摘要
偏硼酸钠是硼氢化钠的还原副产物。以偏硼酸钠为原料,与金属钠、石英砂进行加氢反应来制备硼氢化钠。用异丙胺对产物进行萃取提纯,制得了纯度较高、收率为47·8%的硼氢化钠产品。萃取剂回收利用率可达85%。
Sodium metaborate is a by-product from deoxidation of sodium borohydride. The sodium borohydride can be obtained by deoxidation of the aforementioned sodium metaborate as raw material in the presence of metalic sodium and quartzite. The isopropyl amine is used as extractive and purifying agent to give the final sodium borohydride with high purity and yield of 47.8%. The recovery of the extraction agent can reach 85%.
