| Ethyl 2, 3-dicyanopropionate Siv Thiab Synthesis |
| Synthesis | Txoj kev npaj ntawm Ethyl 2,3-dicyanopropionate yog ntxiv cov tshuaj potassium cyanide thiab ethyl cyanoacetate rau hauv cov tshuaj tiv thaiv lub khob, siv dimethyl sulfoxide ua hnyav, maj mam ntxiv cov tshuaj formaldehyde rau cov tshuaj, thiab tswj cov tshuaj tiv thaiv kub ntawm 5 degree tom qab. Qhov sib ntxiv, cov tshuaj tiv thaiv tau txuas ntxiv ntawm 20 degree rau 15h, tom qab ntawd cov tshuaj tiv thaiv tau ntxiv rau cov dej khov dej, cov txheej txheem organic tau muab cais tawm, cov txheej txheem dej tau muab rho tawm nrog cov kuab tshuaj, cov txheej txheem organic tau sib xyaw, qhuav thiab desolubilized kom tau txais cov txheej txheem dej. khoom. Reaction sib npaug: HCHO+KCN+CNCH2COOC2H5 → CNCH2-CHCNCOOC2H5 |
