use | for organic synthesis, film preservative. |
Production method | It is obtained by the reaction of m-cresol and sodium hypochlorite. Under stirring, m-cresol was slowly added with 9.5%-10% sodium hypochlorite at 30-40 ℃. After adding, the temperature is maintained at 30-40 ℃, stirred for 1h, placed under sunlight for 48h, neutralized with hydrochloric acid until acidic, separated out the oil layer, washed with 1:1 volume of water, and the oil layer is distilled under reduced pressure to obtain the product. |
