CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Divinyl benzene appears as a water-white to straw colored liquid. Slightly less dense than water and insoluble in water. Vapors may be toxic. Used in making rubber. |
|---|---|
| Color/Form | Pale, straw-colored liquid. |
| Boiling Point | 383 °F at 760 mmHg (NTP, 1992) |
| Melting Point | -125 °F (NTP, 1992) |
| Flash Point | 143 °F (NTP, 1992) |
| Solubility | less than 1 mg/mL at 64 °F (NTP, 1992) |
| Density | 0.93 (NIOSH, 2023) - Less dense than water; will float |
| Vapor Density | Relative vapor density (air = 1): 4.48 |
| Vapor Pressure | 0.7 mmHg (NIOSH, 2023) |
| LogP | log Kow = 3.8 /Estimated/ |
| Autoignition Temperature | 500 °C |
| Decomposition | When heated to decomposition it emits acrid smoke and irritating fumes |
| Polymerization | Hazardous polymerization may occur. ... Usually contains inhibitors to prevent polymerization. Uninhibited monomer vapor may form polymer in vents and other confined spaces. |
| Odor Threshold | As with other styrene monomers, the odor can be detected by humans at levels below dangerous concn, ie, 10-60 ppm. |
| Kovats Retention Index | 1102 |
| Other Experimental Properties | Commercial product contains all three isomers, but the m-isomer predominates. Usually contains an inhibitor to prevent polymerization. |
| Chemical Classes | Plastics & Rubber -> Styrenes |
