Diethyl sulfide is a clear flammable chemical compound with a pungent garlic-like odor. It has the chemical formula C4H10S. It is prepared by treating ethanol with concentrated sulfuric acid, partially neutralizing the new solution with sodium carbonate, then distilling the resulting sodium ethyl sulfate in a solution containing potassium sulfide.[1]
Diethly sulfide is used as a solvent for anhydrous minerals and in plating baths for gold and silver.[1]
