Igiciro cyiza cy'umusaruro Triphenylmethane isocyanate eshatu (umuti wa ethyl acetate) CAS: 141-78-6 Ikirango: Desmodur_RE

1. Ethyl acetate ikoreshwa nk'umusemburo mu mavanishi, lacquers, na nitrocellulose; nk'uburyohe bw'imbuto; mu gusukura imyenda; no mu gukora ubudodo bw'ubukorano n'uruhu, imibavu, na filimi z'amafoto n'amasahani (Merck 1996). Ethyl acetate ikoreshwa muri rusange nk'umusemburo mu bikorwa by'ibinyabuzima. Ibintu byanduza ibidukikije; Ibintu byanduza ibiribwa.

2. Ethyl acetate ikoreshwa cyane cyane nk'umusemburo n'umuti ugabanya ubushyuhe, ikunzwe cyane kubera ko ihendutse, uburozi buke, n'impumuro nziza. Urugero, ikoreshwa cyane mu gusukura imiyoboro ya circuit no mu bikoresho bimwe na bimwe bikuraho inzara (acetone na acetonitrile nabyo birakoreshwa). Ibishyimbo bya kawa n'amababi y'icyayi bivangwa na iyi solvent. Ikoreshwa kandi mu marangi nk'umusemburo cyangwa umukomere. [Icyitonderwa] Ethyl acetate iboneka mu byuma bitunganya ibinure, imibavu, n'imbuto. Mu mibavu, irashira vuba, igasiga impumuro y'iyo parufe gusa ku ruhu.
3 – 1 - Imikoreshereze ya laboratwari
Muri laboratwari, uruvange rurimo ethyl acetate rukunze gukoreshwa muri chromatography y'inkingi no mu gusohora. Ethyl acetate ntabwo ikunze gutoranywa nk'umusemburo w'ibisubizo kuko ishobora kwangirika no guhindurwa kwa trans esterification.
3 – 2 - Kugaragara muri divayi
Ethyl acetate ni ester ikunze kugaragara muri divayi, ikaba ari umusaruro wa aside organic ikunze kugaragara cyane - aside asetiki, na alcohol ya ethyl ikorwa mu gihe cyo guhinga. Impumuro ya ethyl acetate igaragara cyane muri divayi nto kandi igira uruhare mu kumva muri rusange "imbuto" muri divayi.
3 – 3 - Udukoko twica udukoko
Mu rwego rw'udukoko, ethyl acetate ni umuti ufasha mu gukurura no gusesengura udukoko. Mu kibindi cyica kirimo ethyl acetate, umwuka wica udukoko twakusanyijwe (ubusanzwe dukuze) vuba utadushenye. Kubera ko atari hygroscopic, ethyl acetate ikomeza koroha bihagije kugira ngo yemererwe gushyirwaho neza.

3. Ubufasha mu by'imiti (uburyohe); ibirungo by'imbuto z'ubukorano; umuti ukoreshwa mu gukora nitrocellulose, varnish, lacquers, n'ibindi bikoresho by'indege; gukora ifu idafite umwotsi, uruhu rw'ubukorano, amafoto n'amasahani, silk y'ubukorano, imibavu; imyenda yo gusukura, nibindi.
