TETRAETHYLLEAD (CAS: 78-00-2)
Light yellow liquid
Make up to 100%
Tetraethyl lead is a metal organic compound, its structure is a lead atom and four ethyl molecules together.
Once widely used as additive tetraethyl lead in gasoline, in order to improve the fuel octane number, in order to prevent the stun occurs in the engine, so that they can use the higher compression ratio, in order to improve the efficiency of car engines and power. Initially using tetraethyl lead additives in the United States, compared with the first use of alcohol as additive of Europe. Leaded gasoline from its high energy content and the advantages of high storage quality, eventually became the universal use of fuel additives. One of the biggest advantages of tetraethyl lead than other antiknock agent or use high octane number gasoline mixture proportion, need only a very low concentration, to increase the octane value of the fuel. The typical preparation methods, is a fluid of ethyl (containing tetraethyl lead) untreated gasoline added to 1260 points. Other antiknock agent must, in a relatively large amounts of weight and/or are lower than those of the energy value of natural gas. High energy values of leaded gasoline will have greater fuel efficiency.
When alcohol is used as antiknock, absorbs moisture will cause the fuel and air, high humidity fuel can lead to fuel pipes, rust and corrosion. And tetraethyl lead is more soluble in gasoline, ethanol is soluble in gasoline, and solubility increases with fuel moisture. With the passage of time, the water droplets and water moisture can be formed in the fuel system of fuel pipes freeze. In addition fuel high humidity also can appear biological pollution, due to certain bacteria on the surface of the water and gasoline breeding, thus cause bacterial growth in fuel system. Tetraethyl lead toxicity, make its bactericidal properties, helps to prevent fuel pollution and caused oil degradation bacteria growth. The compounds are commonly used in automobile gasoline additives, improve the octane number, for the use of seismic explosive, so as to prolong the life of the parts. Its combustion produces solid lead oxide and lead a solid metal lead and lead oxide can rapidly accumulating inside the engine, damage to the parts in the engine.
Application:used in automobile gasoline additives, improve the octane number, for the use of seismic explosive, so as to prolong the life of the parts.
