N,N-dihydroxyethyl-p-methylaniline is a widely used organic intermediate for dyes, medicines and pesticides. The ester group on the terminal amino group gives this type of dye more excellent properties. Since its preparation, it has Has always occupied a certain market.

N,N-dihydroxyethyl-p-methylaniline can be synthesized by the following steps: add 1000g p-methylaniline and 10g water into a 5L pressure kettle, raise the temperature to 60°C ~ 65°C and stir for 30 minutes, then add 100g of ethylene oxide , keep the temperature at 65~70℃ for 4h. Then add 100g of ethylene oxide Chemicalbook within 4 hours, keep the temperature at 70-75°C, react at 70-80°C for 3 hours after passing through, and cool to 30°C. Add the reaction solution to the distillation kettle and collect the product at 143~148°C (1.3~1.6kPa). The yield is 86% and the product purity is greater than 98%. The front fraction can be recycled to increase the yield. The product is a light yellow solid.
