CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Butyryl chloride appears as a clear colorless liquid with a sharp odor. Slightly denser than water. Flash point near 20 °F. Severely irritates skin, eyes, and mucous membranes. Used to make other chemicals. |
|---|---|
| Color/Form | Colorless liquid |
| Odor | Pungent acid chloride odor |
| Boiling Point | 216 °F at 760 mmHg (NTP, 1992) |
| Melting Point | -128 °F (NTP, 1992) |
| Flash Point | 71 °F (NTP, 1992) |
| Solubility | Reaction (NTP, 1992) |
| Density | 1.0277 at 68 °F (USCG, 1999) - Denser than water; will sink |
| Vapor Density | 3.67 (vapor specific gravity) |
| Vapor Pressure | 18.8 mmHg at 28 °F ; 41.7 mmHg at 77 °F; 95.2 mmHg at 108 °F (NTP, 1992) |
| Stability/Shelf Life | Stable under recommended storage conditions. |
| Decomposition | Dissolves slowly with decomposition in water, alcohol. |
| Corrosivity | Corrosive to metals |
| Refractive Index | Index of refraction: 1.4121 at 20 °C |
| Kovats Retention Index | 705 |
| Other Experimental Properties | Fumes in air. Decomposes exothermically in water to give corrosive hydrochloric acid. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Chloride gas will be created in 0.47 minutes. |
