摘　　要：以硬脂酸、叠氮化钠、三苯基膦及N-氯代丁二酰亚胺为原料,通过Staud inger反应及Curtius重排制备十七碳单异氰酸酯。利用十七碳单异氰酸酯的异氰酸酯基高反应活性,对氨丙基硅油进行长链烷基改性。通过控制投料比,可以调节氨丙基硅油侧链上长链脲基的引入量。以FT-IR、1H NMR对长链脲基改性氨基硅油进行结构表征,证实得到了预期的目标产物。The heptadecylisocyanate was prepared by stearic acid, sodium azide, triphenylphosphine and N- chloro succinimide as raw materials by Staudinger reaction and Curtius rearrangement. The aminopropyl silicone oil was modified by the highly reactive heptadecyl isocyanate. By controlling the feed ratio of the raw materials, the amount of long - chain uramido group on the side chains of aminopropyl silicone oil could be adjusted. The final long - chain alkyl urea - modified aminopropyl silione oil products were characterized and verified by FT- IR and ^1H NMR.
