Oxidizing agents green

Isopropylbenzene is made from benzene and propene, both of which are readily available petrochemicals, O2 is the ultimate green oxidizing agent, and the waste products are either benign (water) or easiiy managed (sulfuric acid). 

As previously shown, the marriage of green oxidant agents, like H2O2, and well-developed catalysts, such as TS-1, is able to drive strong improvement in industrial chemistry. 

Fusion of MnOa with an alkali metal hydroxide and an oxidizing agent such as KNO3 produces very dark-green manganate(VI) salts (manganates) which are stable in strongly alkaline solution but which disproportionate readily in neutral or acid solution (see Fig. 24.1) ... 

Compounds having the dibenzo-p-dioxin nucleus give a blue to blue- green color when dissolved in concentrated sulfuric acid with oxidizing agents, such as H .02 and KNO (I). 

Many metals are fairly easily oxidized. The atmosphere contains a powerful oxidizing agent oxygen. Because metals are constantly in contact with oxygen, they are vulnerable to corrosion. In fact, the term corrosion is sometimes defined as the oxidation of metals exposed to the environment. In North America, about 20% to 25% of iron and steel production is used to replace objects that have been damaged or destroyed by corrosion. However, not all corrosion is harmful. For example, the green layer formed by the corrosion of a copper roof is considered attractive by many people. 

Titrate 300 mL 0.1 M FeQ2 solution to pH 8 with 5 M NaOH with stirring. Add 40 mL 30% H2O2 in one lot. As the reaction is violent, it should be carried out in a 2 L beaker in a fume hood. Upon addition of the oxidizing agent, the green suspension rapidly turns reddish brown. Centrifuge, wash and dry the product at 40 °C.
