Ethyl Acetate Boiling Point Analysis: Thepa ea Motheo le Lintho Tse Susumetsang
Ethyl Acetate (EA) ke motsoako o tloaelehileng oa manyolo o nang le mefuta e mengata ea lisebelisoa. Hangata e sebelisoa e le mokelikeli, tatso le motsoako oa lijo, 'me e ratoa ka lebaka la ho hloka botsitso le polokeho e lekanyelitsoeng. Ho utloisisa thepa ea motheo le lintlha tse amang ntlha e belang ea ethyl acetate ke ea bohlokoa bakeng sa tšebeliso ea eona tlhahiso ea indasteri.
Lintho tsa Motheo tsa 'Mele tsa Ethyl Acetate
Ethyl acetate ke mokelikeli o se nang 'mala o nang le monko o monate o kang oa tholwana. E na le mokhoa oa molek'hule C₄H₈O₂ le boima ba molek'hule ea 88.11 g / mol. Sebaka se belang sa ethyl acetate ke 77.1 ° C (350.2 K) khatello ea sepakapaka. Sebaka sena sa ho bela se etsa hore ho be bonolo ho fetoha mouoane mochesong oa kamore, ho etsa hore e loketse ho sebelisoa maemong a fapaneng a ts'ebeliso moo ho hlokahalang hore ho be le mouoane o potlakileng.
Lintlha tse amang ntlha e belang ea ethyl acetate

Phello ea khatello ea kantle:

Sebaka se belang sa ethyl acetate se amana haufi-ufi le khatello ea tikoloho. Ka khatello e tloaelehileng ea sepakapaka, ntlha e belang ea ethyl acetate ke 77.1°C. Leha ho le joalo, ha khatello e fokotseha, ntlha e belang e fokotseha ka tsela e nepahetseng. Thepa ena e bohlokoa haholo lits'ebetsong tsa indasteri, haholo-holo ka vacuum distillation, moo ntlha e belang ea ethyl acetate e ka fokotsoang haholo, kahoo e ama katleho ea karohano le mokhoa oa ho hloekisa.

Phello ea bohloeki le motsoako:

Bohloeki ba ethyl acetate bo boetse bo na le phello sebakeng sa eona se belang. Bohloeki bo phahameng ba ethyl acetate bo na le sebaka se batlang se tsitsitse se belang se ka fetohang ha se kopantsoe le li-solvents tse ling kapa lik'hemik'hale. Ketsahalo ea azeotropy ea metsoako ke mohlala o tloaelehileng, moo likarolo tse itseng tsa ethyl acetate tse kopantsoeng le metsi li etsang motsoako o nang le ntlha e itseng ea azeotropic, e leng se etsang hore motsoako o fetohe mouoane hammoho mocheso oo.

Litšebelisano tsa limolek'hule:

Litšebelisano tsa limolek'hule, tse kang hydrogen bonding kapa van der Waals forces, li batla li fokola ho ethyl acetate empa li ntse li na le phello e poteletseng sebakeng sa eona se belang. Ka lebaka la sebopeho sa sehlopha sa ester ka molek'hule ea ethyl acetate, matla a intermolecular van der Waals a batla a le manyane, a fella ka ntlha e tlaase ea ho bela. Ka lehlakoreng le leng, lintho tse nang le litšebelisano tse matla tsa li-intermolecular hangata li na le lintlha tse belang tse phahameng.

Sebaka se belang sa ethyl acetate indastering

Ethyl acetate e na le ntlha e belang ea 77.1 ° C, thepa e lebisitseng ho sebelisoa ha eona ho pharaletseng e le mokelikeli oa lik'hemik'hale oa lik'hemik'hale, haholo-holo tlhahiso ea lipente, liphahlo le li-adhesives. Sebaka sa eona se tlaase se belang se lumella ethyl acetate hore e fetohe mouoane ka potlako, e fana ka solubility e ntle le boiketlo ba ho sebetsana le eona. Lefapheng la meriana, ethyl acetate e atisa ho sebelisoa bakeng sa ho ntša le ho hloekisa metsoako ea lintho tse phelang, kaha ntlha ea eona ea ho belisa e itekanetseng e lumella ho arohana hantle ha metsoako e reretsoeng le litšila.

Ho akaretsa

Ho utloisisa ntlha e belang ea ethyl acetate le lintlha tse e susumetsang ke ea bohlokoa bakeng sa tlhahiso le tšebeliso ea indasteri ea lik'hemik'hale. Ka ho laola ka nepo khatello ea tikoloho, ho laola bohloeki ba lintho tse bonahalang, le ho nahanela litšebelisano tsa li-intermolecular, katleho ea tšebeliso ea ethyl acetate e ka ntlafatsoa ka katleho. Taba ea hore ethyl acetate e na le ntlha e belang ea 77.1 ° C e etsa hore e be mokelikeli oa bohlokoa le o bohareng lits'ebetsong tse ngata tsa indasteri.
