production method | synthesis of 1.3-methyl -6-tert-butyl phenol, aluminum trichloride and concentrated sulfuric acid were added to the reaction kettle, and heated to 310-320 ° C. Under stirring to carry out alkylation reaction. After completion of the reaction, the reaction product was neutralized and distilled to give 3-methyl-6-tert-butylphenol. 2.3-methyl -6-tert-butylphenol is reacted with sulfur dichloride at a temperature of 45-50 °c. After the end of the reaction with petroleum ether dissolved and cooled crystals, and then filtered, washed, dried, that is to obtain the finished product. |
