Oxygen, Ozone, and Peroxides

The alcohol functional group is not rapidly attacked by oxygen or peroxides. Alcohols are attacked by ozone, but no major preparative procedures have been developed.

Alternative bleaching agents using oxygen, ozone, and peroxide have been developed. The environments produced in these stages do not appear to be as corrosive to stainless steels, but peroxide can be highly aggressive to titanium. 

The cholinesterase activity is determined in the presence of alllelochemicals-alkaloids (Fig. 4) and reactive oxygen species ozone and peroxides (Table 1). 

The material can be cured by both sulphur and peroxides, but requires protection against oxygen, ozone and UV light. 

The saturated main chain of the copolymer confers excellent resistance to oxygen, ozone and light, but means that these materials cannot be crosslinked by sulphur. Peroxides and radiation are the only methods by which crosslinking can be accomplished, and coagents are often required to achieve the required state of cure. 

Being saturated, the resistance of silicones to oxygen, ozone and UV light is excellent, but means that peroxides have to be used for vulcanisation. 

EnZone [Enzyme ozone] A pulp bleaching process using the enzyme xylanase in combination with oxygen, ozone, and hydrogen peroxide. Invented by K.-E. L. Eriksson at the University of Georgia and piloted in 1998. 

Approximate values are obtained from the potentials of the deposition of Po and P0O2. Because of the emanation of high-energy a-particles, ozone, oxygen radicals, and peroxides are formed from water, which can oxidize Po + ions.

The synthesis of 1,2,4-dioxazolines and 1,2,4-dioxazolidines is based on the use of singlet oxygen, ozone, or peroxides. Thus, photoaddition of O2 to 2-alkoxyoxazoles followed by a rearrangement leads to unstable 3-acyl-... 

Nitroso compounds are readily oxidized to the corresponding nitro compounds by peroxides, peroxy acids, oxygen, ozone and dinitrogen tetroxide. ... 

Oxygen, ozone and hydrogen peroxide do not oxidise carbon monoxide at ordinary temperatures, but in presence of catalysts, as, for instance, " Hopcalite (a mixture of 60% MnOg and 40% CuO), even atmospheric oxygen will convert carbon monoxide to carbon dioxide. Because of this behaviour, Hopcalite is employed in filters for defence against carbon monoxide. 

Oxygen, chlorine, ozone, and peroxide compounds are examples of oxidizing agents.
