Abstract:

A systematic verification is reported of the effect of HCN and HCl on the preparation of concentrated H2O2 from oxyhydrogen gas with Pd as the catalyst. Optimum reaction conditions and yields were the objectives. It was established that the formation of H2O2 on the catalyst was the first stage of a reaction involving the oxidation of H the second stage is the decomposition of H2O2. Certain substances act as specific or selective catalyst poisons for the second stage HCN of the H ion in diluted mineral acids serve in this capacity. HCN 10 to the -4th power normal and HCl 0.05 normal effected 75 and 56 yields, respectively. The optimum ratio of the initial substances is the stochiometric ratio for H2O2 or 11. A reduction of temperature retarded the reaction rate but increased the yield of H2O2. Acidic catalyst carriers accounted for larger yields than amphoteric carriers.
