摘　　要：双取代硅基二茂铁是用于聚硅氧烷类高分子的一种高效抗氧化剂，只要添加０．１‰～０．５‰，可以使聚硅氧烷的使用寿命提高数百倍．以二茂铁为原料，经二茂铁二钠，然后与二甲基乙氧基氯硅烷反应，使二甲基乙氧基硅基直接引入二茂铁的茂环上，二茂铁的转化率大于８０％，双（二甲基乙氧基硅基）二茂铁的产率大于６０％．1.1′Bis(ethoxydimethylsilyl) ferrocene is used widely as antioxdant of organosiloxane polymers,especially under high temperature.The procedure of published method is complex and difficult to operate.A new method using ferrocene was introduced with high yield,simple procedure and mild condition.The best synthetic condition and ratio of reactant were found by normal analytical experimental method.The product was determined by gas chromatoraphy (GC) and proto magnetic resonance spectrum (1HNMR).
