摘　　要：采用多种核磁共振技术测定了一种重要有机膦酸２－磷酸基丁烷－１，２，４三核酸（ＰＢＴＣ）的分子结构，发现其分子中至少存在着２对不等价同碳质子；测取了分子中各磁性核之间的偶合常数，并依靠这些数据解释了有关谱峰的形状特点；归属了ＰＢＴＣ工业产品中的杂质峰，并解释了ＰＢＴＣ各谱峰随浓度改变而发生位移的原因。The molecular structure of PBTC (2-phosphonobutane- 1, 2, 4-tricarhoxylic acid), was deter- mined by using diverse NMR techniques. It has been found that there are at least two pairs of unequal protons connected with the same carbon atom in PBTC molecule. The coupling constants between mag- netical nuclei were measured, by which the related peaks' shape was explained. The peaks of impurities in industrial PBTC product were assigned and the reason why the peaks of PBTC shift with its concentration change was given.
