Abstract
It has been shown that, at a temperature of 75°C, 1,3,5-trioxane obtained by the liquid-phase method in the presence of a homogeneous catalyst partially decomposes with the formation of free formaldehyde, paraformaldehyde, and formic acid. A number of stabilizers for the thermal-oxidative degradation of 1,3,5-trioxane have been proposed and their effectiveness has been compared. The most effective additives were selected and their concentrations were determined, which provide the minimum amount of by-product formation under the indicated conditions.
