Use | organic synthesis intermediates. |
production method | chloroprene and 37% hydrochloric acid were added into a pressure kettle, and appropriate amounts of cuprous chloride and ammonium chloride were added, followed by reaction at room temperature for 12 hours. After the reactant was cooled, the organic layer was separated and distilled under reduced pressure to collect a fraction at 35-40 ° C. (2.66kPa) to give 1, 3-dichloro-2-butene. Yield 58%. |
