3 – 1 - Ojiji ụlọ nyocha
N'ime ụlọ nyocha, ngwakọta nwere ethyl acetate na-ejikarị na kọlụm chromatography na mmịpụta.A naghị ahọrọ ethyl acetate dị ka ihe mgbaze mmeghachi omume n'ihi na ọ na-adịkarị mfe hydrolysis na trans esterification.
3 – 2 - Ime na mmanya
Ethyl acetate bụ ester kachasị na mmanya, ebe ọ bụ ngwaahịa nke organic acid na-agbanwe agbanwe - acetic acid, na mmanya ethyl na-emepụta n'oge ịgba ụka.Ihe na-esi ísì ụtọ nke ethyl acetate na-apụta ìhè na mmanya ndị na-eto eto ma na-enye aka n'echiche zuru ezu nke "mkpụrụ osisi" na mmanya.
3 – 3 - Onye na-ahụ maka igbu mmadụ
Na ngalaba nke entomology, ethyl acetate bụ asphyxiant dị irè maka iji na-achịkọta ụmụ ahụhụ na ọmụmụ ihe.N'ime ite igbu egbu nke eboro ethyl acetate, vapors ga-egbu ụmụ ahụhụ anakọtara (na-abụkarị okenye) ngwa ngwa n'emebighị ya.N'ihi na ọ bụghị hygroscopic, ethyl acetate na-emekwa ka ụmụ ahụhụ dị nro nke ọma iji kwe ka ịrị elu kwesịrị ekwesị maka nchịkọta.
