Iphuzu elibilayo le-cyclohexane: ukuhlaziywa okujulile kanye nokusetshenziswa
I-Cyclohexane iyinhlanganisela ebalulekile esetshenziswa kabanzi embonini yamakhemikhali futhi izakhiwo zayo ezibonakalayo zinomthelela omkhulu ekukhiqizweni kwezimboni. Phakathi kwazo, indawo yokubilisa ye-cyclohexane iyipharamitha ebalulekile, ebaluleke kakhulu ekwakhiweni nasekusebenziseni izinqubo eziningi. Kuleli phepha, indawo yokubilisa ye-cyclohexane izohlaziywa ngokuningiliziwe, futhi ubudlelwano bayo nezinye izici kanye nokubaluleka kwayo ekusetshenzisweni okungokoqobo kuzoxoxwa ngayo.
Ulwazi oluyisisekelo endaweni yokubilisa ye-cyclohexane
I-Cyclohexane iyi-saturated cyclic hydrocarbon ene-chemical formula C6H12. Iphuzu layo elibilayo ekucindezelweni komkhathi ngu-80.74°C. Lokhu kushisa okuphansi kakhulu kwenza kube lula ukulawula ukuguquka kwesigaba phakathi kwezimo eziwuketshezi negesi ze-cyclohexane. Lesi sakhiwo sibaluleke kakhulu ekukhiqizweni kwamakhemikhali, ikakhulukazi uma izinqubo ezifana nokukhishwa kwe-distillation nokuhlukaniswa kuhilelekile. Ukuqonda indawo yokubilisa ye-cyclohexane kungasiza ekwakheni kangcono okokusebenza nezimo zokusebenza ezinqubweni ezihlobene.
Ubudlelwano phakathi kwendawo yokubilisa kanye nesakhiwo samangqamuzana e-cyclohexane
Iphuzu elibilayo le-cyclohexane lithinteka kakhulu ukwakheka kwamangqamuzana. I-molecule ye-Cyclohexane iqukethe ama-athomu e-carbon ayisithupha nama-athomu e-hydrogen ayishumi nambili, ebonisa ukwakheka kwendandatho ene-hexagonal ezinzile. Ngenxa yokuthi kukhona amandla e-van der Waals kuphela phakathi kwama-molecule, i-cyclohexane inephuzu lokubila eliphansi kunama-molecule amaningi asezindaweni ezishisayo. Uma kuqhathaniswa nezinhlanganisela zayo ezifanayo ngokwesakhiwo, imvelo ye-cyclohexane engapholi iphumela endaweni yokubilisa ephansi kunezisindo ezifanayo zamaketanga aqondile. Ngakho-ke, iphuzu lokubilisa le-cyclohexane liba yisici okufanele sicatshangelwe lapho kukhethwa i-solvent noma ukusetha izimo zokusabela.
Ukubaluleka kwendawo yokubilisa ye-cyclohexane ezisetshenziswa zezimboni
Iphuzu elibilayo le-cyclohexane lidlala indima ebalulekile ezinhlobonhlobo zezinqubo zamakhemikhali. Isibonelo, ezinqubweni ze-petrochemical hydro-refining, i-cyclohexane ivame ukusetshenziswa njenge-solvent noma i-intermediate, futhi ulwazi lwephoyinti layo lokubilisa lungasiza ekwandiseni izinga lokushisa lokuphendula nezimo zengcindezi. Ku-high performance liquid chromatography (HPLC), i-cyclohexane ivame ukusetshenziswa njengengxenye yesigaba esihambayo ngenxa yephuzu layo eliphansi lokubilisa kanye nokuncibilika okuhle, okuqinisekisa ukuthi isincibilikisi siyahwamuka ngokushesha ngaphandle kokuphazamisa inqubo yokuhlukanisa.
Ukucatshangelwa Kwemvelo Nokuphepha Kwephoyinti Elibilisayo le-Cyclohexane
Empeleni, ulwazi lwephuzu lokubilisa le-cyclohexane nalo lubalulekile ekukhiqizeni okuphephile. Ngenxa yephuzu eliphansi lokubilisa nokuntengantenga, ikakhulukazi emazingeni okushisa aphezulu, i-cyclohexane idinga ukunakwa okukhethekile ukuze ilawule ukugcwala kwayo komhwamuko ukuze igweme ukuqhuma noma imililo. Isistimu yokungenisa umoya ekahle kufanele ifakwe esitshalweni ngemishini efanele yokuthola ukuze kuqinisekiswe ukuthi umhwamuko we-cyclohexane aweqeli umkhawulo wokuphepha.
Isifinyezo
Iphuzu lokubilisa le-cyclohexane liwuhlaka olubalulekile olungenakunakwa ekukhiqizeni amakhemikhali kanye nemisebenzi yokuhlola. Ukuqonda okuningiliziwe kwephoyinti layo lokubilisa kunika amandla idizayini yenqubo engcono kanye nokwenza kahle, futhi kusiza nokuqinisekisa ukuphepha enqubweni yokukhiqiza. Ekusetshenzisweni kwamakhemikhali esikhathini esizayo, ngokuqhubeka okuqhubekayo kobuchwepheshe, ucwaningo nokuqonda indawo yokubilisa ye-cyclohexane kuzoba ukujula, kukhuthaze izinqubo zokukhiqiza amakhemikhali ezisebenza kahle neziphephile.
