Cov khoom siv raw tsim
Cov khoom siv raw ntawm acetylaniline feem ntau suav nrog aniline thiab acetone. Ntawm lawv, aniline yog ib qho aromatic amine, yog ib qho tseem ceeb tshaj plaws ntawm cov khoom siv organic tshuaj raw, siv dav hauv cov xim, tshuaj, cov khoom siv hluavtaws, roj hmab thiab lwm yam teb. Acetone, ua tus neeg sawv cev acetylation, yog ib qho tseem ceeb hauv kev lag luam fermentation thiab cov tshuaj yooj yim hauv kev lag luam organic synthesis.
Acetanilide feem ntau yog tsim los ntawm acetylation, uas yog cov tshuaj tiv thaiv ntawm aniline thiab acetone los tsim acetanilide. Cov tshuaj tiv thaiv feem ntau yog ua nyob rau hauv qhov muaj alkaline catalysts xws li sodium hydroxide lossis hydroxylamine, thiab qhov kub ntawm cov tshuaj tiv thaiv feem ntau yog 80-100 ℃. Hauv cov tshuaj tiv thaiv, acetone ua haujlwm ua acetylation, hloov cov hydrogen atom hauv aniline molecule nrog acetyl pawg los tsim acetanilide. Tom qab cov tshuaj tiv thaiv tiav lawm, cov khoom acetanilide purity siab tuaj yeem tau txais los ntawm acid neutralization, filtration thiab lwm yam txheej txheem thev naus laus zis.
