摘要
本文首次对 2 氨基 4 磺酸基 丁酸的红外光谱作了初步指认 ,并由此对其存在形式作出了判断。同时 ,合成了 2 氨基 4 磺酸基 丁酸与Na+ 、K+ 、Ca2 + 形成的络合物 ,对其红外光谱及拉曼光谱进行了分析讨论 ,并对其配位方式进行了比较。结果表明形成络合物后 ,羧基、磺酸基均参与配位 ,且破坏了原有分子间的氢键网络 ,进行分子间的重新组合。
The main IR bands of the DL Homocysteic acid was preliminary assigned.The complexes of DL Homocysteic acid with Na +,K +,Ca 2+ were synthesized.Element analysis and TGA DTA were used to conclude the compositions of these complexes.The FTIR and FT Raman spectra were studied to distinguish the different coordination structures.The bands of carboxyl,sulfonate and amino groups are all shifted.The peaks of -CH 2 also changed a lot.The results indicated that the H bonding structures among the moleculars were rearranged.The carboxyl and sulfonate groups of DLH both coordinated with the metal ions.And the coordination sturcture of CO group in the three complexes were all monodentated.
