- Аннотация: Experimental studies are performed of the kinetics of decomposition of peroxy radical condensates (PRC) under conditions of a rise in temperature according to a linear law and control during the process by measuring the pressure of gaseous products in a constant volume system. An original way of solving the inverse problem of non-isothermal kinetics is proposed that does not require transformation of experimental dependence P(T). Four stages of gas evolution during the decomposition of PRC are discovered, and their temperature intervals and kinetic characteristics are determined. The Raman spectra of peroxy radical condensates (PRC) are analyzed at different temperatures. Based on the results, it is proposed that the stages of decomposition be attributed to the decomposition reactions of hydrogen tetroxide H2O4 and trioxide H2O3. Temperature intervals of stability and kinetic characteristics of decomposition reactions of polyoxides H2O4 and H2O3 in the composition of PRC are established. The quantitative composition of freshly prepared condensates is determined.
