N,N-dihydroxyethyl-p-methylaniline yog ib qho organic intermediate siv dav rau cov xim, tshuaj thiab tshuaj tua kab. Pawg ester ntawm pawg amino kawg muab cov xim no zoo dua. Txij li thaum nws npaj, nws yeej ib txwm nyob hauv qee lub khw.

N,N-dihydroxyethyl-p-methylaniline tuaj yeem tsim los ntawm cov kauj ruam hauv qab no: ntxiv 1000g p-methylaniline thiab 10g dej rau hauv lub lauj kaub siab 5L, tsa qhov kub kom txog 60 ° C ~ 65 ° C thiab do rau 30 feeb, tom qab ntawd ntxiv 100g ntawm ethylene oxide, khaws qhov kub ntawm 65 ~ 70 ℃ rau 4 teev. Tom qab ntawd ntxiv 100g ntawm ethylene oxide hauv 4 teev, khaws qhov kub ntawm 70-75 ° C, teb ntawm 70-80 ° C rau 3 teev tom qab dhau los, thiab txias rau 30 ° C. Ntxiv cov tshuaj tiv thaiv rau hauv lub lauj kaub distillation thiab sau cov khoom ntawm 143 ~ 148 ° C (1.3 ~ 1.6kPa). Cov txiaj ntsig yog 86% thiab cov khoom ntshiab yog ntau dua 98%. Cov feem pem hauv ntej tuaj yeem rov ua dua tshiab kom nce cov txiaj ntsig. Cov khoom yog cov khoom daj daj.
