CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Acetylene tetrabromide appears as a yellowish liquid with a pungent odor, much like camphor. Irritates skin. Ingestion or inhalation may produce irritation or a narcotic effect. Chronic exposure may damage liver. Noncombustible, but decomposes at 374 °F, releasing flammable and toxic fumes. Much denser than water. Used as a solvent for fats, oils and waxes. |
