| metode produksi | There are a variety of preparation methods. Propionic acid is chlorinated to 3-chloropropionic acid at about 20 °c under ultraviolet light; Very small amounts of hydroquinone may also be added to the acrylic acid and then reacted below 20 °c with dry hydrogen chloride. The final product was obtained by distillation under reduced pressure. Further, acrylonitrile was added to hot hydrochloric acid, and the reaction was conducted under reflux for 6 hours. The reactant was cooled, the resulting ammonium chloride was filtered, extracted with diethyl ether, washed with 20% ammonium chloride solution to remove hydrochloric acid, and dried to recover diethyl ether, followed by distillation under reduced pressure to obtain 3-chloropropionic acid. 3-chloropropionic acid can also be prepared by reacting acrolein with hydrogen chloride to form chloropropionaldehyde, followed by nitric acid oxidation, or by nitric acid oxidation of 3-chloro-1-propanol. |
