【摘要】 以稀土氯化物、间氨基苯甲酸和8 羟基喹啉为原料,无水乙醇为溶剂,首次制备了8种稀土 间氨基苯甲酸 8 羟基喹啉固体配合物。经元素分析、紫外光谱、红外光谱、热重 差热分析和摩尔电导测定,确定了配合物的组成、性质和成键特征,其组成为RE(MABA)(hq)2(RE=La3+,Ce3+,Pr3+,Nd3+,Sm3+,Eu3+,Er3+,Y3+;hq=C9H6NO-;MABA-=C6H5NH2COO-)。热分析表明,配合物的热稳定性优于配体。试验了该系列配合物的抑菌活性,结果发现稀土三元配合物的抑菌效果比单独的稀土氯化物、间氨基苯甲酸、8-羟基喹啉的抑菌效果好。更多还原

【Abstract】 Eight new solid ternary complexes of rare earth with mAminobenzoic acid (MABA) and 8Hydroxyquinoline (Hhq) were synthesized in ethyl alcohol absolute. Their composition and properties are characterized by elemental analysis,molar conductance, IR, UVVIS, TGDTA. These complexes have the same composition of RE(MABA)(hq)2 (RE=La3+, Ce3+,Pr3+,Nd3+,Sm3+,Eu3+,Er3+,Y3+;hq=C9H6NO-;MABA-=C6H5NH2COO-). The fungistatic effect of these complexes are also studied.Results from fungistatic testing indicated that all these complexes have fungistatic ability on molds.更多还原
