摘　　要：用干灰化法将三乙酰氧基硼氢化钠中的有机硼转化为硼酸盐,在适宜的pH条件下,将硼酸盐转化为硼酸,用甘露醇强化硼酸的酸性,酸碱滴定法确定硼酸的含量,计算出三乙酰氧基硼氢化钠的含量.此方法的精密度、准确度良好.标准偏差为0.39%,相对标准偏差为0.39%,回收率为100%.The organic boron in sodium thriacetory borohydride was converted into borate through dry cinefaction.Then borate was converted into boric acid on condition of suitable PH. At last, the acidity of the boric acid was enhanced with mannite, the content of the boric acid was determined through acid-base titrimetric and the content of the sodium thriacetory borohydride was computed. Precision and accuracy of this method is good. Standard deviation is 0.39%. Relative standard deviation is 0.39%. Percent recovery is 100.10%.
