Methanol Density E Hlalositsoe: Litšobotsi, Tekanyo le Lintlha tse E Amang
Kakaretso ea Methanol Density
Methanol (molemo oa lik'hemik'hale: CH₃OH) ke lisebelisoa tsa bohlokoa tsa lik'hemik'hale, 'me boima ba eona ke parameter ea bohlokoa ea 'mele e lekanyang kamano ea eona le bongata ba bongata. Tsebo le kutloisiso ea sekhahla sa methanol li bohlokoa tlhahisong ea indasteri, ts'ebeliso ea lik'hemik'hale le lipalangoang. Hangata, density ke thepa ea tlhaho ea ntho 'me e amana haufi-ufi le maemo a kang mocheso le khatello. Sehloohong sena, re tla tšohla ka ho qaqileng thepa ea methapo ea methanol, mekhoa ea ho lekanya le lintlha tse e amang, ho u thusa ho utloisisa hamolemo parameter ena ea bohlokoa.
Thepa ea motheo ea letsoalo la methanol
Boima ba methanol hangata bo hlahisoa ho latela bophahamo ba yuniti ea methanol, 'me maemong a tloaelehileng (ke hore, 20°C le 1 atm), boima ba methanol bo ka ba 0.7918 g/cm³. Ke habohlokoa ho hlokomela hore boleng bona bo fapana le mocheso le khatello, kahoo boima bo ka 'na ba fapana hanyenyane tlas'a maemo a fapaneng a ho sebetsa. Ho utloisisa thepa ea mantlha ea letsoalo la methanol ho thusa ho metering e nepahetseng le taolong ea karabelo lits'ebetsong tsa lik'hemik'hale.
Lintlha tse amang letsoalo la methanol
Phello ea mocheso ho bongata ba methanol
Mocheso ke e 'ngoe ea lintlha tsa bohlokoa tse amang ho teteana ha methanol. Ha mocheso o ntse o eketseha, matla a kinetic a limolek'hule tsa methanol a eketseha 'me sebaka se pakeng tsa limolek'hule sea eketseha, e leng se bakang ho fokotseha ha sekhahla. Mohlala, mochesong oa kamore (20°C), methanol e na le tekano ea 0.7918 g/cm³, e theohelang ho hoo e ka bang 0.762 g/cm³ ha mocheso o nyolohela ho 60°C. Ho itšetlehile ka mocheso ona ho tlameha ho eloa hloko lits'ebetsong tse sebetsang, haholo-holo moo ts'ebetso ea mocheso o phahameng o amehang kapa moo molumo oa methanol o lokelang ho lekanngoa ka nepo.
Phello ea khatello ho bongata ba methanol
Le hoja phello ea khatello ho bongata ba mokelikeli hangata e le nyenyane, sebakeng sa khatello e phahameng ntlha ena e ke ke ea hlokomolohuoa. Khatello e ntseng e eketseha e qobella libaka tse pakeng tsa limolek'hule hore li fokotsehe, ka hona li eketsa sekhahla sa methanol. Bakeng sa mokelikeli o kang methanol, liphetoho tsa letsoalo ka lebaka la khatello hangata ha li hlake ho feta liphetoho tsa mocheso. Ka hona, phello ea khatello ho bongata ba methanol e ka nkoa e le ea bobeli tlas'a maemo a tloaelehileng a ts'ebetso, empa ntlha ena e ntse e lokela ho nkoa ka lisebelisoa tsa lik'hemik'hale tse phahameng.
Mekhoa ea ho lekanya bakeng sa letsoalo la methanol
Mokhoa oa ho lekanya laboratoring
Ka laboratoring, boima ba methanol hangata bo lekanngoa ho sebelisoa botlolo e itseng ea khoheli kapa densitometer. Mokhoa o ikhethileng oa botlolo ea matla a khoheli ke mokhoa oa khale oa ho lekanya density, moo boima bo baloang ka ho metha boima ba botlolo e itseng ea khoheli e tlatsitsoeng ka mokelikeli. Densitometer ke sesebelisoa se lekanyang ka ho otloloha ho teteana ha metsi le ho lekanya ho teteana ha metsi ka molao-motheo oa ho phaphamala ha liphaphatha. Mekhoa ena ka bobeli e na le melemo le melemo ea eona, ea pele e nepahetse haholo empa e boima ho e sebetsa, ea morao-rao e bonolo ho sebetsa empa e hloka ho lekanya holimo ha sesebelisoa.
Tekanyo ea marang-rang ea indasteri
Tlhahisong ea indasteri, tlhahlobo ea nako ea 'nete ea letsoalo la methanol e bohlokoa bakeng sa taolo ea ts'ebetso. Lisebelisoa tse tloaelehileng tsa ho lekanya li-densitometer tsa marang-rang li kenyelletsa li-tube densitometers le li-ultrasonic densitometers. Li-tube densitometers tse sisinyehang li etsa qeto ea ho ba le letsoalo ka ho lekanya maqhubu a resonant a mokelikeli ka har'a tube e sisinyehang, athe ultrasonic densitometers e fumana density ho tloha lebelo la maqhubu a ultrasonic a tsamaeang ka har'a mokelikeli. Lisebelisoa tsena li fana ka lintlha tsa nako ea sebele nakong ea ts'ebetso ea tlhahiso ho netefatsa hore maemo a ts'ebetso a ka har'a meeli e nepahetseng.
Boima ba methanol indastering ea lik'hemik'hale
Boikemisetso bo nepahetseng le taolo ea sekhahla sa methanol se na le mefuta e mengata ea likopo indastering ea lik'hemik'hale. Mohlala, ho boenjineri ba karabelo, density ke paramente ea bohlokoa ho accounting ea thepa le accounting ea matla. Ha u boloka le ho tsamaisa methanol, data ea density e ka thusa ho tseba bokhoni ba ho tlatsa litanka tsa polokelo le ho palamisa likoloi tsa lipalangoang. Lintlha tsa density li ka boela tsa sebelisoa ho lekola bohloeki ba methanol, kaha boteng ba litšila hangata bo lebisa mefuteng e sa tloaelehang ea letsoalo.
Kakaretso
Methanol density ke parameter ea bohlokoa indastering ea lik'hemik'hale, e amang likarolo tse 'maloa tsa ts'ebetso le moralo. Ka ho utloisisa thepa ea eona, mekhoa ea ho lekanya le lintlha tse susumetsang, litsebi tsa indasteri ea lik'hemik'hale li khona ho laola hantle ts'ebetso ea tlhahiso, ho ntlafatsa tšebeliso ea lisebelisoa le ho netefatsa polokeho le katleho ea tlhahiso. Ho leka-lekanya kutloisiso le ts'ebeliso ea letsoalo la methanol tlas'a maemo a fapaneng ke mokhoa oa bohlokoa oa ho ntlafatsa ts'ebetso ea indasteri.
