Thermal Stability of 1,4-Dioxane at Sub- and Supercritical Temperatures

Thermal stability of 1,4-dioxane below and above its critical temperature (at 300— 500 °C) and at different fluid densities is studied. In the temperature range of 300— 350 °C dioxane is thermally stable during 80—100 minutes; at higher temperatures during the same time the uncontrolled pressure growth starts due to the thermal cracking of dioxane. The analysis of liquid and gas phases after the dioxane thermal treatment shows the formation of a wide range of products.

Key words: 1,4-dioxane, thermal stability
