Preparation of diisopentyl sulfide

Preparation of diisopentyl sulfide

Preparation of diisopentyl sulfide

98.9 g. of isoamyl bromide are added slowly to a solution of 116.7 g. of sodium sulfide nonahydrate in 500 ml. of ethanol. The mixture is heated to reflux for 2 hours, and after it is cooled to room temperature the precipitated oil is removed. The remaining liquid is poured into 750 ml. of 25% aqueous sodium chloride solution, and the precipitated oil is separated. The combined oil fractions are dried over anhydrous sodium sulfate and distilled twice through a 36-cm. Hempel fractionating column filled with glass beads. The yield based on bromide is 59 %, and the product boils at 214°.
