Wopanga mtengo wabwino Trihenylhane atatu a istonate (ethyl acetate solution) Cas: 141-78-6 Brand: Desmoder_re

1.thyl acetate imagwiritsidwa ntchito ngati zosungunulira ya varnishes, machesi, ndi nitrocellulose; ngati zipatso za zipatso; M'makalata oyeretsa; ndipo popanga silika wambiri, zonunkhira, ndi zithunzi zojambula (Merck 1996). Ethyl acetate nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira mu zomwe zimachitika mwamphamvu. Zodetsa zachilengedwe; Chakudya chodetsa nkhawa.

Acetate acetate amagwiritsidwa ntchito ngati zosungunulira komanso zokupatsani mphamvu chifukwa cha mtengo wake wotsika, zoopsa zochepa, komanso fungo labwino. Mwachitsanzo, nthawi zambiri amagwiritsidwa ntchito kuyeretsa matabwa ozungulira ndipo m'malo ena amisala (acetone ndi acetonitrile amagwiritsidwanso ntchito). Nyemba za khofi ndi masamba a tiyi zimawonetsedwa ndi zosungunulira izi. M'mafuta onunkhira, imasuntha mwachangu, kusiya fungo la zonunkhira pakhungu.
3 - 1 - imagwiritsa ntchito labotale
Mu labotale, zosakanikirana zomwe zili ndi ethyl acetate nthawi zambiri zimagwiritsidwa ntchito mu gawo la chromatography. Ethyl acetate samakonda kusankha ngati solation yochita chifukwa imakonda kuwononga hydrolysis ndi kutsatsa kutulutsa.
3 - 2 - Zochitika mu Vinyo
Ethyl acetate ndi ester yofala kwambiri mu vinyo, kukhala chinthu cha ortic acid - acetic acid, ndi ethyl mowa wopangidwa pa nayonso. Mafuta a ethyl acetate amakhala owoneka bwino kwambiri mu ma vinner achichepere ndipo amathandizira kuzindikira kwa "zipatso" mu vinyo.
3 - 3 - Kupha Wothandizira
Pamunda wa etrom, ethyl acetate ndi wothandiza kwambiri kuti azigwiritsa ntchito kutolera ndi kuphunzira. Mu mtsuko wakupha wophedwa ndi ethyl acetate, nthunzi imapha omwe adasonkhanitsidwa (nthawi zambiri wamkulu) Tizilombo mwachangu popanda kuwononga. Chifukwa si hygroscopic, ethyl acetate imasunganso tizilombo toyambitsa matenda mokwanira kuti zilolere kukweza bwino koyenera kusonkhanitsa.

3.Fermaceutic (kununkhira); Zipatso zopanga; zosungunulira kwa nitrocellulose, ma varnisoses, mabungwe, ndi zikwangwani za ndege; Kupanga ufa wopanda utsi, chikopa chochita kupanga, mafilimu ojambula ndi mbale, silika, zonunkhira; kuyeretsa malembedwe, etc.
