Isingeniso

I-Ethyl trans-butenoate iyinhlanganisela yezinto eziphilayo. Okulandelayo yisethulo sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha kwenhlanganisela:

 

Ikhwalithi:

I-Ethyl trans-butenoate iwuketshezi olungenambala olunephunga elingavamile. Iminyene kancane kunamanzi anesisindo esingu-0.9 g/mL. Incibilika ezinhlobonhlobo zezinyibilikisi eziphilayo, njenge-ethanol, ama-ethers nama-naphthenes, ekamelweni lokushisa.

 

Sebenzisa:

I-Ethyl trans-butenate inezinhlelo zokusebenza ezahlukahlukene embonini yamakhemikhali. Ukusetshenziswa okuvame kakhulu kufana nokuphakathi kokuhlangana kwe-organic ukuze kulungiswe ezinye izinhlanganisela eziphilayo, njenge-oxalates, i-ester solvents kanye nama-polymers. Ingasetshenziswa futhi njengezingubo zokugqoka, izithasiselo zenjoloba, nezincibilikisi.

 

Indlela:

Indlela yokulungiselela ye-trans-butenoate ethyl ester ngokuvamile itholakala ngokusabela kwe-trans-butenoic acid nge-ethanol. Lo mkhiqizo utholakala ngokushisisa i-trans-butenic acid ne-ethanol ngaphansi kwezimo ezine-asidi ukuze kwakhiwe i-ester.

 

Ulwazi Lokuphepha:

I-Ethyl trans-butenoate iyacasula emehlweni nasesikhumbeni futhi ingabangela ukuvuvukala kwamehlo nesikhumba. Ukuhogela umhwamuko wawo kufanele kugwenywe lapho uphatha inhlanganisela, futhi imisebenzi kufanele yenziwe endaweni enomoya omuhle. Lapho uyigcina, kufanele ibekwe esitsheni esingangeni moya, kude nokushisa kanye nama-oxidizer.
