Diethyl disulfide Chemical Properties, Uses, Production

Chemical Properties

Colorless to yellowish liquid; onion/cabbage odor

Chemical Properties

clear colorless to light yellow liquid

Uses

Diethyl sulfide is used as a solvent for anhydrous minerals and in plating baths for gold and silver

Definition

ChEBI: Diethyl disulfide is an organic disulfide.

Purification Methods

Dry the disulfide over silica gel or MgSO4 and distil it under reduced pressure (optionally from CaCl2). [Beilstein 1 H 347, 1 I 173, 1 II 345, 1 III 1377, 1 IV 1379.]
