Results and discussion
Applicant's summary and conclusion
- Executive summary:
The following text is copied from Goor et al. (1989), page 461:
"The decomposition of hydrogen peroxide caused by catalytic impurities and the associated release of heat have been described in Chapters 2 and 3. Great care must be taken in production, storage, and transportation to prevent these impurities from entering the hydrogen peroxide solution and to ensure that hydrogen peroxide is put only into perfectly clean containers. Because commercial hydrogen peroxide always contains small quantities of catalytic impurities, the stabilization of peroxide solutions is extremely important. The stabilizing effects of inorganic and organic compounds are described in detail in [3].
Sodium pyrophosphate [7722 -88 -5] and sodium stannate [12058 -66 -1] are the preferred stabilizers and are added separately or together [112], [113]. Organic compounds are not stable enough for use with concentrated hydrogen peroxide; they are preferred for dilute solutions [114], [115].
Aluminium (99.5 %), aluminium-magnesium alloys, or stainless steels are good construction materials. Because of their corrosion resistance, polyethylene containers and storage tanks are preferred for hydrogen peroxide concentrations up to 50 wt %. Before metallic tanks and containers can be used, their surfaces must be passivated. Iron particles may become attached to the surface during the rolling of aluminium, and they must be removed. Aluminium is, therefore, treated with dilute sodium hydroxide, safety precautions must be taken to avoid detonating gas atmosphere. It is extremely important to ensure that no hydrogen peroxide is trapped, e.g. between closed valves. If decomposition occurs, extremely high pressures result which lead to very serious explosions."
