Berzehus (19) further appHed and amplified the nomenclature introduced by Guyton de Morveau and Lavoisier. It was he who divided the elements into metalloids (nonmetals) and metals according to their electrochemical character, and the compounds of oxygen with positive elements (metals) into suboxides, oxides, and peroxides. His division of the acids according to degree of oxidation has been Httie altered. He introduced the terms anhydride and amphoteric and designated the chlorides in a manner similar to that used for the oxides. 

A refined grade of MTBE is used ia the solvents and pharmaceutical iadustries. The main advantage over other ethers is its uniquely stable stmctural framework that contains no secondary or tertiary hydrogen atoms, which makes it very resistive to oxidation and peroxide formation. In addition, its higher autoignition temperature and narrower flammabihty range also make it relatively safer to use compared to other ethers (see Table 3).

Alternative metabolic pathways involve ring-oxidation and peroxidation of arylamines. Although ring-oxidation is generally considered a detoxification reaction, an electrophilic iminoquinone (X) can be formed by a secondary oxidation of the aminophenol metabolite (18,19). Lastly, reactive imines (XI) can be formed from the primary arylamines by peroxidase-catalyzed reactions that involve free radical intermediates (reviewed in 20). 

Palladium and platinum. These are resistant to chemical attack (Pt more than Pd). Both metals dissolve in fused alkali metal oxides and peroxides. Pt is attacked, at high temperature, by molten alkali and alkaline earth halogenides and by several compounds of B, Si, Pb, P, As, Sb, Bi. Pd dissolves slowly in oxidizing acids Pt is dissolved by aqua regia. 

Why do some of the alkali metals form oxides, while others form peroxides when they burn in the air How does the stability of the alkali metal oxides and peroxides change (from lithium to cesium) when heated Why is the formation of peroxides and also of ozonides the most characteristic of the alkali metals ... 

Thermal decomposition of oxides and peroxides. High pressure oxygen can be produced by the thermal decomposition of oxides (for example, CrOs, MnjO ) and peroxides (for example, BaO2, CaO2) in a closed vessel, the pressure of which can reach up to 50 000 atm.

There are three principal categories of oxidizing agents that occur as air pollutants. These are ozone, nitrogen oxides and nitric add. and organic peroxide. Many materials that are relatively resistant to attack by the free oxygen of the air are far less resistant to attack by such oxidants and peroxides. These dissolve in the surface film and thus convert metals to their oxides which react readily even with such relatively weak acids as carbonic acid and sulfurous acid. For instance, copper tarnishes rapidly forming the oxide, which dissolves readily in dilute acids.
