Self accelerating decomposition temperature values

Though regarded as one of the more stable peroxides, it becomes shock-sensitive on heating, and self-accelerating decomposition sets in at 49° C [1]. One of the recently calculated values of 46 and 42°C for induction periods of 7 and 60 days, respectively, for critical ignition temperatures is closely similar to that (4577 days) previously recorded. Autocatalytic combustion of the polymerisation initiator is exhibited. Although not ordinarily shock sensitive, it responds to a detonator [2],... [Pg.1287]

We see from Eq. (28) that, once the size of a solid chemical of the TD type, placed in the atmosphere under isothermal conditions, is specified in other words, once the values of A H, Aq and E of the exothermic decomposition reaction, in the early stages of the self-heating process, of the solid chemical as well as the values of A and r of the solid chemical are fixed, respectively, the value of S increases with increasing the atmospheric temperature, Ta- There is, however, the upper limit value, or the critical value, of S, i.e., S which S is able to take for a shape of the solid chemical, because there is also the upper limit atmospheric temperature, or the critical temperature, 7)., above which the stationary gradient distribution of temperature in the self-heating solid chemical ceases to be possible, with the result that the temperature of the solid chemical continues to increase acceleratedly to cause the ultimate thermal explosion of the solid chemical. [Pg.12]
