摘要
以碱土金属钙醇盐为烷氧基提供者,与无水稀土乙酸盐(乙酸镧、乙酸镨、乙酸钕、乙酸钐)在芳香族类溶剂体系中60℃回流加热反应6h～8h,合成出稀土金属(La、Pr、Nd、Sm)甲醇盐。样品红外光谱表明,在1035cm-1左右出现了甲氧基与稀土元素键合的C-O-Ln键的特征吸收峰,紫外-可见谱中出现的三价稀土离子的特征吸收峰,进一步证实了样品为稀土甲醇盐。
The rare earth(La, Pr, Nd, Sm) methoxides were synthesized in the condition of alkaline earth alkoxides as the providers of alkoxy, anhydrous rare earth acetates as the raw materials. IR spectra results show that the characteristic absorb band of the bond C-O-Ln appears at around 1035cm^(-1). The characteristic absorb bands of rare earth ions arisen in the UV-Vis spectra confirm farther the samples are rare earth methoxides.
