Mawu Oyamba
Ethyl trans-butenoate ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha pawiri:
Ubwino:
Ethyl trans-butenoate ndi madzi opanda mtundu okhala ndi fungo lachilendo. Ndiwonenepa pang'ono kuposa madzi okhala ndi kachulukidwe ka 0.9 g/mL. Kusungunuka mu mitundu yosiyanasiyana ya organic solvents, monga Mowa, etha ndi naphthenes, firiji.
Gwiritsani ntchito:
Ethyl trans-butenate ili ndi ntchito zosiyanasiyana pamakampani opanga mankhwala. Ambiri ntchito ndi monga wapakatikati mu kaphatikizidwe organic pokonza zina organic mankhwala, monga oxalates, ester solvents ndi ma polima. Itha kugwiritsidwanso ntchito ngati zokutira, zopangira mphira, ndi zosungunulira.
Njira:
Njira yokonzekera trans-butenoate ethyl ester nthawi zambiri imapezeka ndi zomwe trans-butenoic acid ndi ethanol. Mankhwalawa amapezedwa ndi kutentha kwa trans-butenic acid ndi ethanol pansi pa acidic kuti apange ester.
Zambiri Zachitetezo:
Ethyl trans-butenoate imakwiyitsa maso ndi khungu ndipo imatha kuyambitsa kutupa kwa maso ndi khungu. Kukoka mpweya wake nthunzi ayenera kupewa pogwira pawiri, ndipo ntchito ziyenera kuchitikira pamalo mpweya wabwino. Mukasunga, iyenera kuyikidwa mu chidebe chopanda mpweya, kutali ndi kuyatsa ndi oxidizer.
