Mtengo Wabwino Wopanga Triphenylmethane three isocyanate (ethyl acetate solution) CAS: 141-78-6 Mtundu: Desmodur_RE

1. Ethyl acetate imagwiritsidwa ntchito ngati chosungunulira cha varnish, lacquers, ndi nitrocellulose; ngati kukoma kwa zipatso zopangidwira; poyeretsa nsalu; komanso popanga silika wochita kupanga ndi zikopa, zonunkhira, ndi mafilimu ojambula zithunzi ndi mbale (Merck 1996). Ethyl Acetate nthawi zambiri imagwiritsidwa ntchito ngati chosungunulira mu zochita zachilengedwe. Zodetsa zachilengedwe; Zodetsa chakudya.

2. Ethyl acetate imagwiritsidwa ntchito makamaka ngati chosungunulira ndi chosungunulira, chifukwa imakondedwa chifukwa cha mtengo wake wotsika, poizoni wotsika, komanso fungo labwino. Mwachitsanzo, imagwiritsidwa ntchito kwambiri kuyeretsa ma circuit board ndi m'ma varnish ena a misomali (acetone ndi acetonitrile zimagwiritsidwanso ntchito). Nyemba za khofi ndi masamba a tiyi zimakhala ndi chosungunulira ichi. Chimagwiritsidwanso ntchito mu utoto ngati choyambitsa kapena chowumitsa. [Chinthu chofunikira] Ethyl acetate imapezeka mu makeke, zonunkhira, ndi zipatso. Mu zonunkhira, imaphwa mwachangu, ndikusiya fungo la zonunkhira pakhungu lokha.
3 - 1 - Ntchito za mu labotale
Mu labotale, zosakaniza zokhala ndi ethyl acetate zimagwiritsidwa ntchito kwambiri mu column chromatography ndi extracts. Ethyl acetate siisankhidwa kawirikawiri ngati reaction solvent chifukwa imakonda kusungunuka ndi kusinthidwa kwa esterification.
3 – 2 - Kupezeka mu vinyo
Ethyl acetate ndiye ester yodziwika kwambiri mu vinyo, chifukwa ndi chinthu chopangidwa ndi asidi wodziwika bwino wachilengedwe — acetic acid, ndi ethyl alcohol yomwe imapangidwa panthawi yophika. Fungo la ethyl acetate limakhala lomveka bwino kwambiri mu vinyo wachinyamata ndipo limathandizira kuti anthu ambiri aziona "kubereka zipatso" mu vinyo.
3 - 3 - Wopha tizilombo toyambitsa matenda
Mu sayansi ya tizilombo, ethyl acetate ndi mankhwala othandiza kupumitsa tizilombo. Mu mtsuko wopha womwe uli ndi ethyl acetate, nthunzi imapha tizilombo tosonkhanitsidwa (nthawi zambiri tomwe ndi akuluakulu) mwachangu popanda kuwononga. Chifukwa chakuti si hygroscopic, ethyl acetate imasunganso tizilombo tofewa mokwanira kuti tilole kuti tiike bwino pamalo oyenera.

3. Chithandizo cha mankhwala (kukoma); zinthu zopangira zipatso; zosungunulira za nitrocellulose, vanishi, lacquers, ndi zinthu zopangidwa ndi ndege; kupanga ufa wopanda utsi, chikopa chopangira, mafilimu ojambula zithunzi ndi mbale, silika wopangira, zonunkhira; nsalu zotsukira, ndi zina zotero.
