性质:Properties
白色粉末,midu0.66g/cm3 ,275 °C融化并分解,可溶于乙醚,四氢呋喃,脂肪胺类。有吸潮性,在干燥空气中稳定,在潮湿空气中吸潮分解,在PH>7时,能溶于水,且水溶液十分缓慢分解,在酸性介质中迅速反应。本品是一种还原剂,其还原能力介于硼氢化钠和氢化铝锂之间。
      This productiswhitepowder,density:0.66g/cm3 ,It melts and decomposes at 275°C .It can soluble in diethyl ether,THF and fatty amine.It is stable in dry air ,but it may hydrolyze in the dampair .When the PH>7,it can soluble in water slowly ,however,react with acidic medium quickly.This product is a kind of reducing agent ,and the reducing poweer of it is between those of NaBH4 and :iAIH4  .
用途:Usage
工业上用于漂白木浆和无电电镀,常被用于一些具有特殊要求的羰基还原,在有机合成中用作还原剂,能还原醛、酮和脂类。用于合成替卡格雷和地瑞那纬中间体的还原剂。
