Participants

Reaction Steps

Into a 100 ml reaction flask equipped with thermometer, reflux condenser and magnetic stirring bar and hot plate equipped with magnetic stirring apparatus is placed 0.2 grams of para-toluenesulfonic acid, 5 ml cyclohexane and 7.6 grams (0.1 mole) of n-propyl mercaptan. With stirring over a period of 25 minutes, 6 grams (0.05 moles) of phenyl acetaldehyde is added to the reaction mass. The reaction mass is then heated to reflux and refluxed for a period of 8.5 hours. During the refluxing period, water of reaction is removed. At the end of the refluxing period, the reaction mass is cooled to room temperature and transferred to a separatory funnel. The reaction mass is washed with one 50 ml portion of saturated aqueous sodium chloride solution, and then dried over anhydrous sodium sulfate and filtered. The filtrate is distilled on a Microvigreux column yielding the following five fractions:
