| Production method | It is obtained by chlorination of acetyl n-propanol. Add hydrochloric acid and acetyl n-propanol to the reaction pot and heat, steam out hydrochloric acid and 5-chloro-2-pentanone, let it stand and layer after cooling, and return the lower hydrochloric acid to the reaction pot until there is no 5-chloro-2-pentanone so far. Another operation method is to add sulfuric acid and acetyl n-propanol to hydrochloric acid and sodium chloride in proportion, and chlorinate at 84-88 ℃ for 15min. |
