It can be used in the phenolic resin, plasticizer, pharmaceuticals, disinfectants, pesticides, dyes, lubricants, etc. This paper mainly introduces the properties and usage, main production methods, market prospect and development trend of 2,4xylenol, and designs the production process of 2,4-xylenol with annual output of 500 tons.2,4-dimethyl aniline as raw material, after diazotization, then hydrolysis. 2,4-xylenol was got. In process design, I mainly responsible for 2,4-xylenol rectification tower design. According to the result of material balance, the process parameters of 2,4-xylenol distillation and the tower body type and feature sizes were determined. Keywords: 2, 4-xylenol; Packing type rectifying column; The relative volatility. - 2 -
