氢化铝锂新合成方法的研究

A NEW ROUTE TO LITHIUM ALUMINIUN HYDRIDE(LiAlH4)

在略高溫度下,通过氯化锂和金属钠在氫气氛中的反应,得到了氢化锂和氯化钠的混合物。用通常的Schlesinger法将得到的混合物用于合成氢化铝锂。反应的副产物是氯化锂和氯化钠的混合物,可用不同方法将其分离,所得氯化锂用于再循环。

A mixture(LiH+NaCl)of lithium hydride and sodium chloride was produced by the reaction of lithium chloride and metallic sodium in an atmosphere of hydrogen at slightly elevated temperature and used to synthesize lithium aluminium hydride by the usual Schlesinger method.The by-product of the reaction was a mixture of lithium chloride and sodium chloride,which was separated by various methods and the lithium chloride obtained was recycled.
