3,4-Dimethylphenol Usage
1、Because industrial xylenol is rich in 3,4-xylenol and 3,5-xylenol, it can be used as a source of 3,4-xylenol and 3,5-xylenol, and as a disinfectant, Raw materials for plasticizers and pesticides. 3,4-xylenol is used to prepare imine resins (engineering plastics), disinfectants, pesticides, dyes and fragrances. 3,5-xylenol is used as a disinfectant, insecticide, perfume, dye, antioxidant, raw material for synthetic resin, etc.
2、Used to make modified polyimides, pesticides, dyes, etc.
3,4-Dimethylphenol Production method
The crude phenol obtained from the washing oil fraction of coal tar through sodium hydroxide saponification and sulfuric acid acidification contains phenol, cresol and xylenol. The mixed xylenol can be obtained from the separation of crude phenol, 3,5-xylenol is removed by rectification, the remainder is rectified, and the 225-229℃ distillate is collected, cooled and crystallized, and centrifuged to obtain 3,4-xylenol . In addition, using o-xylene as raw material, the product can also be obtained through sulfonation, alkali fusion, acid precipitation, and distillation.
