N, N-dihydroxyethyl-p-methylaniline yog siv dav hauv cov organic nruab nrab rau dyes, tshuaj thiab tshuaj tua kab. Cov ester pawg ntawm lub davhlau ya nyob twg amino pawg muab hom dye zoo tshaj plaws. Txij li thaum nws npaj, nws yeej ib txwm nyob hauv ib qho kev lag luam

N, N-dihydroxyethyl-p-methylaniline tuaj yeem ua ke los ntawm cov kauj ruam hauv qab no: ntxiv 1000g p-methylaniline thiab 10g dej rau hauv 5L siab kettle, nce qhov kub ntawm 60 ° C ~ 65 ° C thiab do rau 30 feeb, ces ntxiv. 100g ntawm ethylene oxide, khaws qhov kub ntawm 65 ~ 70 ℃ rau 4h. Tom qab ntawd ntxiv 100g ntawm ethylene oxide Chemicalbook hauv 4 teev, khaws qhov kub ntawm 70-75 ° C, hnov ​​​​mob ntawm 70-80 ° C rau 3 teev tom qab dhau mus, thiab txias rau 30 ° C. Ntxiv cov tshuaj tiv thaiv rau cov dej distillation thiab sau cov khoom ntawm 143 ~ 148 ° C (1.3 ~ 1.6kPa). Cov txiaj ntsig yog 86% thiab cov khoom purity ntau dua 98%. Cov ntu pem hauv ntej tuaj yeem rov ua dua los ua kom cov qoob loo nce ntxiv. Cov khoom yog lub teeb daj daj.
