Gas-phase oxidation of 1,3-dioxolan

Abstract

The gas-phase oxidation of 1,3-dioxolan was investigated over the temperature range 240–340°C below atmospheric pressure by the static method. Explosion and cool-flame limits were determined and the kinetic constants of the slow reaction were measured. Gas chromatography was used for analysis of all products except peroxides. These were investigated by means of spectrophotometry and thin-layer chromatography. A mechanism is suggested in which 1,3-dioxolan 2-hydroperoxide and 4-hydroperoxide are degenerate branching agents below 300°C.
