摘　　要：以双核二茂铁(2,2-双乙基二茂铁丙烷)为原料,通过傅克酰基化将4-氯丁酰氯接枝在双核2,2-双-乙基二茂铁丙烷的一端,酰基还原后与二甲基一氯硅烷偶联,制备出有机硅氢双核二茂铁,在铂催化剂二氧化硅负载壳聚糖络合氯铂酸(SiO2-CS-Pt)的催化下与端羟基聚丁二烯(HTPB)硅氢加成得到双核二茂铁有机硅衍生物,并对产物的化学结构、热性能及其对高氯酸铵的催化效果进行了研究。结果表明,所得目标产物的铁含量为8.24%,初始和最终热分解温度降低,热敏感度提高,且对高氯酸铵具有良好的催化效果。In this paper,biferrocene 2,2-di(ethylferrocene)propane-organic silicon was prepared as follows:4-chlorobutyryl chloride was grafted on one end of 2,2-di(ethylferrocene)propane by Friedel-Crafts acylation,which was reduced and coupled with dimethylchlorosilane.The product was further reacted with hydroxyl-terminated polybutadiene(HTPB)in the presence of platinum catalyst(silica-supported chitosan complex of chloroplatinic acid SiO2-CS-Pt).The structure of the product was characterized by 1 H-NMR,FTIR,and TG.The grafting rate and hydroxyl value were also measured.It showed that with an iron content of 8.24 %,the initial and final thermal decomposition temperature of the product were lowered,and its thermal sensitivity and excellent catalytic performance for ammonium perchlorate were increased.
