Description

General description

Diethyl sulfide forms 1:1 charge transfer complex with iodine. It undergoes photocatalytic degradation over TiO₂ . It is commonly used as solvent for anhydrous mineral salts and in plating baths for coating metals with gold or silver.

Application

Diethyl sulfide was used to assess the quantification procedure for nine volatile sulfur compounds in complex gaseous samples by solid-phase microextraction.
