Ukuhlaziywa kwe-Ethy acetate Boiling Point Anailhlazi: Izici eziyisisekelo kanye nezinto ezithonya
I-Ethyl Acetate (EA) iyindawo evamile ye-organic enezicelo ezahlukahlukene. Isetshenziswa kakhulu njenge-solvent, ukunambitha kanye nesengezo sokudla, futhi kuthandelwe ukuguquguquka kwayo nokuphepha okuhlobene. Ukuqonda izakhiwo eziyisisekelo nezinto ezithinta iphuzu elibilayo le-Ethy acetate kubalulekile ukuze kusetshenziswe ekukhiqizweni kwezimboni.
Izici eziyisisekelo zomzimba ze-Ethyl Acetate
I-Ethyl Acetate iluketshezi olungenamibala ngephunga elimnandi elifana nephunga elimnandi. Inefomula ye-molecular c₄h₈o₂ kanye nesisindo samangqamuzana esingu-88.11 g / mol.Iphuzu elibilayo le-ethyl acetate ngu-77.1 ° C (350.2 k) engcindezini yasemkhathini. Leli phuzu elibilayo lenza kube lula ukuhwamuka ekushiseni kwekamelo, okwenza lilungele ukusetshenziswa ezinhlotsheni ezahlukahlukene zohlelo lokusebenza lapho kutholakala khona umhwamuko ngokushesha.
Izici ezithinta iphuzu elibilayo le-Ethyl Acetate

Umphumela wengcindezi yangaphandle:

Iphuzu elibilayo le-ethyl acetate lihlobene kakhulu nengcindezi ekhona. Ekucindezelweni okujwayelekile komkhathi, iphuzu elibilayo le-ethylo acetate ngu-77.1 ° C. Kodwa-ke, njengoba ingcindezi iyancipha, iphuzu elibilayo lincipha ngokufanele. Le mpahla ibaluleke kakhulu kwizicelo zezimboni, ikakhulukazi ekuhlolweni kwe-Vacuum, lapho iphuzu lokubilisa le-Ethyl Acetate lingancishiswa kakhulu, ngaleyo ndlela lithinte ukusebenza kahle kwenqubo yokuhlanza.

Umphumela wokumsulwa nengxube:

Ubumsulwa be-ethyl acetate buye bube nomthelela endaweni yayo ebilayo. Ukuhlanzeka okuphezulu kwe-ethyl acetate kunephuzu elibi elizinzile elingashintsha lapho lixubene namanye ama-solvents noma amakhemikhali. Into ye-azeotropy ye-azeotropy ye-mixtures yisibonelo esijwayelekile, lapho inani elithile le-acetate ye-ethylo exutshwe namanzi i-ingxube enendawo ethile ye-azeotropic, ebangela leyo ngxube ukuthi ivele ndawonye kulolo lokushisa.

Ukusebenzisana kwe-intermolecular:

Ukusebenzisana kwe-intermolecular, njenge-hydrogen bonding noma amabutho we-van der Waals, abuthakathaka ku-ethyl acetate kodwa abe nomphumela ocashile endaweni yawo ebilayo. Ngenxa yokwakheka kweqembu le-Ester ku-ethy actetate molecule, amabutho we-vanmolecular van der Waals amancane, aphumela endaweni ephansi ebilayo. Ngokuphambene, izinto ezinokusebenzisana okunamandla kwe-intermolecular okuvame ukuba namaphoyinti aphezulu abilayo.

Iphuzu elibilayo le-ethyl acetate embonini

I-Ethyl Acetate inendawo ebilayo engu-77.1 ° C, impahla eholele ekusetshenzisweni kwayo okubanzi njenge-solvent embonini yamakhemikhali, ikakhulukazi ekukhiqizeni upende, izimbotshana kanye nokunamathela. Iphoyinti layo eliphansi eliphansi livumela i-ethyy actate ukuthi ivele ngokushesha, ihlinzeka ngokuhleleka okuhle nokuphathwa kalula. Embonini yezemithi, i-ethyl acetate isetshenziselwa ukukhishwa kanye nokuhlanzwa kwamakhompiyutha ezi-organic, njengoba iphuzu lalo elilinganiselayo livumela ukuhlukaniswa okusebenzayo kwamakhompiyutha okuqondiwe nokungcola.

Ukufingqa

Ukuqonda iphuzu elibilayo le-ethylo acetate kanye nezici ezithonya kubalulekile ukuze kukhiqizwe kanye nesicelo embonini yamakhemikhali. Ngokulawula kahle ingcindezi ekhona, elawula ukuhlanzeka kwezinto ezibonakalayo, futhi kucatshangelwa ukusebenzisana kwe-intermolecular, ukusebenza kahle kokusetshenziswa kwe-ethyl acetate kungalungiselelwe kahle. Iqiniso lokuthi i-ETYL ACETATE inendawo ebilayo ka-77.1 ° C yenza kube yi-solvent ebalulekile futhi icumule ezinhlelweni eziningi zezimboni.
