一般描述

我们致力于为您提供更环保的替代产品,以符合“绿色化学的12项原则”的一项或多项原则要求。该产品为增强型,提高了能源效率。点击此处,查看更多详情。
硼氢化钠(NaBH4)是最常用的硼氢化钠,由硼酸甲酯与氢化钠在矿物油中反应合成。它被用作生产其他金属硼氢化物的前驱体。已有关于硼氢化钠的各种定性和定量监测方法的介绍。NaBH4 在燃料电池中储存和生成氢的潜力已有相关研究。

应用

硼氢化钠可在以下应用中用作还原剂:        
  • 通过还原复合的醛和酮来制备饱和醇。        
  • 与雷尼镍(Raney nickel)联用,将芳香族硝基化合物还原为芳基胺。        
  • 在存在酸催化剂的情况下,通过还原性胺化酮和醛来合成仲胺。       
  • 通过还原环状酸酐合成δ和γ内酯。       
  • N-保护氨基酸和多肽化学选择性还原成相应的醇。
