Chemical Properties:

Ethyl acetate (chimiro chakaratidzwa pamusoro) ndiyo inonyanya kuzivikanwa ester kune vakawanda chemistry vadzidzi uye pamwe iyo ester ine yakakura kwazvo yekushandiswa.Ester inotorwa kubva mucarboxylic acids nekutsiva iyo acidic hydrogen nealkyl kana aryl boka.Ethyl acetate pachayo imvura isina ruvara patembiricha yemumba ine kunhuhwirira kwakanaka kwe "fruity", bp 77°C.

Ethyl acetate ine zvakawanda zvekushandisa, senge zvekugadzira michero essences uye anonhuwirira, artificial flavour ye confectionery, ice cream nemakeke, sechinhu chinonyungudutsa mune zvakawanda zvinoshandiswa (kusanganisira decaffeinating tii nekofi) yevarnish uye pendi (nail varnish remover), uye kugadzirwa kweingi dzokudhinda nepefiyumu.

Application:

Ethyl acetate inonyanya kushandiswa sechinhu chinonyungudutsa uye chakasviba, ichifarirwa nekuda kwekudhura kwayo, kuderera kwehuturu, uye kunhuhwirira kunofadza.Semuenzaniso, inowanzoshandiswa kuchenesa mapuranga ematunhu uye mune dzimwe misumari yevarnish inobvisa (acetone uye acetonitrile inoshandiswawo).Kofi bhinzi uye mashizha etii ane decaffeinated ne solvent iyi.Inoshandiswawo mumapendi se activator kana hardener.[citation inodiwa] Ethyl acetate inowanikwa mu confectionery, perfume, uye michero.Muzvinonhuhwirira, inobuda nekukurumidza, ichisiya chete hwema hwemafuta paganda.
3 - 1 - Kushandiswa kweLabhoritari
Murabhoritari, misanganiswa ine ethyl acetate inowanzoshandiswa mukoramu chromatography uye zvakatorwa.Ethyl acetate haiwanzo kusarudzwa seyakagadziriswa solvent nekuti inowanzoita hydrolysis uye trans esterification.
3 - 2 - Kuitika muwaini
Ethyl acetate ndiyo yakajairika ester muwaini, ichive chigadzirwa cheanonyanya kuvhurika organic acid - acetic acid, uye ethyl doro rinogadzirwa panguva yekuvirisa.Kunhuhwirira kwe ethyl acetate kunonyanya kujeka muwaini madiki uye kunobatsira kune yakajairika maonero e "zvibereko" muwaini.
3 - 3 - Entomological kuuraya mumiririri
Mumunda we entomology, ethyl acetate inobudirira asphyxiant yekushandiswa mukuunganidza zvipembenene uye kudzidza.Muchirongo chekuuraya chinopomerwa ne ethyl acetate, mhute inouraya yakaunganidzwa (kazhinji yakakura) zvipembenene nokukurumidza pasina kuiparadza.Nekuda kwekuti haisi hygroscopic, ethyl acetate zvakare inochengeta chipembenene chakapfava zvekubvumidza kukwira kwakakodzera kuunganidzwa.
