Boiling Point yeEthyl Acetate: Kuongorora Kwakazara uye Kufurira Zvinhu
Ethyl acetate ndeye organic compound inoshandiswa zvakanyanya mumaindasitiri emakemikari, emishonga uye emumba. Kunzwisisa zvimiro zvemuviri zve ethyl acetate, kunyanya kubikira kwayo, kwakakosha pakudzora kwemaitiro uye kushandiswa kwekushandisa. Mupepa rino, tichatarisa zvakadzama pairi kuvira kwe ethyl acetate uye kuongorora zvinhu zvakasiyana-siyana zvinoikonzera.
1. Boiling point ye ethyl acetate
Ethyl acetate ine poindi yekuvira inosvika 77.1°C (170.8°F). Iyi pfuma yemuviri inobvumira ethyl acetate kuratidza yakanakisa kunyungudutsa maitiro mune akawanda maindasitiri maitiro, kunyanya mumashandisirwo anoda epakati tembiricha evaporation, senge kugadzirira kwekuputira uye adhesives.Iyo yakaderera kubikira poindi ye77.1 ° C inoreva kuti ethyl acetate inoputika nekukurumidza kana ichipisa kusvika pakati tembiricha, ichipa evaporation inoshanda uye kuomesa mumaindasitiri maitiro.
2. Zvinhu zvinokanganisa nzvimbo yekubikira ye ethyl acetate
Kunyange zvazvo chiyero chekubika che ethyl acetate chiri 77.1 ° C, nzvimbo yayo yekuvira inogona kukanganiswa nehuwandu hwekunze kwezvinhu. Izvi zvinotevera zvishoma zvezvikuru zvinofurira:

Dzvinyiriro: Dzvinyiriro ine mhedzisiro yakananga pane yekubikira poindi ye ethyl acetate. Kazhinji, kuwedzera kwekumanikidzika kunoguma kune imwe nzvimbo yekubikira, nepo kuderera kwekumanikidza kunoguma kune yakaderera yekuvira. Semuyenzaniso, panguva yakadzikira kudzvinyirirwa distillation, kudzikisa kudzvanywa kwehurongwa kunogona kudzikisa zvakanyanya kuvira kwe ethyl acetate, zvichikonzera kuderera kwekushisa distillation kuparadzaniswa.

Kuchena: Kuchena kwe ethyl acetate zvakare chimwe chezvinhu zvakakosha zvinokanganisa kubikira kwayo. Kazhinji, kuchena kwepamusoro, ndiko kuswedera pedyo kwekubikira kuri kune kukosha kwetioretical ye 77.1 ° C. Kana iyo ethyl acetate ine tsvina kana zvimwe zvinonyungudutsa, iyo chaiyo yekubikira inogona kutsauka kubva kune yakajairika kukosha, zvichienderana nemhando yemusanganiswa.

Misanganiswa: Ethyl acetate inowanzosanganiswa nemamwe masolvents, uye kuumbwa kwemisanganiswa yakadaro kune simba guru pane iyo inopisa. Semuenzaniso, kana yakasanganiswa ne ethanol kana mvura, nzvimbo yekubikira yemusanganiswa inosiyana zvichienderana nekuenzana uye kupindirana kwezvikamu, uye kusiyana uku kunogona kufanotaurwa nechikamu chechikamu.

3. Kukosha uye kushandiswa kwekubikira kwe ethyl acetate
Kunzwisisa uye kudzora nzvimbo yekubikira ye ethyl acetate kwakakosha kune akati wandei maindasitiri ekushandisa. Muindasitiri yemishonga, uko ethyl acetate inowanzoshandiswa seyekuita uye kucheneswa solvent, kutonga kwakaringana kwenzvimbo yekubikira kunobatsira kuve nechokwadi chekugadzira zvinodhaka uye zvakachengeteka. Muindasitiri yekuputira, kushata kwe ethyl acetate kunokanganisa zvakananga kumhanya kwekuomesa uye yekupedzisira firimu mhando yejasi. Pakugadzirwa kwemamwe makemikari akanaka, kutonga kwakaringana kwekubikira kunogona zvakare kuvandudza kuchena uye goho rechigadzirwa. 4.
4. Nzira yekudzora sei kuvira kwe ethyl acetate
Kuti uwedzere kushandiswa kwe ethyl acetate mumaindasitiri ekushandisa, zvakakosha kudzora nzvimbo yayo yekubikira. Common control nzira dzinosanganisira:

Kugadzirisa kudzvanywa kwehurongwa: Nekushandisa yakaderedzwa dhizaini distillation midziyo, zvinokwanisika kubuda uye kupatsanura ethyl acetate pakudzika kwakadzika, nekudaro kuchengetedza simba uye kudzivirira kukuvadzwa kwezvinhu zvinopisa-sensitive kubva kune tembiricha yakakwira.

Kusarudza iyo chaiyo solvent kuchena: Mukugadzira dhizaini, kusarudza yakakwira kuchena ethyl acetate kunogona kuderedza kubikira kushanduka uye kuve nechokwadi chekuenderana kwekugadzira maitiro.

Musanganiswa ratio optimization: Painodiwa ethyl acetate musanganiswa, iyo yakazara yekubikira poindi yemusanganiswa inogona kugadziridzwa kuti isangane nezvinodiwa maitiro nekugadzirisa chiyero chezvikamu.

Summary
Iyo yekubikira poindi ye ethyl acetate ndeimwe yeakanyanya kukosha ezvimiro zvayo zvemuviri, izvo zvinokanganisa zvakananga kuita kwayo mumaindasitiri ekushandisa. Kunyatsonzwisisa kweiyo yekubikira poindi ye ethyl acetate uye zvinhu zvinoikanganisa zvinogonesa kushandiswa kuri nani kweiyi koniyuta uye kuwedzera kushanda kwemaitiro ekugadzira uye kunaka kwechigadzirwa. Mukuita, ruzivo rwemhedzisiro yekuchinja mukumanikidza, kuchena uye musanganiswa pane inofashaira poindi ye ethyl acetate inzira yakakosha yekugonesa maitiro paramita.
