Teraethyl Lead

CAS 78-00-2  

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.
