一般描述
锂是一种低密度碱金属,广泛用作可充电和不可充电电池的负极材料。此外,它还可用于与铝和镁铸成合金,使其结构更坚固、更轻质。
颗粒锂是一种磨成小颗粒的锂金属。锂是一种质地柔软的银白色金属,具有高反应活性和易燃性。锂的密度很低,为0.534 g/cm3,是最轻的金属之一。和其他碱金属一样,锂的熔点很低(180°C),是电和热的良导体。 颗粒锂具有高反应活性,是一种强还原剂。它可能发生点燃或爆炸,因此必须谨慎处理。锂容易与水和氧气分别反应生成氢氧化锂和氧化锂,甚至在室温下可与氮气反应生成氮化锂。通常,锂储存于氩手套箱和密封容器中,以防止其暴露于湿气、空气和氮气中。 要制成颗粒锂,首先采用碳酸锂转换工艺从锂辉石或锂云母等矿石中提取金属。将锂纯化至高纯度后,通过旋转叶片将其磨成颗粒。
应用
锂可用作:
- 合成锂铝和锂硅合金等锂基合金的前体,以用作能量转换和存储领域的负极材料。
- 熔融LiCl盐中还原氧化锆化合物的还原剂。
- 合成还原剂(1,4-双(三甲基氢化锗)-1.4-二氢吡嗪)的起始原料,以生产镍金属薄膜。

An efficient one-pot synthesis of optically active β-alkyl-substituted alcohols through a tandem copper-catalyzed asymmetric allylic alkylation (AAA) with organolithium reagents and reductive ozonolysis is presented. Furthermore, hydroboration-oxidation following the Cu-catalyzed AAA leads to the corresponding homochiral γ-alkyl-substituted alcohols.
