Hydrogen peroxide safe handling

The present procedure is a specific example of the method generalized by Leonard and Johnson.8 The method employs extremely mild reaction conditions and affords high yields of sulfoxides (Note 9) free of contamination by sulfides or sulfones. Sodium periodate is easily and safely handled however, the higher cost of this reagent in comparison to certain other oxidants, e.g., hydrogen peroxide, may prohibit its use in large-scale reactions. 

From Interox Chemicals Ltd, who supply notes on the safe handling of these concentrated solutions, and advise on the use of hydrogen peroxide and peroxyacids (Section 4.2.56, p. 455). t A freshly prepared solution (5%) of sodium ascorbate should be readily available for use as an eye wash.

Concentrated peroxide may decompose violently in contact with iron, copper, chromium, and most other metals or their salts, and dust (which frequently contains rust). Absolute cleanliness, suitable equipment (PVC, butyl, or Neoprene rubber), and personal protection are essential for safe handling. During concentration under vacuum of aqueous or of aqueous-alcoholic solutions of hydrogen peroxide, violent explosions occurred when the concentration was sufficiently high (probably above 90%). Detonation of hydrogen peroxide vapor has been studied experimentally.6... 

One of the most friendly, attractive and economically justified techniques used in homogeneous systems consists of the photo-Fenton method. The photo-Fenton reagent (Fe3+/Fe27H202) is an efficient and cheap reagent, which in a very simple way produces OH radicals for wastewater treatment, due to the fact that iron is a very abundant and non-toxic element and hydrogen peroxide is easy to handle and environmentally safe. Iron in its ferrous and ferric forms acts as a photocatalyst and requires a working pH <4. At higher pH values, iron precipitates as a hydroxide. The Fenton reaction, which usually operates at or near ambient temperature and pressure ... 

Note Although Hydrogen Peroxide undergoes exothermic decomposition in the presence of dirt and other foreign materials, it is safe and stable under recommended conditions of handling and storage. Information on safe handling and use may be obtained from the supplier. 

As alluded to earlier, concentrated hydrogen peroxide, as well as not being commercially available, is also difficult to handle safely. Consequently, the ability of PBS and PCS to release oxidative species into an organic medium has made them extremely useful synthetic tools. Figure 2.10 summarizes a number of examples where PBS and PCS have been employed in this capacity. 

This is a weird situation in that we don t have any idea how the disease is contracted. If it were caught through kissing, then we all would have it, or at least most of us. To be on the safe side, don t kiss anyone with active ulcer disease and use hydrogen peroxide to wipe cooking utensils and other things that the infected person handles. 

Several oxidants have been tested over the years for epoxidation nevertheless, in recent years, hydrogen peroxide has emerged as the oxidant of choice for many transformations because it is environmentally benign, having high atom efficiency [5], and because it can be handled and stored safely, and because it produces water as the only by-product [6,7]. 

Aqueous hydrogen peroxide, as a cheap and commercially available reagent, is an ideal oxidant because it can be safely stored and handled, contains effective oxygen, and produces water as the only by-product. Due to the low standard redox potential of hydrogen peroxide in neutral or weak acidic media, it has been usually used in the presence of inorganic acids or organocatalysts. 

The reagent has been prepared in 30% yield from m-nitrobenzenesulfonyl chloride and hydrogen peroxide.1 It is relatively safe to handle and is suggested for use in the synthesis of phenols, for example ... 

The acyl derivatives of hydrogen peroxide have been widely studied and safely used even on a large scale. Nevertheless they should always be handled with care. In particular, they should not be ground, heated in a closed container, inhaled as vapour or ingested as dust. 

Peracetic acid. Peracetic acid (CH3COOOH) as formulation also contains hydrogen peroxide, and a special HAZOP pumping system has to be supplied to ensure safe handling. PAA is not affected by catalase but will be neutralised by protein rich in S-H and S-S bonds (casein).
