| | 1,4-Dioxane Usage And Synthesis |
| Chemical Properties | colourless liquid | | Usage | Suitable for HPLC, spectrophotometry, environmental testing | | General Description | A clear colorless liquid with a faint ethereal odor. Flash point 55°F. Slightly denser than water and soluble in water. Vapors heavier than air. Susceptible to autooxidation to form peroxides. | | Air & Water Reactions | Highly flammable. When exposed to air 1,4-Dioxane undergoes autooxidation with formation of peroxides. In the distillation process peroxides will concentrate causing violent explosion. Water soluble. | | Reactivity Profile | 1,4-Dioxane is a flammable liquid; when exposed to air 1,4-Dioxane undergoes autooxidation with formation of peroxides. In the distillation process peroxides will concentrate causing violent explosion. The addition complex with sulfur trioxide (1:1) sometimes decomposes violently on storing at room temperature [Sisler, H. H. et al., Inorg. Synth., 1947, 2, p. 174]. Evaporation of boron trifluoride in aqueous 1,4-Dioxane with nitric acid led to an explosion upon addition of perchloric acid [MCA Guide, 1972, p. 312]. Explosive reaction with Raney nickel catalyst above 210° C {Mozingo R., Org. Synth., 1955, Coll. Vol. 3, p. 182]. | | Health Hazard | No significant irritation from brief exposure of skin; prolonged or repeated exposure may cause a rash or burn and absorption of toxic amounts leading to serious injury of liver and kidney. Chemical has poor warning properties; illness may be delayed. Moderately irritating to eyes; overexposure may cause corneal injury. |
