Production method of Organic Intermediate 2-tert-Butyl-4-methylphenol

The production method is obtained by the action of p-cresol and isobutylene under the catalysis of 732# strong acidic ion exchange resin. The above reaction was carried out at about 60 ° C. After completion of the reaction, the catalyst was filtered off. The filtrate was added to a methanol caustic soda solution, and the reaction by-product 2,6-di-tert-butyl-p-cresol was precipitated, filtered, and recrystallized from ethanol to obtain a 264 antioxidant as a by-product. The filtered filtrate is neutralized with sulfuric acid, distilled, washed with water, distilled under reduced pressure, crystallized, and filtered to obtain a finished product.
