摘 要：本論文主要介紹了幾種金屬醇鹽的制備方法，設計了合成單金屬醇鹽和雙金屬醇鹽的路線。對于單金屬醇鹽，在通氨氣的條件下，使乙醇和氯化鍶反應，生成乙醇鍶，在此過程中，氨氣的主要作用是提供堿性條件。對于雙金屬醇鹽，其合成過程為首先在丙三醇的一個端羥基上加鈉，利用威廉森合成法，使丙三醇鈉與溴乙烷反應生成混醚；再和氯化鈦與氯化鍶混合物反應，通氨氣，在丙三醇的另外兩個羥基上加上金屬鈦和鍶。為了表征產物的結構，文章對純化后金屬醇鹽做了紅外檢測，發現單金屬醇鹽產物中含有O-Sr,雙金屬醇鹽產物中含有O-Ti和O-Sr。為了便于蒸餾，分離產物，可使用苯作為有機溶劑。文中合成的金屬醇鹽在鐵電材料領域有廣闊的應用前景。

Abstract: This article mainly introduces several metal alkoxides preparation methods， designs synthesis of single metal alkoxides and double metal alkoxides. To single metal alkoxides, we use Ammonia Synthesis reaction, thus under the condition of ammonia, make ethanol and strontium chloride reaction to produce ethanol strontium. In this process ,the primary role of ammonia is providing basic conditions. To double metal alkoxides, through the use of Williamson Synthesis, we first add sodium to glycerol, make it react with dibromethane to produce mixed ether; then under the condition of ammonia ,make the mixed ether reacts with chloride titanium and chloride strontium to add titanium and strontium to glycerol. To characterize the product structure, we did infrared detection to the purified metal alkoxides, then we noticed single metal alkoxides containing O-Sr and double metal alkoxides containing O-Ti and O-Sr. In order to facilitate the distillation and separate the production, benzene can be used as organic solvent. The synthesis of metal alkoxides that the text introduced have a broad application prospects in the field of ferroelectric material.Kyewords:Glycerin; Electric iron; Metal alkoxides
