Ferrocene, also known as the two cyclopentadienyl iron, cyclopentadienyl iron insoluble in water, soluble in benzene, ether, gasoline, diesel and other organic solvents. With acid, alkali, ultraviolet light does not occur, chemical stability, does not decompose within 400 degrees. Presents its molecular polarity having high thermal stability, chemical stability and radiation resistance, which has a wide range of applications in industry, agriculture, medicine, aerospace, energy saving and environmental protection industries. Ferrocene can be used as rocket fuel additives, antiknock agent and rubber and silicone resin curing agent gasoline, but also for ultraviolet absorber. Vinyl ferrocene derivatives can happen ethylenic polymerization to obtain a carbon chain skeleton of metal-containing polymers can be used for spacecraft outer coating. Smoke combustion effect of ferrocene found earlier, no litigation is added to the solid fuel, liquid fuel or gas fuel can exert this effect, especially for large hydrocarbons produced smoke when burned, its effect is more significant. Add a very good role in the earthquake in gasoline, but due to the influence of the iron oxide deposition spark plug ignition is limited, therefore, it was ranked using a mixture of iron deposition in order to reduce the phenomenon of iron. Ferrocene added to the kerosene or diesel oil, since the engine without ignition device, so fewer adverse effects, in addition to combustion in the combustion smoke outside, as well as to promote its role in the carbon monoxide into carbon dioxide compared.
