3 – 1 - Fa'aoga ile fale su'esu'e
I totonu o fale su'esu'e, o fa'afefiloi o lo'o i ai le ethyl acetate e masani ona fa'aogaina ile koluma chromatography ma fa'aputuga.E seasea filifilia le Ethyl acetate e fai ma vaifofo tali aua e faigofie ile hydrolysis ma trans esterification.
3 – 2 - E tutupu i uaina
O le Ethyl acetate o le ester sili ona taatele i le uaina, o se mea e maua mai i le vailaʻau faʻasolosolo masani - acetic acid, ma le ethyl alcohol e gaosia i le taimi o le faʻafefe.O le manogi o le ethyl acetate e sili ona manino i uaina laiti ma fesoasoani i le malamalama lautele o le "fua" i le uaina.
3 – 3 - So'o fa'amamateina
I le matata o le entomology, o le ethyl acetate o se faʻamaʻi aoga mo le faʻaogaina i le aoina ma suʻesuʻega iniseti.I totonu o se fagu fasioti tagata ua molia i le ethyl acetate, o ausa o le a faʻaumatia vave le iniseti aoina (masani tagata matua) e aunoa ma le faʻaumatia.Talu ai e le o le hygroscopic, o le ethyl acetate e faʻamalu ai le iniseti e faʻataga ai le faʻapipiʻiina talafeagai mo se aoina.
3. Fesoasoani tau vaila'au (tofo);fuala'au fua;solvent mo nitrocellulose, varnishes, lacquers, ma dopes vaalele;gaosiga o le pauta e leai se asu, pa'u fa'apitoa, ata tifaga ma ipu, siliki fa'afu, manogi;fa'amama ie, ma isi.
