Use | 3-methyl-4-isopropylphenol is an effective reagent for cross-coupling reactions. Used as an antiseptic and fungicide for cream cosmetics. |
Production method | Dissolve m-cresol and chloroisopropane in trichloroethylene, use anhydrous aluminum trichloride as a catalyst, and react at 10-15 ℃, Then hydrolyze and distill to obtain 3-methyl -4-isopropyl phenol. In addition, m-cresol reacts with isopropanol at 100-120°C, and the finished product can also be produced with sulfuric acid or phosphoric acid as a catalyst. |
