Thermal Stability and Kinetics of Decomposition of Hydrogen Polyoxides H2O3 and H2O4 in Peroxy Radical Condensates
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 sol...

| description | 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
