N,N-dihydroxyethyl-p-methylaniline yog ib qho organic intermediate siv dav rau dyes, tshuaj thiab tshuaj tua kab. Cov ester pawg ntawm cov amino pawg kawg muab cov yam ntxwv zoo dua no. Txij li thaum nws npaj, nws yeej ib txwm nyob hauv ib qho kev lag luam. Tam sim no, qhov kev thov hauv tsev yog loj heev, thiab tseem muaj qee qhov peev xwm ua lag luam txawv teb chaws. Kev kawm txog nws cov synthesis thiab technology muaj txiaj ntsig zoo rau kev lag luam thiab kev siv.

Txoj kev sib xyaw ua ke
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 ntawm Chemicalbook mus rau 60 ℃ ~ 65 ℃, do rau 30 feeb, thiab ntxiv ethylene oxide Ntxiv 100g ntawm alkane thiab khaws qhov kub ntawm 65-70 ° C rau 4 teev. Tom qab ntawd ntxiv 100g ntawm ethylene oxide hauv 4 teev, khaws qhov kub ntawm 70-75 ° C, tshuaj tiv thaiv ntawm 70-80 ° C rau 3 teev tom qab dhau los, thiab txias rau 30 ° C. Ntxiv cov tshuaj tiv thaiv rau 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.
