| 1,4-Dioxane Chemical Properties | |
| Melting point | 12 °C |
| Boiling point | 101 °C |
| density | 1.034 g/mL at 25 °C(lit.) |
| vapor density | 3 (vs air) |
| vapor pressure | 27 mm Hg ( 20 °C) |
| refractive index | n20/D 1.422(lit.) |
| Fp | 54 °F |
| storage temp. | room temp |
| solubility | Soluble in acetone, alcohol, benzene, and ether (Weast, 1986). Miscible with most organic solvents (Huntress and Mulliken, 1941) including 2-methylpropanol, toluene, cychexanone, and cyclopentanone. |
| form | Solution |
| color | APHA: ≤20 |
| Odor | Mild ether-like odor detectable at 0.8 to 172 ppm (mean = 12 ppm) |
| PH | 6-8 (500g/l, H2O, 20℃) |
| explosive limit | 1.7-25.2%(V) |
| Water Solubility | SOLUBLE |
| Sensitive | Hygroscopic |
