摘　　要：采用常压制备色谱分离了六苄基六氮杂异伍兹烷(HBIW)中提取的杂质,重结晶得到其中一种主要的杂质晶体;应用FT-IR1、H-NMR、ESI-MS、元素分析鉴定了该杂质的结构,研究了它的形成途径及对氢解反应催化剂钯的影响。结果表明HBIW中的主要杂质是草酰二苄胺(Bn—NHCO-)-2,它主要由醛胺缩合中间体C6H5CH2NHCH(OH)CH(OH)NHCH2C6H5在空气中氧化而生成,氢解反应中它会危害到催化剂钯的活性。The impurities in hexabenzylhexaazaisowurtzitane （HBIW） were isolated by preparativechromatograph, and the crystal of the main impurity in HBIW was obtained by recrystal technic. Thestructure of the impurity was studied with FT-IR, 1H-NMR, ES1-MS, element analysis. The formingof the impurity and its effect on the catalyst Pd in the hydrogenolysis are discussed. The results show that the main impurity in HBIW is oxalic dibenzylamine （Bn-NHCO-）-2, which is formed from C6H5CH2NHCH（OH）CH（OH）NHCH2C6H5 oxidated by the oxygen in the air.
