Ntho e Belang ea Ethyl Acetate: Tlhahlobo e Feletseng le Lintho Tse Susumetsang
Ethyl acetate ke motsoako oa organic o sebelisoang haholo indastering ea lik'hemik'hale, ea meriana le ea malapeng. Ho utloisisa thepa ea 'mele ea ethyl acetate, haholo-holo ntlha ea eona e belang, ke ea bohlokoa bakeng sa taolo ea ts'ebetso le ts'ebetso ea ts'ebeliso. Ka pampiri ena, re tla sheba ka botebo ntlha e belang ea ethyl acetate le ho hlahloba lintlha tse sa tšoaneng tse e susumetsang.
1. Ntho e belang ea ethyl acetate
Ethyl acetate e na le ntlha e belang ea 77.1 ° C (170.8 ° F). Thepa ena ea 'mele e lumella ethyl acetate ho bonts'a lisebelisoa tse ntle haholo tsa ho qhibiliha lits'ebetsong tse ngata tsa indasteri, haholo-holo lits'ebetsong tse hlokang mouoane oa mocheso o bohareng, joalo ka ho lokisoa ha liphahlo le li-adhesives. Thepa e batlang e le tlase e belang ea 77.1 ° C e bolela hore ethyl acetate e fetoha mouoane ka potlako ha e futhumala ho ea ho mocheso o bohareng, e fana ka mouoane o sebetsang hantle le ho omisa lits'ebetsong tsa indasteri.
2. Lintlha tse amang ntlha e belang ea ethyl acetate
Le hoja ntlha e belang e tloaelehileng ea ethyl acetate e le 77.1 ° C, ntlha ea eona e belang e ka angoa ke lintlha tse 'maloa tsa ka ntle. Tse latelang ke tse ling tsa litšusumetso tse kholo:

Khatello: Khatello e na le phello e tobileng sebakeng se belang sa ethyl acetate. Ka tloaelo, ho eketseha ha khatello ho fella ka ntlha e phahameng ea ho belisa, ha ho fokotseha ha khatello ho fella ka ntlha e tlaase ea ho bela. Ka mohlala, nakong ea ho fokotsa khatello ea khatello, ho theola khatello ea tsamaiso ho ka fokotsa haholo ntlha e belang ea ethyl acetate, e leng se etsang hore ho be le karohano ea mocheso o tlaase oa distillation.

Bohloeki: Ho hloeka ha ethyl acetate hape ke e 'ngoe ea lintlha tsa bohlokoa tse amang ntlha ea eona e belang. Ka tloaelo, ha bohloeki bo phahame, sebaka se belang se haufi le boleng ba 77.1°C. Haeba ethyl acetate e na le litšila kapa li-solvents tse ling, ntlha ea sebele e belang e ka 'na ea kheloha boleng bo tloaelehileng, ho itšetlehile ka mofuta oa motsoako.

Metsoako: Ethyl acetate hangata e kopantsoe le li-solvents tse ling, 'me ho hlophisoa ha metsoako e joalo ho na le phello e kholo sebakeng sa eona se belang. Ka mohlala, ha e kopantsoe le ethanol kapa metsi, ntlha e belang ea motsoako e fapana ho ea ka boholo le ho sebelisana ha likaroloana, 'me phapang ena e ka boleloa esale pele ka setšoantšo sa mohato.

3. Bohlokoa le tšebeliso ea ntlha e belang ea ethyl acetate
Ho utloisisa le ho laola ntlha e belang ea ethyl acetate ke ea bohlokoa bakeng sa lits'ebetso tse 'maloa tsa indasteri. Lefapheng la meriana, moo ethyl acetate e atisang ho sebelisoa e le ho arabela le ho hloekisa solvent, taolo e nepahetseng ea ntlha e belang e thusa ho etsa bonnete ba tlhahiso ea lithethefatsi e sebetsang hantle le e sireletsehileng. Ka indasteri ea ho roala, ho hloka botsitso ha ethyl acetate ho ama ka ho toba lebelo la ho omisa le boleng ba filimi ea ho qetela ea liaparo. Bakeng sa ts'ebetso ea tlhahiso ea lik'hemik'hale tse ling tse ntle, taolo e nepahetseng ea ntlha e belang e ka boela ea ntlafatsa bohloeki le chai ea sehlahisoa. 4.
4. Mokhoa oa ho laola ntlha e belang ea ethyl acetate
Ho ntlafatsa ts'ebeliso ea ethyl acetate lits'ebetsong tsa indasteri, ho bohlokoa ho laola ntlha ea eona e belang. Mekhoa e tloaelehileng ea ho laola e kenyelletsa:

Ho fetola khatello ea tsamaiso: Ka ho sebelisa lisebelisoa tse fokotsehileng tsa khatello, hoa khoneha ho fetoha mouoane le ho arola ethyl acetate ka mocheso o tlaase, kahoo ho boloka matla le ho qoba tšenyo ea lintho tse senyang mocheso ho tloha mocheso o phahameng.

Ho khetha bohloeki bo nepahetseng ba solvent: Ka moralo oa ts'ebetso, ho khetha bohloeki bo phahameng ba ethyl acetate ho ka fokotsa ho fetoha ha ntlha e belang le ho netefatsa ts'ebetso e tsitsitseng ea tlhahiso.

Ntlafatso ea karo-karolelano ea motsoako: Moo motsoako oa ethyl acetate o hlokahalang, ntlha e belang ka kakaretso ea motsoako e ka lokisoa ho fihlela litlhoko tse khethehileng tsa ts'ebetso ka ho ntlafatsa karolelano ea likarolo.

Kakaretso
Ntho e belang ea ethyl acetate ke e 'ngoe ea bohlokoa ka ho fetisisa ea thepa ea eona ea' mele, e amang ka ho toba ts'ebetsong ea eona lits'ebetsong tsa indasteri. Kutloisiso e phethahetseng ea ntlha e belang ea ethyl acetate le lintlha tse e amang e tla nolofalletsa tšebeliso e ntle ea motsoako ona le ho ntlafatsa katleho ea ts'ebetso ea tlhahiso le boleng ba sehlahisoa. Ha e le hantle, tsebo ea liphello tsa liphetoho khatellong, bohloeki le motsoako sebakeng se belang sa ethyl acetate ke mokhoa oa bohlokoa oa ho ntlafatsa mekhoa ea ts'ebetso.
