1. Ethyl acetate e sebediswa e le tharollo bakeng sa di-varnish, di-lacquer, le nitrocellulose; e le tatso ya ditholwana tse sa etswang; ho hlwekiseng masela; le tlhahisong ya silika ya maiketsetso le letlalo, dinkgisamonate, le difilimi tsa difoto le dipoleiti (Merck 1996). Ethyl Acetate hangata e sebediswa e le tharollo dikarabelong tsa tlhaho. Ditshila tsa tikoloho; Ditshila tsa dijo.

2. Ethyl acetate e sebediswa haholoholo e le solvent le diluent, e ratwa haholo ke theko ya yona e tlase, chefo e tlase, le monko o monate. Mohlala, e sebediswa hangata ho hlwekisa diboto tsa potoloho le ho tse ding tsa di-varnish tsa manala (acetone le acetonitrile le tsona di a sebediswa). Dinawa tsa kofi le mahlaku a tee di se na caffeine ka solvent ena. E boetse e sebediswa penteng e le activator kapa hardener.[ho hlokahala qotso] Ethyl acetate e teng di-confectionery, di-perfume le ditholwana. Di-perfume, e fetoha mouoane kapele, e siya monko wa perfume feela letlalong.
3 – 1 - Tšebeliso ea laboratori
Ka laboratoring, metsoako e nang le ethyl acetate e atisa ho sebelisoa ho chromatography ea kholomo le ho ntšoa ha lintho. Ethyl acetate ha e khethoe hangata e le tharollo ea karabelo hobane e na le tšekamelo ea ho haelloa ke hydrolysis le transesterification.
3 – 2 - Ho etsahala diveineng
Ethyl acetate ke ester e tloaelehileng haholo veineng, kaha ke sehlahisoa sa asiti e tloaelehileng ea tlhaho e feto-fetohang - acetic acid, le joala ba ethyl bo hlahisoang nakong ea ho belisoa. Monko oa ethyl acetate o hlakile haholo liveineng tse nyane 'me o tlatsetsa kutloisisong e akaretsang ea "litholoana" veineng.
3 – 3 - Sebolai sa likokoanyana
Lefapheng la thuto ea likokoanyana, ethyl acetate ke sesebelisoa se sebetsang sa ho thibela ho bola ha likokoanyana le ho li ithuta. Ka nkho e bolaeang e nang le ethyl acetate, mouoane o tla bolaea kokoanyana e bokelletsoeng (hangata e hōlileng) kapele ntle le ho e senya. Kaha ha e hygroscopic, ethyl acetate e boetse e boloka kokoanyana e le bonolo ho lekana ho lumella ho kenngoa hantle ho loketseng pokello.
