I-Isopropanol Boiling Point: Ukuhlaziywa Okuningiliziwe kanye Nezicelo
I-Isopropanol, eyaziwa nangokuthi i-isopropyl alcohol noma i-2-propanol, iyi-solvent evamile esetshenziswa kabanzi kumakhemikhali, imithi kanye nokuphila kwansuku zonke. Iphuzu lokubilisa liyipharamitha ebaluleke kakhulu lapho kuxoxwa ngezakhiwo ze-Isopropanol. Ukuqonda ukubaluleka kwephuzu lokubilisa le-isopropanol akusizi nje kuphela ekwandiseni ukusetshenziswa kwayo kwezimboni kodwa nasekuvikelekeni kokusebenza elabhorethri.
Izakhiwo Eziyisisekelo kanye Nesakhiwo Se-Isopropyl Alcohol
I-Isopropyl alcohol ine-molecular formula C₃H₈O futhi ingeyeqembu lotshwala. Esakhiweni salo samangqamuzana, iqembu le-hydroxyl (-OH) linamathele ku-athomu ye-carbon yesibili, futhi lesi sakhiwo sinquma izakhiwo zomzimba namakhemikhali ze-isopropanol. Njengento encibilikayo ephakathi nendawo emaphakathi, i-isopropyl alcohol ixubana namanzi nezincibilikisi eziningi eziphilayo, okuyenza ibe yinhle kakhulu ekuhlakazeni nasekuhlambululeni inhlobonhlobo yamakhemikhali.
Ukubaluleka Okungokomzimba Kwe-Isopropyl Alcohol Boiling Point
I-Isopropyl alcohol inephuzu lokubilisa elingu-82.6°C (179°F), likalwa ngomfutho ojwayelekile womkhathi (1 atm). Leli phuzu elibilayo liwumphumela wamandla okuhlanganiswa kwe-hydrogen phakathi kwama-molecule e-isopropyl alcohol. Nakuba i-isopropanol inesisindo esincane samangqamuzana, ukuba khona kwamaqembu e-hydroxyl ku-molecule kwenza ukwakheka kwezibopho ze-hydrogen phakathi kwama-molecule, futhi lokhu kuhlanganiswa kwe-hydrogen kuthuthukisa ukukhanga kwe-intermolecular, ngaleyo ndlela kwandisa iphuzu lokubilisa.
Uma kuqhathaniswa nezinye izinhlanganisela zesakhiwo esifanayo, njenge-n-propanol (iphuzu lokubilisa lika-97.2 ° C), i-isopropanol inephuzu lokubilisa eliphansi. Lokhu kungenxa yokuma kweqembu le-hydroxyl ku-molecule ye-isopropanol okuholela ekuhlanganiseni okubuthakathaka kwe-intermolecular hydrogen, okwenza kube nokuguquguquka okwengeziwe.
Umthelela we-Isopropyl Alcohol Boiling Point ku-Industrial Application
Inani eliphansi uma kuqhathaniswa lephuzu lokubilisa le-isopropyl alcohol lenza liphumelele ekucwilisweni kwezimboni nasekulungiseni. Ngenxa yephuzu layo eliphansi lokubilisa, lapho kwenziwa ukuhlukaniswa kwe-distillation, i-isopropanol ingahlukaniswa ngokuphumelelayo emazingeni okushisa aphansi, konga ukusetshenziswa kwamandla. I-Isopropanol iyaguquguquka emazingeni okushisa aphansi, okwenza ukuthi isetshenziswe kabanzi ekugqokeni, ekuhlanzeni ama-agent kanye nama-disinfectants. Kulezi zinhlelo zokusebenza, izakhiwo zokuhwamuka okusheshayo ze-isopropyl alcohol zisusa kahle amanzi angaphezulu namafutha ngaphandle kwezinsalela.
Ukucatshangelwa Kwamaphuzu Okubilisa we-Isopropyl Alcohol ekusebenzeni kweLabhorethri
Iphuzu elibilayo le-isopropyl alcohol nalo liyisici esibalulekile elabhorethri. Isibonelo, lapho wenza ukusabela kokushisa noma ukubuyiswa kwe-solvent, ukwazi indawo yokubilisa ye-isopropyl alcohol kungasiza ososayensi bakhethe izimo ezifanele ukuze bagweme ukushisa ngokweqile kanye nokuhwamuka kwe-solvent ngokweqile. Iphuzu eliphansi lokubilisa liphinde lisho ukuthi i-isopropanol idinga ukugcinwa futhi isetshenziswe ngokucophelela ukuze kuvinjelwe ukulahlekelwa okuguquguqukayo futhi isetshenziswe endaweni enomoya omuhle ukuze kuqinisekiswe ukuphepha.
Isiphetho
Ukuqonda indawo yokubilisa ye-isopropanol kubalulekile ekusetshenzisweni kwayo embonini nasemalabhorethri. Ngokuqonda ukwakheka kwamangqamuzana kanye ne-hydrogen bonding ye-isopropanol, ukuziphatha kwayo ngaphansi kwezimo ezihlukahlukene kungabikezelwa futhi kulawulwe kangcono. Ezinqubweni zezimboni, izici zamaphuzu abilayo ze-isopropanol zingasetshenziswa ukuze kuthuthukiswe ukusetshenziswa kwamandla nokwandisa umkhiqizo. Elabhorethri, ukucabangela iphuzu lokubilisa le-isopropanol kuqinisekisa ukusebenza kahle kokuhlolwa nokuphepha kokusebenza. Ngakho-ke, indawo yokubilisa ye-isopropanol iyipharamitha ebalulekile okungafanele inganakwa kukho kokubili ukukhiqizwa kwamakhemikhali nocwaningo lwesayensi.
