CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | O-chlorostyrene is a clear yellow liquid. (NTP, 1992) |
|---|---|
| Color/Form | Liquid |
| Odor | Limited evidence indicates that the odor-warning property of o-chlorostyrene does not offer adequate warning & that vapor concns must approach 400-600 ppm to discourage exposures to even unacclimated workers. |
| Boiling Point | 371.7 °F at 760 mmHg (NTP, 1992) |
| Melting Point | -81.7 °F (NTP, 1992) |
| Flash Point | 138 °F (NTP, 1992) |
| Solubility | less than 1 mg/mL at 70 °F (NTP, 1992) |
| Density | 1.1 at 68 °F (NTP, 1992) - Denser than water; will sink |
| Vapor Density | Relative vapor density (air = 1): 4.8 |
| Vapor Pressure | 0.96 mmHg at 77 °F (NIOSH, 2023) |
| LogP | 3.58 |
| Decomposition | When heated to decomposition it emits toxic fumes of /chlorides/. |
| Refractive Index | Index of refraction: 1.5649 @ 20 °C/D |
| Chemical Classes | Plastics & Rubber -> Styrenes |
