Txoj kev khaws cia
1. Khaws rau hauv qhov chaw txias thiab cua txias. Nyob deb ntawm qhov hluav taws kub thiab qhov chaw kub. Nws yuav tsum tau muab cais los ntawm oxidants, txo cov neeg ua haujlwm, acids, thiab txo cov neeg ua haujlwm, thiab kev sib xyaw cia yuav tsum zam. Siv cov khoom sib xws thiab ntau npaum li cas ntawm cov khoom siv tua hluav taws. Lub chaw cia khoom yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog kom muaj cov khoom xau.
2. Cov reagents rau cov khoom no yog ntim rau hauv iav fwj, txhua qhov hnyav 25g, thiab yuav tsum tau muab cia rau hauv lub thawv kaw.
txheej txheem hluavtaws
Nws tuaj yeem tau txais los ntawm kev ua haujlwm ethyl cyanoacetate nrog ammonia. Txias ethyl cyanoacetate kom qis dua 200 degree, ntxiv cov dej ntshiab ammonia rau cov tshuaj tiv thaiv, thiab tau txais cov sib tov uas hloov ntawm turbid mus rau ntshiab. Tom qab txias hauv dej txias rau 20 feeb, precipitate yog precipitated. Tom qab pom thiab ziab, crude cyanoacetate tau txais. Tom qab ntawd, ntxiv me me ntawm cov pa roj carbon activated rau decolorization thiab refinement, lim, thiab txias cov lim kom precipitate. Tom qab ziab, qhuav ntawm 80-100 degree kom tau txais cyanoacetate zoo.
