Acrolein → 3-(Butylthio)propionaldehyde

Participants

Reaction Steps

n-Butyl mercaptan (1 mole) was stirred with 80-100 petroleum ether (150 ml) at 10° C and piperidine catalyst (0.02 gm) was added. To this, acrolein (1 mole) was added dropwise over a period of 2 hours. The reaction mixture was allowed to warm up to room temperature whereupon stirring was continued for a further 36 hours. The mixture was then distilled under reduced pressure to yield a β-n-butylmercaptopropionaldehyde fraction (0.92 mole) having a boiling range 55°-57° C at a pressure of 1-2 mm of Hg. The reaction mixture was maintained under a blanket of nitrogen at all time throughout the preparation.
