Ukuhlaziywa okuningiliziwe kwephuzu lokubilisa le-methanol
I-Methanol ingenye yezinto zokusetshenziswa ezibaluleke kakhulu embonini yamakhemikhali, futhi isetshenziswa kabanzi njengophethiloli, i-solvent kanye ne-chemical synthesis. Kuleli phepha, sizohlaziya ngokuningiliziwe udaba lwe- "Methanol Boiling Point", futhi sixoxe ngokujulile ngezakhiwo ezibonakalayo ze-methanol, izici ezithinta indawo yayo yokubilisa kanye nokubaluleka kwayo ekusetshenzisweni kwezimboni.
Izici eziyisisekelo zomzimba ze-methanol
I-Methanol, eyaziwa nangokuthi i-wood alcohol noma i-wood spirit, ifomula yamakhemikhali ye-CH₃OH, iyinhlanganisela elula yotshwala. Njengoketshezi olungenambala, oluvuthayo, i-methanol iguquguquka kakhulu futhi inobuthi obukhulu. Iphuzu layo lokubilisa liyipharamitha ebalulekile yokuqonda izakhiwo ze-methanol. Engcindezini yomoya, i-methanol inephuzu lokubila elingu-64.7°C (148.5°F), okwenza kube lula ukuhwamuka ekamelweni lokushisa. Ngakho-ke, lapho uphatha futhi ugcina i-methanol, kubalulekile ukucabangela ukuguquguquka nokuvutha kwayo futhi uthathe izinyathelo ezifanele zokuphepha.
Izinto Ezithinta Iphuzu Elibilayo Le-Methanol
Kunezici eziningana okufanele zicatshangelwe lapho uqonda indaba "yephuzu lokubilisa le-methanol". Isakhiwo samangqamuzana e-methanol sinquma indawo yayo yokubila ephansi. I-molecule ye-methanol iqukethe iqembu le-methyl (CH₃) neqembu le-hydroxyl (OH) futhi inesisindo esiphansi samangqamuzana. Ngenxa yokuba khona kwe-hydrogen bonding eqenjini le-hydroxyl, lokhu kuphakamisa iphuzu layo lokubilisa ngandlela-thile, kodwa lisephansi kunobunye uphuzo oludakayo olunesisindo samangqamuzana esiphezulu.
Izimo zangaphandle ezifana noshintsho ekucindezelweni zingaphinde zithinte indawo yokubilisa ye-methanol. Ngaphansi kwezimo eziphansi zokucindezela, indawo yokubilisa ye-methanol iyancipha, kanti ngaphansi kwezimo zokucindezela okukhulu, iyanda. Ngakho-ke, kungase kudingeke ukulawula ukuhwamuka kwe-methanol kanye nenqubo ye-condensation ngokulungisa ukucindezela ezinkambisweni ezahlukene zezimboni.
Ukubaluleka kwendawo yokubilisa ye-methanol ezinhlelweni zezimboni
Iphuzu lokubilisa le-methanol libalulekile ekusetshenzisweni kwalo ekukhiqizeni amakhemikhali. Isibonelo, ekukhiqizeni i-methanol kanye nokukhishwa kwe-distillation, kubalulekile ukulawula izinga lokushisa elifanele kanye nokucindezela kokuhlukaniswa okuphumelelayo nokuhlanzwa kwe-methanol. Ngenxa yephuzu layo eliphansi lokubilisa, i-methanol ingahwamuka ekucindezelweni komkhathi kusetshenziswa imishini yokushisisa evamile, enenzuzo ngokonga izindleko zamandla.
Indawo yokubilisa ephansi ye-methanol iphinda iyenze ibe isinyibiliki esifanele, ikakhulukazi ezinhlelweni ezidinga ukuhwamuka okusheshayo, njengamapende nezihlanzi. Ngesikhathi sokusetshenziswa, izinga lokushisa kanye nokungena komoya endaweni yokusebenza kudinga ukulawulwa ngokuqinile ukuze kuvinjelwe ukunqwabelana komhwamuko we-methanol, ngaleyo ndlela kugwenywe izingozi zomlilo noma zezempilo.
Isiphetho
Kusukela ekuhlaziyweni okungenhla, kungabonakala ukuthi ukuqonda “iphoyinti lokubilisa le-methanol” kubalulekile ukuze kusetshenziswe i-methanol ngendlela ephephile futhi ephumelelayo emisebenzini yezimboni. Iphuzu lokubilisa le-methanol alithinti nje kuphela izakhiwo zayo ezingokomzimba nezimo zokusebenza, kodwa futhi lihlobene ngokuqondile nokukhethwa nokusetshenziswa kwalo ekusetshenzisweni kwamakhemikhali okuhlukahlukene. Lolu lwazi lusiza ukuthuthukisa izinqubo zezimboni, ukonga amandla nokwandisa ukusebenza kahle kokukhiqiza.
