Cov khoom siv raw
Cov khoom siv raw ntawm acetylaniline ntau lawm suav nrog aniline thiab acetone. Ntawm lawv, aniline yog ib qho tshuaj tsw qab amine, yog ib qho tseem ceeb tshaj plaws organic chemical raw cov ntaub ntawv, dav siv nyob rau hauv dyes, tshuaj, hluavtaws resins, roj hmab thiab lwm yam teb. Acetone, raws li tus neeg sawv cev acetylation, yog ib qho tseem ceeb nruab nrab hauv kev lag luam fermentation thiab cov tshuaj lom neeg hauv kev ua haujlwm ntawm cov 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 lub xub ntiag ntawm alkaline catalysts xws li sodium hydroxide los yog hydroxylamine, thiab cov tshuaj tiv thaiv kub yog feem ntau 80-100 ℃. Hauv cov tshuaj tiv thaiv, acetone ua raws li acetylation, hloov lub hydrogen atom hauv aniline molecule nrog acetyl pawg los tsim acetanilide. Tom qab cov tshuaj tiv thaiv tiav, cov khoom siv purity acetanilide siab tuaj yeem tau txais los ntawm acid neutralization, filtration thiab lwm yam txheej txheem thev naus laus zis.
Daim ntawv thov
1. Dye pigments: raws li ib qho nruab nrab siv rau hauv kev sib txuas ntawm cov xim xim, xws li luam ntawv thiab dyeing dyes, ntaub dyeing agents, zaub mov, tshuaj thiab lwm yam.
2. Tshuaj: Siv los ua raw cov ntaub ntawv nyob rau hauv synthesis ntawm tej yam tshuaj thiab kev kho mob compounds, xws li diuretics, analgesics thiab tshuaj loog.
3. Cov txuj lom: tuaj yeem siv los ua cov txuj lom hluavtaws, xws li cov tshuaj tsw qab.
4 hluavtaws cob: tuaj yeem siv los ua kom muaj ntau yam ntawm cov resins, xws li phenolic resin, urea formaldehyde resin, thiab lwm yam.
5. Txheej: tuaj yeem siv ua cov xim dispersant rau txheej, txhim kho lub zog ntawm cov xim ntawm cov xim thiab adhesion ntawm cov xim zaj duab xis.
6. Roj Hmab: tuaj yeem siv los ua cov khoom siv raw ntawm cov roj hmab hluavtaws, kuj tuaj yeem siv los ua cov roj hmab yas thiab tsis muaj.
Kev phom sij: Chav Kawm 6.1
1. Ua kom lub siab ua pa sab sauv.
2. Kev noj haus tuaj yeem ua rau muaj cov hlau thiab cov pob txha pob txha hyperplasia.
3. Kev rov tshwm sim tuaj yeem tshwm sim. Irritating rau ntawm daim tawv nqaij, tuaj yeem ua rau dermatitis.
4. Inhibition lub hauv nruab nrab lub paj hlwb thiab cov hlab plawv system.
5. Kev tiv tauj ntau yuav ua rau kiv taub hau thiab daj ntseg.
