摘要
通过与碳纳米纤维表面的羧基基团相互作用,乙酰丙酮氧钒和乙酰丙酮镍金属络合物嫁接到经过表面改性的碳纳米纤维上。纤维表面上的乙酰丙酮氧钒和乙酰丙酮镍对苯乙烯环氧化反应具有较高的反应活性,并且与四丁基溴化铵为混合催化剂,在CO2介质中实现了由苯乙烯"一锅"合成苯乙烯环状碳酰酯,产物产率达到51.5%。
Through interacting with carboxyl group,vanadium and nickel acetylacetonate complex are grafted on the surface-modified carbon nanofibers.According to the characterization of infrared spectroscopy,vanadium and nickel acetylacetonate complex were grafted on the surface of carbon nanofibers.The grafted vanadium and nickel acetylacetonate complex show a good reactivity to epoxidation of styrene.With tetrabutylammonium bromide as the catalyst,one-pot synthesis of styrene carbonate from styrene is realized in CO2 medium,and the yield rate is up to 51.5%.
