Synthesis of dibutyl sulfide

Preparation of dibutyl sulfide

Preparation of dibutyl sulfide

Preparation of dibutyl sulfide

1.5 mole of sodium sulfide nonahydrate is dissolved in 250 ml of water and 50 ml of methanol in a three-necked flask fitted with a reflux condenser, dropping funnel, and stirrer. Then 2 moles of the appropriate butyl bromide is added and the mixture is boiled under reflux with very vigorous stirring for 5 hours. After cooling, the reaction mixture is extracted with ether, the ethereal layer is separated off, the aqueous solution is additionally extracted several times with ether several times, and the combined organic phases are washed with 10% caustic sodium carbonate and finally with water. After drying with calcium chloride, dibutyl sulfide is distilled yielding 70%, b.p. 75° C/10mm, nD20 1.4529.
