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.
