仲丁基锂具有非常强的碱性,在有机合成中极为有用。人们发现,在芳香族基质的邻位金属化中,SBL 显得尤其实用。SBL 还是苯乙烯与共轭二烯阴离子聚合反应的一种非常有效的引发剂。尤其是 SBL 可以促进 SBR 溶液和苯乙烯热塑性弹性体 (TPE) 的合成。参考资料:“有机锂化合物的化学性质”(The Chemistry of Organolithium Compounds),编者 Zvi Rappoport 和 Ilan Marek,Wiley,2004 年,英国西萨塞克斯郡。

LiOMe 是一种弱碱,主要用于有机合成,最常用于酯交换反应中。这种试剂目前是以 LiOMe 甲醇溶液(2.2 摩尔/升)的形式提供,因此非常容易从运输容器转移到储存容器或反应器中。如果接触到水分,它将转化为甲醇和氢氧化锂,从而导致溶液变浑浊。有关主要参考资料,请咨询 J. Mater。Res.1999 年,14,1510。
Appearance: An odorless white, free-flowing powder Application: A free-flowing, odorless white powder with guaranteed 99.5 wt. % purity and a relatively fine particle size. Battery Grade product is a superior purity grade for use as a precursor in making critical battery materials.
Appearance: Free-flowing white crystals.* * Occasional dark particles may be visible and scattered in the product. The particles have no detectable effect on product purity and will not be cause for rejection. Application: Molten salt chemistry and metallurgy, brazing fluxes, catalyst for organic oxidation reactions, electrolyte in dry cells used in low temperatures, and stabilizer in textile fiber spinning solutions. Solubilizer for polyamides and cellulose when used with amide solvents, chlorinating agent for steroid agents. Desiccant for drying applications, tracer in wastewater.
