仲丁基膦酸-2-丁基辛酯与希土固体配合物的研究

STUDY ON SEC. BUTYL PHOSPHONIC ACID 2 BUTYLOCTYL ESTER COMPLEXES WITH RARE EARTHS

合成了仲丁基膦酸－２－丁基辛酯（ＨＢＯ／ＢＰ）与希土（Ⅲ）（Ｌｎ＝Ｌａ，Ｇｄ，Ｈｏ，Ｙ，Ｅｒ，Ｙｂ）新的固体配合物，其组成为Ｌｎ（ＢＯ／ＢＰ）３，对配合物的性质进行了表征。热分析表明，在空气中，热分解分两步完成，热分解产物是Ｌｎ２Ｐ４Ｏ１３。测定了配合物的红外光谱，对其主要吸收谱带进行了归属，配合物中Ｌｎ－Ｏ键具有较高的离子特性。

The new solid complexes of sec. butyl phosphonic acid 2 butyloctyl ester (HBO/BP) with rare earths (Ln=La, Gd, Ho, Y, Er, Yb) were synthesized and their composition was identified to be Ln(BO/BP) 3. The infrared spectra were measured for Ln(BO/BP) 3 and principal absorption bands were assigned. The results showed that the Ln O bands of Ln(BO/BP) 3 have higher ionic characteristic. The thermal analysis of the complexes were studied in air. The thermal decomposition residues of the complexes were verified by element analysis, infrared spectra and x ray diffraction to be Ln 2P 4O 13 in air.
