphansi, indawo yokubilisa ye-hexane izoba ngaphansi kuka-68.7°C, okusho ukuthi izohwamuka ngokushesha. Ngokuphambene, ngaphansi kwezimo zokucindezela okukhulu, iphuzu layo elibilisayo lizokhuphuka kancane.
Ukuhlanzeka kwe-hexane nakho kuthinta indawo yayo yokubilisa. Uma i-hexane iqukethe ukungcola, njengamanye ama-alkanes, iphoyinti layo lokubilisa lingashintsha. Ngokuvamile, ukuba khona kokungcola kubangela ukwanda kwendawo yokubilisa noma kukhiqiza uhla lwamaphuzu abilayo kunevelu eyodwa yokubilisa.
Izicelo Ze-Hexane Boiling Points Embonini
Iphuzu eliphansi lokubilisa le-hexane liyenza ibaluleke ezinhlelweni eziningana zezimboni. Isibonelo, embonini yokukhipha amafutha namafutha, i-hexane ivame ukusetshenziselwa ukukhipha amafutha namafutha embewu yezitshalo. Iphuzu layo eliphansi lokubilisa liqinisekisa ukuthi i-solvent iyahwamuka ngokushesha ekupheleni kwenqubo yokukhipha futhi ayishiyi izinsalela eziningi emkhiqizweni wokugcina, ngaleyo ndlela ithuthukise ubumsulwa nekhwalithi yayo.
I-Hexane nayo isetshenziswa kabanzi ekuhlanzeni nasekususeni amafutha. Kulezi zinhlelo zokusebenza, iphoyinti eliphansi lokubilisa le-hexane liyivumela ukuthi ihwamuke ngokushesha, iqinisekise ukomiswa ngokushesha ngemva kokuhlanza okokusebenza nezindawo, kuyilapho kunciphisa umthelela woketshezi oluyinsalela ezinqubweni ezilandelayo.
Isiphetho
Iphuzu elibilayo le-n-hexane lingaphezu kokungaguquguquki komzimba okulula; inohlu olubanzi lokubaluleka okusebenzayo ekusetshenzisweni kwezimboni. Ukuqonda indawo yokubilisa ye-n-hexane nezici eziyithonya kungasiza ochwepheshe bemboni yamakhemikhali ukuthi bakhethe kangcono futhi basebenzise lesi sincibilikisi ukuthuthukisa ukukhiqiza nokuqinisekisa ikhwalithi yomkhiqizo. Izici zamaphuzu abilayo ze-n-hexane zidlala indima engenakuthathelwa indawo ezimeni ezihlukene zezimboni. Ngakho-ke, ucwaningo olujulile nokuqonda iphuzu lokubilisa le-n-hexane kubalulekile ukuze kuthuthukiswe inqubo.
