水处理剂.乙二胺四亚甲基膦酸钠 - In this paper we describe the synthesis of six derivitives of a - aminomethylphosphonic acids , three of which were synthesized for the first time , the structure of them were characterized by ir spectrum , 1h nmr and 31p nmr spectrum , the structure of proline - n - methylphosphorus acid was discussed
本文报道合成了五种-氨基膦酸衍生物，用红外光谱( ir ) ，核磁共振氢谱( ~ 1hnmr )和核磁共振磷谱( ~ ( 31 ) pnmr )表征其结构，详细讨论了脯氨酸- n -甲基膦酸的结构。 - In this paper we reported the synthesis of five zirconium proline - n - mtthy ] phosphonate - phosphate of different x value , the structure of them were characterized by ir specirum x - ray diffraction and tg - dsc thermal analysis , it has been found that the samples are highly crystallized with mono phase , the interlaycr distance of zirconium phosphonate - phosphate increase with the increment of x value , when x > l , the interlayer distance increased slightly . the ideal model of x = l of zirconium proline - n - mtthyl phosphonate - phosphate is that organic groups crosslinked with inorganic groups , take up as ababab
本文报道首次合成了不同x值x = 0 . 25 、 0 . 50 、 0 . 66 、 1 . 00 、 1 . 35的层状(脯氨酸- n -甲基膦酸-磷酸氢)锆，通过红外光谱、 x射线衍射、热重分析等手段进行结构表征，研究表明，所合成的混合磷酸锆结晶度较高，晶相比较单一，随着x值的增加，混合磷酸锆的层间距逐渐增大，当x值大于1以上时，层间距的变化较小。
