论文编号:HG110  论文字数:12652,页数:29

摘 要：本论文合成了几种单金属醇盐和双金属醇盐。对于单金属醇盐，设计实验利用通氨气提供的碱性环境，使乙醇和氯化锶反应生成乙醇锶；对于双金属醇盐，设计实验由丙三醇作为基本原料合成丙三醇乙醚，将四氯化钛与氯化锶在有机溶剂中混合，然后在氨气提供的碱性环境下滴加丙三醇乙醚来合成含有醚键的钛、锶双金属醇盐。并使用沸点较高的二甲苯作为溶剂以加快反应速率。对产物进行红外表征,在乙醇锶的红外光谱中发现在673.03cm-1出现了一个很强的吸收峰，根据文献可知其为Sr-O的特征吸收峰；在双金属醇盐中发现在693.71cm-1和536.53 cm-1处有两个较强的吸收峰,由文献可知他们为Ti-O键和Sr-O键的伸缩振动吸收峰。

Study on Synthesis and characterize of organic metal alkoxides

Abstract: Several single metal alkoxides and double metal alkoxides are synthesized in this paper. For single metal alkoxides, the reaction  between ethanol and strontium chloride under the alkaline environment by providing ammonia gas, producing strontium ethanol; for double metal alkoxides, the synthesis process of the double metal alkoxides as follows: glycerol as the basic raw material to produce glycerol ether first, and then mixed titanium tetrachloride and strontium chloride together in an organic solvent under alkaline environment by providing ammonia gas, at last, dropping glycerol ether into the mixture to produce the target product. The reaction rate is accelerated by using high boiling point solvents xylene as organic solvent. The product is characterized by IR spectrum and a strong absorption peak was found at 673.03 cm-1 which is the characteristic absorption peak of Sr-O bond according to the literature; and two strong absorption peaks are found at 693.71 cm-1 and 536.53 cm-1, they are the characteristic absorption peak of Sr-O bond and Ti-O bond respectively。

 Key words:  Metal alkoxides ;  Ferroelectric materials; Glycerol.
