1. Ethyl acetate e faʻaaogaina e avea o se solvent mo varnishes, lacquers, ma nitrocellulose;e pei o fualaau aina suamalie;i le fa'amamāina o 'ie; ma le gaosiga o siliki ma le pa'u, mea manogi, ma ata tifaga ma ipu (Merck 1996).O le Ethyl Acetate e masani ona faʻaaogaina e avea o se solvent i gaioiga faʻasolosolo.Fa'alesiosiomaga;Fa'aleaga mea'ai.

2. Ethyl acetate e faʻaaogaina muamua e avea o se solvent ma diluent, e fiafia i ai ona o lona tau maualalo, maualalo oona, ma le manogi malie.Mo se faʻataʻitaʻiga, e masani ona faʻaaogaina e faʻamamā ai laupapa faʻasalalau ma i nisi o fao varnish aveese (e faʻaaogaina foi le acetone ma le acetonitrile).O fatu kofe ma lau lauti o lo'o fa'afefeteina i lenei solvent. E fa'aaogaina fo'i i vali e fai ma fa'agaoioiga po'o fa'ama'a'a.I mea manogi, e vave alu ese, ae na o le manogi o le manogi i luga o le paʻu.
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.
