Description

Application

• Ethylene sulfide is generally used in the preparation of organosulfur compounds, especially for mercaptoethylation of primary and secondary amines to obtain aminothiols.
• It is used in the synthesis of dendritic thioether ligands to stabilize gold nanoparticles (Au NPs).
• Chitosan can be chemically modified by treating ethylene sulfide to obtain a biopolymer for the removal of divalent cations from aqueous solutions.

Ethylene sulfide was used in the chemical modificatoion of biopolymer chitosan.
