Ethylene sulfide Chemical Properties,Uses,Production

Chemical Properties

clear colourless liquid

Uses

  • 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.

Definition

ChEBI: Thiirane is a saturated organic heteromonocyclic parent and an organosulfur heterocyclic compound.

Safety Profile

Poison by ingestion, intraperitoneal, and subcutaneous routes. Mddly toxic by inhalation. A skin, eye, and mucous membrane irritant. Questionable carcinogen with experimental tumorigenic data. Can react with oxidizing materials. When heated to decomposition, or on contact with acid or acid fumes, it emits highly toxic fumes of SOx. See also SULFIDES.
