Ethyl acetate wowiritsa solicsis: Zoyambira Zoyambira ndi Zochititsa chidwi
Ethyl acetate (ea) ndi gawo lodziwika bwino ndi mapulogalamu osiyanasiyana. Nthawi zambiri imagwiritsidwa ntchito ngati zosungunulira, zokopa komanso zowonjezera chakudya, ndipo zimakondedwa chifukwa cha kusalakwirikira kwake komanso chitetezo. Kuzindikira zinthu zofunika komanso zinthu zomwe zikukhudza malo otentha a ethyl zimafunikira pakugwiritsa ntchito mafakitale.
Zoyambira zakuthupi za ethyl acetate
Ethyl acetate ndi madzi opanda utoto wokhala ndi fungo labwino ngati lonunkhira. Ili ndi mawonekedwe a ma molecular c₄h₈o₂ ndi kulemera kwa 88.11 g / mol. Malo owiritsa awa amapangitsa kuti zikhale zosavuta kutuluka kutentha, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito malo osiyanasiyana omwe amagwiritsidwa ntchito pomwe amafunikira.
Zinthu zomwe zimakhudza malo owiritsa a ethyl acetate

Zotsatira za kupanikizika kwakunja:

Malo owiritsa a ethyl acetate amagwirizana kwambiri ndi kupanikizika kozungulira. Pamavuto a m'mlengalenga, malo otentha a ethyl acetate ndi 77.1 ° C. Komabe, pamene kupanikizika kumachepa, kuwiritsa kumatsika moyenerera. Katunduyu ndi wofunikira kwambiri m'magulu a mafakitale, makamaka pakuchepetsa disulum, kumene malo otentha a ethyl amatha kuchepetsedwa kwambiri, ndikukhudza kugwira ntchito kwa kulekanitsa ndi kuyeretsa kwa kuyeretsedwa kwa kupatukana ndi kuyeretsa.

Zotsatira za kuyera ndi osakaniza:

Kuyera kwa ethyl acetate nawonso kumathandizanso kuwira. Kuyera kwa ethyl acetate ali ndi malo okhazikika omwe amasintha pomwe amasakanizidwa ndi ma sol sol osakanikirana kapena mankhwala. Phenomenon of Azeotropy of osabereka ndi chitsanzo chabwino, momwe magawo ena a ethyl acetate wosakanizidwa ndi osakaniza ndi malo osakanikirana, zomwe zimapangitsa kusakaniza kwapa.

Zogwirizana:

Kulumikizana kwa pakati, monga momwe ma hydrogen ogwiritsira ntchito hydrogen kapena a van der walders ankhondo, ndi ofooka mu ethyl acetate koma akadakhala ndi vuto la owotchera. Chifukwa cha fuko la gulu la Ethyl acetate molekyulu, kung'ambika kwa van van der ankhondo ndi yaying'ono, zomwe zimapangitsa kutsika pang'ono. Mosiyana ndi izi, zinthu zokhala ndi zibwenzi zolimba pakati pawo zimakhala ndi mfundo zochulukirapo.

Malo otentha a ethyl acetate m'makampani

Ethyl acetate ali ndi malo otentha a 77.1 ° C, malo omwe adapangitsa kuti azigwiritsa ntchito popanga mankhwala mu makampani ogulitsa mankhwala, makamaka popanga utoto, zomata ndi zomatira. Malo ake ozizira amalola kuti ethyl acetate kuti atuluke mwachangu, kupereka malo osungunuka bwino komanso osavuta kugwiritsa ntchito. M'makampani opanga mankhwala, ethyl acetate amagwiritsidwa ntchito pochotsera komanso kuyeretsa kwa organic mankhwala, popeza malo ake owiritsa owotcha amalola kudzipatula kwa ma tarports ndi zosayera.

Kufotokozera mwachidule

Kumvetsetsa malo otentha a ethyl acetate ndi zinthu zomwe zimapangitsa kuti ndizofunikira pakupanga ndikugwiritsa ntchito pamakampani. Mwakuwongolera bwino kukakamizidwa, kuwongolera zoyera zakuthupi, ndikugwiritsa ntchito kuyanjana kwadzidzidzi, mphamvu ya ethyl ya ethyl imatha kukhala yokhazikika. Chowonadi chakuti ethyl acetate ali ndi gawo lotentha la 77.1 ° C limapangitsa kuti ikhale yofunikira komanso yapakatikati mu mafakitale ambiri.
