WebThe dissociation of Cu (OH) 2− leads to the formation of CuOH. The dissociation energy required for this reaction is 62 ± 3 kcal/mol. [3] Another method is by the double displacement of CuCl and NaOH : Notably, this method is rarely used because the CuOH produced will gradually dehydrate and eventually turn into Cu 2 O . Structure [ edit] WebDec 1, 2014 · The CuCr 2 O 4, as the best metal oxide additive, decreases the onset temperature of the AP decomposition from about 450 °C to 273 °C [8], [9], [10]. The thermal decomposition of AP catalyzed by the p-type metal oxides can be widely interpreted by the electron transfer process.
