CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | 3-bromopropyne appears as a colorless to light yellow liquid substance with a sharp odor. Flash point 65 °F. Denser than water and insoluble in water. Vapors are heavier than air. May be irritating to skin and eyes. Used to make other chemicals. It may decompose explosively with mild shock. |
|---|---|
| Color/Form | Liquid |
| Odor | Sharp odor |
| Boiling Point | 190 to 194 °F at 760 mmHg (EPA, 1998) |
| Melting Point | -77.9 °F (EPA, 1998) |
| Flash Point | 50 °F (EPA, 1998) |
| Solubility | Soluble in ethanol, ether, benzene, carbon tetrachloride, and chloroform |
| Density | 1.564 to 1.57 (EPA, 1998) |
| Vapor Density | 4.1 (EPA, 1998) - Heavier than air; will sink (Relative to Air) |
| Vapor Pressure | 108.0 [mmHg] |
| Henry's Law Constant | Henry's Law constant = 1.13X10-3 atm-cu m/mol at 25 °C |
| Stability/Shelf Life | When /propargyl bromide/ is ... diluted, ... with 20-30% by weight of toluene, its explosive properties are practically eliminated. |
| Autoignition Temperature | 615 °F (324 °C) |
| Decomposition | May be decomposed by mild shock. Decomposes when heated under confinement. Dilution with toluene reduces the explosive tendency of the material. |
