Nhanganyaya
Trans-4-bromo-2-butenoic acid methyl ester imvura isina ruvara ine kunhuhwirira kwakakosha. Iine density inosvika 1.49g/cm3, painofashaira ingangoita 171-172°C, uye kupenya kunosvika 67°C. Haina kunyungudika mumvura pane tembiricha yemumba, asi inosanganiswa ne organic solvents senge ethanol, ether, nezvimwe.
Shandisa:
Trans-4-bromo-2-butenoic acid methyl ester inonyanya kushandiswa seyepakati mune organic synthesis reactions. Inogona kushandiswa kugadzira mamwe organic komisheni, semuenzaniso kuumbwa kwemakemikari mumakemikari emishonga uye kemisiti yezvipembenene.
Kugadzirira nzira:
Trans-4-bromo-2-butenoic acid methyl ester inowanzogadzirirwa nebromination reaction uye esterification reaction. Butene inotanga kubatwa nebromine kuti ipe 4-bromo-2-butene, iyo inobva yaiswa esterified ne methanol kupa trans-4-bromo-2-butenoic acid methyl ester.
Zvekuchengetedza
Trans-4-bromo-2-butenoic acid methyl ester imhando ye organic solvent uye kemikari raw material, ine imwe njodzi. Inotsamwisa uye inoparadza, uye kubata neganda, maziso kana kufema kunogona kukonzera kutsamwa nekukuvara. Kubata kwakananga kunofanirwa kudziviswa panguva yekushandiswa, uye kudzivirirwa kwakakodzera kwekufema uye zvipfeko zvinodzivirira zvinofanirwa kutorwa. Mukuwedzera, kutarisirwa kunofanira kutorwa kudzivirira kusangana neoxidants uye yakasimba acids panguva yekuchengetedza kudzivirira maitiro ane ngozi. Kana iwe uchida kushandisa komboni iyi, ndapota shanda munzvimbo yakachengeteka uye uteedzere nzira dzakachengeteka dzekushanda.
