2，3-Dichloropropionaldehyde Chemical Properties,Usage,Production
Uses
2,3-Dichloropropionaldehyde is used for undergoes condensation reactions, ene reactions, 1,2-additions; α-chloro nitrone precursor.
Preparation
2,3-Dichloropropionaldehyde is best prepared by bubbling an equimolar amount of dry Chlorine gas into neat Acrolein at 5 °C.[1] The reaction temperature thereby rises spontaneously and is kept at 40 °C until the reaction has ended. Spinning band distillation at reduced pressure (12 mmHg) affords pure 2,3- dichloropropionaldehyde as a colorless liquid in 65% yield.
storage
As 2,3-Dichloropropionaldehyde is prone to polymerization it should be used as prepared for best results. For a limited time it can be stored under nitrogen at 5 °C in tightly sealed bottles. Use in a fume hood.
