| Brandgefahren | Excerpt from ERG Guide 137 [Substances - Water-Reactive - Corrosive]:EXCEPT FOR ACETIC ANHYDRIDE (UN1715), THAT IS FLAMMABLE, some of these materials may burn, but none ignite readily. May ignite combustibles (wood, paper, oil, clothing, etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Flammable/toxic gases may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. Substance may be transported in a molten form. (ERG, 2024) |
Anwendungen & Verwendung
Verwenden
Disulfur dichloride is used as Intermediate and chlorinating agent in the manufacture of organic chemicals, sulfur dyes, insecticides, synthetic rubbers; in cold vulcanization of rubber; as polymerization catalyst for vegetable oils; for hardening soft woods. The chemical fiber industry is used as a finishing agent for the manufacture of fabrics. The metallurgical industry is used as an extraction agent for precious and rare metals such as gold and silver.
