对一种含硅氧烷的二元氨化合物（双（４－氨基苯氧基）二甲基硅烷）的合成方法进行了研究．通过正交设计，确定了合成过程的最佳反应条件，诸如：原料配比、反应温度、反应时间、反应介质等．此外，通过红外光谱、ＤＳＣ、元素分析、核磁共振等手段对其结构进行了表征和确认． A method for synthesizing a siloxane-containing diamine compound (bis (4-aminophenoxy) dimethylsilane) was studied. Through the orthogonal design, the optimum reaction conditions of the synthesis process were determined, such as the ratio of raw materials, reaction temperature, reaction time, reaction medium and so on. In addition, its structure was characterized and confirmed by IR, DSC, elemental analysis and nuclear magnetic resonance.
