Ntau Lawm Cov Khoom Siv
Cov ntaub ntawv raw ntawm acetylaniline ntau lawm suav nrog aniline thiab acetone. Ntawm lawv, Aniline yog cov duab uas muaj ntxhiab tsw qab, yog ib qho tseem ceeb tshaj tawm cov ntaub ntawv raw, siv tshuaj, siv hluav taws xob, roj hmab thiab lwm thaj chaw. Acetone, raws li tus neeg sawv cev acetylation, yog qhov nruab nrab tseem ceeb hauv kev lag luam fermentation thiab cov tshuaj yooj yim hauv thaj teb cov khoom siv hluav taws xob.
Acetanilide yog feem ntau tsim los ntawm acetylation, uas yog cov tshuaj tiv thaiv ntawm Aniline thiab Acetone los ua acetanilide. Cov tshuaj tiv thaiv feem ntau nqa tawm nyob rau hauv muaj cov alkaline catalysts xws li sodium hydroxide lossis hydroxyam, thiab cov tshuaj tiv thaiv kub feem ntau 80-100 ℃. Nyob rau hauv cov tshuaj tiv thaiv, acetone ua raws li acetylation, hloov lub hydrogen atom nyob rau hauv ib tug aniline molecule nrog tus acetyl pab los ua acetanilide. Tom qab cov tshuaj tiv thaiv tiav, muaj txiaj ntsig purity acetanilide tuaj yeem tau los ntawm acid neutralization, pom thiab lwm yam thev naus laus zis.
