| Hazard Symbols | Xi – Hasha |
| Risk Codes | 36 – Kushungurudza maziso |
| Tsanangudzo Yekuchengetedza | 26 – Kana wasangana nemaziso, sukurudza nekukasira nemvura yakawanda uye tsvaga rubatsiro kuna chiremba. |
Nhanganyaya
asidhi ethyl ester ndeye organic compound ine kemikari formula C8H8BrNO2. Imvura isina ruvara ine kunhuhwirira kwakakosha. Mushonga wacho unonyungudika muorganic solvents senge ethanol, dimethylformamide uye benzene, uye isinganyungudike mumvura.
acid ethyl ester ine huwandu hwakawanda hwekushandisa mune organic synthesis. Inogona kushandiswa semushonga wepakati wepakati pekugadzirwa kwemhando dzakasiyana dzemishonga uye bioactive molecules. Mukuwedzera, inogona zvakare kushandiswa mukuita kweGormperman uye palladium-catalyzed cross-coupling reactions mune organic synthesis.
Pane nzira mbiri dzakajairika dzeasidhi ethyl ester:
1. Inowanikwa nekuita kwe6-bromopyridine uye chloroacetate, uyezve hydrolyzed nealkali mushure mekuita.
2. Ne 6-bromopyridine uye chloroacetic acid ester reaction, acid chloride, uye wobva waita nedoro kuti uwane chigadzirwa.
Chengetedzo yekudzivirira inodiwa paunenge uchishandisa nekuchengetedza asidhi ethyl ester. Imvura inobvira uye inofanira kuchengetwa munzvimbo inotonhorera, inofefetera zvakanaka, kure nemoto uye tembiricha yepamusoro. Midziyo yekudzivirira yakakodzera, senge magurovhosi erabhoritari uye gogi, inofanirwa kupfekwa panguva yekushanda. Kana ukanwa kana kubata neganda kana maziso, sukurudza nekukasika nemvura yakawanda uye tsvaga rubatsiro kuna chiremba.
