The kinetics and mechanism of the gas-phase thermal decomposition of 2-methyl-1,3-dioxolane has been studied in a static system. The infrared spectra of solid, liquid and gaseous 2-methyl-1,3-dioxolane has been studied. Low-temperature ozonation of 2-methyl-1,3-dioxolane in acetone-d6, methyl acetate and tert-butyl methyl ether has been reported.
