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

1.Ethyl acetate imagwiritsidwa ntchito ngati chosungunulira cha ma varnish, lacquers, ndi nitrocellulose;monga chibadwa zipatso kukoma;poyeretsa nsalu; komanso kupanga silika ndi zikopa, zonunkhiritsa, ndi mafilimu ndi mbale zazithunzi (Merck 1996).Ethyl Acetate nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira muzochita za organic.Zowononga zachilengedwe;Zowononga zakudya.

2.Ethyl acetate imagwiritsidwa ntchito makamaka ngati zosungunulira ndi zosungunulira, zoyamikiridwa chifukwa cha mtengo wake wotsika, kawopsedwe kakang'ono, ndi fungo labwino.Mwachitsanzo, nthawi zambiri amagwiritsidwa ntchito kuyeretsa matabwa ozungulira komanso zochotsera misomali (acetone ndi acetonitrile amagwiritsidwanso ntchito).Nyemba za khofi ndi masamba a tiyi ali ndi caffeine ndi zosungunulirazi. Amagwiritsidwanso ntchito mu utoto monga activator kapena hardener.Mu zonunkhiritsa, amasanduka nthunzi mofulumira, kusiya fungo la mafutawo pakhungu.
3 - 1 - Kugwiritsa ntchito Laboratory
Mu labotale, zosakaniza zomwe zimakhala ndi ethyl acetate zimagwiritsidwa ntchito kwambiri muzambiri za chromatography ndi zotulutsa.Ethyl acetate sichimasankhidwa kawirikawiri ngati chosungunulira chifukwa chimakonda hydrolysis ndi trans esterification.
3 - 2 - Zomwe zimachitika mu vinyo
Ethyl acetate ndiye ester yodziwika kwambiri mu vinyo, yomwe imapangidwa ndi asidi osakhazikika - acetic acid, ndi mowa wa ethyl womwe umapangidwa panthawi yowitsa.Kununkhira kwa ethyl acetate kumawoneka bwino kwambiri mu vinyo wachichepere ndipo kumathandizira kuti pakhale lingaliro la "chipatso" mu vinyo.
3 - 3 - Entomological kupha wothandizira
Pankhani ya entomology, ethyl acetate ndi asphyxiant yogwira ntchito posonkhanitsa ndi kuphunzira.Mumtsuko wakupha wokhala ndi ethyl acetate, nthunzi imapha tizilombo tosonkhanitsidwa (nthawi zambiri wamkulu) popanda kuwononga.Chifukwa si hygroscopic, ethyl acetate imathandizanso kuti tizilombo ting'onoting'ono kuti tiyike bwino kuti titengere.

3.Pharmaceutic thandizo (kununkhira);zopangira zipatso essences;zosungunulira za nitrocellulose, vanishi, lacquers, ndi dopes ndege;kupanga ufa wopanda utsi, zikopa zopangira, mafilimu ndi mbale, silika wopangira, mafuta onunkhira;kuyeretsa nsalu, etc.
