Nhanganyaya
Ethyl trans-butenoate ndeye organic compound. Inotevera sumo yezvivakwa, mashandisiro, nzira dzekugadzirira uye ruzivo rwekuchengetedza kwekomboni:
Hunhu:
Ethyl trans-butenoate imvura isina ruvara ine kunhuhwirira kwakasiyana. Yakakora zvishoma pane mvura ine density ye 0.9 g/mL. Soluble mumhando dzakasiyana-siyana organic solvents, senge ethanol, ethers uye naphthenes, pakamuri tembiricha.
Shandisa:
Ethyl trans-butenate ine akasiyana ekushandisa muindasitiri yemakemikari. Iyo inonyanya kushandiswa ndeye yepakati mune organic synthesis yekugadzirira kwemamwe maokisi emakemikari, senge oxalates, ester solvents uye mapolymers. Inogonawo kushandiswa semajasi, majekiseni erabha, uye zvinonyungudutsa.
Nzira:
Nzira yekugadzirira ye trans-butenoate ethyl ester inowanzowanikwa nekuita kwe trans-butenoic acid ne ethanol. Ichi chigadzirwa chinowanikwa nekupisa trans-butenic acid uye ethanol pasi pemamiriro e acidic kugadzira ester.
Zvekuchengetedza
Ethyl trans-butenoate inogumbura maziso neganda uye inogona kukonzera kuzvimba kwemaziso neganda. Kufema kwehuputi hwayo kunofanirwa kudziviswa kana uchibata musanganiswa, uye mashandiro anofanirwa kuitwa munzvimbo inofefetera. Paunenge uchichengeta, inofanira kuiswa mumudziyo usina mhepo, kure nekupisa uye oxidizers.
