Procedure

Lauryl mercaptan (1 mole) was stirred with diethyl ether (150 ml) at 10° C and to this was added dropwise crotonaldehyde (1 mole) over a period of 2 hours. After the completion of the addition, the reaction mixture was warmed to room temperature and reacted for a further 22 hours. The reaction mixture was then distilled to give a laurylmercaptobutyraldehyde product fraction (0.90 moles) of boiling range 147°-150° C at 1.5 mm Hg. The reaction mixture was maintained under nitrogen at all times.
