Ibikoresho bya Shimi:

Ethyl acetate (imiterere yerekanwe hejuru) niyo ester imenyerewe kubanyeshuri benshi ba chimie kandi birashoboka ko ester ifite intera nini yo gukoresha.Esters ikomoka muburyo bwa acide karubike isimbuza hydrogène acide na alkyl cyangwa itsinda rya aryl.Ethyl acetate ubwayo ni amazi atagira ibara mubushyuhe bwicyumba afite impumuro nziza "imbuto", bp 77 ° C.

Ethyl acetate ifite byinshi ikoreshwa, nkibintu byimbuto byimbuto hamwe niyongerera impumuro nziza, uburyohe bwa artile kubirungo, ice cream na keke, nkigisubizo mubisabwa byinshi (harimo icyayi cya kawa hamwe nikawa) kubisiga amarangi (kuvanaho imisumari). gukora inkingi zo gucapa na parufe.

Gusaba:

Ethyl acetate ikoreshwa cyane cyane nkigishishwa kandi cyoroshye, gutoneshwa kubera igiciro cyacyo gito, uburozi buke, numunuko wemewe.Kurugero, isanzwe ikoreshwa mugusukura imbaho ​​zumuzunguruko no mubintu bimwe na bimwe bivanaho imisumari (acetone na acetonitrile nabyo birakoreshwa).Ikawa n'ibabi by'icyayi byandujwe n'iki gishishwa.Bikoreshwa kandi mu marangi nk'umukangurambaga cyangwa ukomantaje.Muri parufe, ihinduka vuba, hasigara gusa impumuro ya parufe kuruhu.
3 - 1 - Gukoresha Laboratoire
Muri laboratoire, imvange zirimo Ethyl acetate zikoreshwa mubisanzwe muri chromatografiya no kuyikuramo.Ethyl acetate ntikunze gutoranywa nkigisubizo cya reaction kuko ikunda hydrolysis na trans esterification.
3 - 2 - Ibibaho muri vino
Ethyl acetate ni ester ikunze kugaragara muri vino, kuba umusaruro wa acide organic ihindagurika cyane - acide acike, na alcool ya Ethyl ikorwa mugihe cya fermentation.Impumuro ya Ethyl acetate iragaragara cyane muri divayi ikiri nto kandi igira uruhare mubitekerezo rusange by "imbuto" muri vino.
3 - 3 - Umukozi wica Entomologiya
Mu rwego rwa entomologiya, Ethyl acetate ni umwuka mwiza wo gukoresha mu gukusanya udukoko no kwiga.Mu kibindi cyo kwica kiregwa Ethyl acetate, imyuka izica udukoko twakusanyije (ubusanzwe abantu bakuru) tutiriwe tuyangiza.Kubera ko atari hygroscopique, Ethyl acetate nayo ituma udukoko tworoshe bihagije kugirango twemererwe neza bikwiye gukusanywa.
