Product Applications

It is used to make phenolic resin, medicine, insecticide, dye and explosive, etc.; 3, 5-dimethylphenol is an intermediate for preparing carbamate insecticide to kill shuttle, and can also be used to produce rubber accelerator, anti-oxidant, medicine, spices, phenolic resin, etc. are also used as cold rolling oil additives for steel rolling, which can be extended..

Production method

The mixed xylenol is rectified, the 218-222 ℃ fraction is collected, and the industrial grade 3,5-xylenol is obtained by cooling crystallization and centrifugal separation. After re-crystallization with toluene, the finished product with a purity of 98 can be obtained. The M-Xylene is sulfonated with concentrated sulfuric acid at 185℃, neutralized at 60-90 ℃, alkali fused at about 350℃, acidified by sulfuric acid, and finally distilled under reduced pressure, 3, 5-dimethylphenol can be obtained with a yield of 65.
