Synthesis ntawm 4-aminophenol:
4-aminophenol hmoovtuaj yeem tau los ntawm hydrolying p - nitroclorobzene rau sodium p} nitrophenol hauv sodium thiab hlau hmoov txo.
Sib tov sodium hydroxide mus rau hauv kev daws nrog kev sib xyaw ntawm cov nitrocyrirenzene, ntxiv rau hauv cov laujkev no, thiab lub siab ntxiv rau hauv lub hwj txwv yog 0.4-0.42mpa (gauge siab). Nres cua sov, thiab cov cua sov tso tawm los ntawm hydrolysis cov tshuaj tiv thaiv yuav ua kom sov thiab siab mus rau 165℃thiab 0.6mpa (gauge siab). Tom qab 3 teev ntawm cov tshuaj tiv thaiv, coj ib qho piv txwv rau kev tsom xam kom ua rau cov oily feem<0.5%, and then hydrolyze to the endpoint.
Txias rau 120 degree. Ntxiv dej thiab 98% concentrated sulfuric acid mus rau thawj lub lauj kaub siv tshuab crystallization rau hauv nws thiab txias nws mus rau 50-55 degree. Ntxiv cov sulfuric sulfuric acid los ua cov ntawv congo liab mus kuaj, txuas ntxiv mus txias rau 30 degree, thiab lim nws mus rau hauv ib qho chaw qhuav.
Ntxiv cov kab ntawv kawg ntawm kev lim thiab lim cov kua cawv ntawm para aminophenol rau hauv cov hmoov av kom zoo thiab 30% nws ntxiv cov hlau hlau thiab pararophenol nyob rau hauv boiling xeev. Thaum lub sij hawm cov txheej txheem pub mis, nyob ntawm cov kev tawm tsam (xws li dhau ntawm lub lauj kaub), txias ua kom zoo nkauj cawv tuaj yeem ntxiv.
Kev txo lub rhaub rau qhov kawg (cov tshuaj tiv thaiv kev tawm ntawm daim ntawv lim dawb, thiab lub nplhaib pom kev yuav tsum yog xim tsis muaj xim). Ntxiv ib qho nyiaj ntawm kub niam kub niam thiab cov tshuaj khib nyiab thiab magnesium kom txog thaum tsis muaj hlau ions hauv cov tshuaj tiv thaiv.
Cia nws sawv ntsug rau 30 feeb, tso cov kua ntshiab, lim tus niam dej cawv nrog 98℃crystallization los tsim cov av nkos, thiab ncuav cov frystallization kettle.
Cov lauj kaub thib ob crystall yog txias rau 60-65℃li 4 teev, thiab tom qab ntawd muab tso rau hauv lub txias txias rau 25℃li ntawm 4 teev, thiab centrifuge thiab lim. Npaj cov sodium bisulfite tov nrog cov ntsiab lus li ntawd ntawm 4% rau 5% hauv lub lim dej ua kom zoo, thiab qhuav cov khoom siv airflow kom tau cov khoom lag luam ua tiav ntawm para aminophenol. Lub ntsej muag zoo nkauj Niam cawv yuav siv sijhawm thaum lub sijhawm txuas ntxiv ntawm kev txo qis.
