四乙基铅(tetraethyl lead)是有机金属化合物的一种,其结构是一个铅原子与4个乙基分子连在一起组成的,是一种略带水果香甜味的无色透明油状液体,约含铅64%。常温下极易挥发,即使0℃时也可产生大量蒸气,有高度脂溶性,不溶于水,易溶于有机溶剂。四乙基铅曾广泛用作汽油添加剂,以提高燃料的辛烷值,防止发动机内发生震爆,从而能够使用更高的压缩比率,藉以提高发动机效率和功率。到了20世纪70年代,随着 Tetethyl lead (tetraethyl lead) is a kind of organometallic compound, the structure is a lead atom and four ethyl molecules together, is a slightly sweet and fruity colorless liquid with a clear oily, about Lead 64%. Very volatile at room temperature, even 0 ℃ can also produce a lot of steam, highly fat-soluble, insoluble in water, soluble in organic solvents. Tetraethyl lead has been widely used as a gasoline additive to increase the octane number of the fuel and prevent shocks in the engine, thereby enabling a higher compression ratio to be used to increase engine efficiency and power. By the 1970s, with
