#Hydrogen dioxide series
The large amounts of hydrogen peroxide used in industry are prepared in a complex series of reactions that begins with any one of a family of compounds known as the alkyl anthrahydroquinones, such as ethyl anthrahydroquinone. Hydrogen peroxide is also present in plant and animal cells as the byproduct of metabolic reactions that occur in those cells. It is formed when atmospheric oxygen reacts with water to form H 2O 2. Hydrogen peroxide occurs in very small amounts in nature. Today, industrial processes make about 500 million kilograms (1 billion pounds) of hydrogen peroxide annually for use in a wide variety of applications ranging from whitening of teeth to propelling rockets. It was first used commercially in the 1800s, primarily to bleach hats. Hydrogen peroxide was discovered in 1818 by French chemist Louis Jacques Thénard (1777–1857).
Hydrogen dioxide hydroperoxide peroxide FORMULA: To prevent decomposition, small amounts of inhibitors, such as acetanilide or sodium stannate are added to pure hydrogen peroxide and hydrogen peroxide solutions. Even small amounts of impurities (such as iron or copper), however, act as catalysts that increase its tendency to decompose, sometimes violently, into water and nascent oxygen (O). When absolutely pure, the compound is quite stable.

Mixtures of aqueous hydrogen peroxide with 1-phenyl-2-methyl propyl alcohol tend to explode if acidified with 70% sulfuric acid. Concentration of solutions of hydrogen peroxide under vacuum led to violent explosions when the concentration was sufficiently high (>90%). Solutions containing over 30% hydrogen peroxide can detonate when mixed with organic solvents (such as acetone, ethanol, glycerol) the violence of the explosion increases with increasing concentration of the hydrogen peroxide. Contact with combustible materials may result in their spontaneous ignition. Stabilization operates against such reactions, but does not eliminate their possibility. May decompose violently in contact with iron, copper, chromium, and most other metals or their salts, which act as catalysts for this reaction, and with ordinary dust (which frequently contain rust, also a catalyst for this reaction). Will react or decompose violently and exothermically with readily oxidizable materials or alkaline substances. HYDROGEN PEROXIDE, AQUEOUS SOLUTION, STABILIZED, WITH MORE THAN 60% HYDROGEN PEROXIDE is a powerful oxidizing agent.
