摘要：首先制备了水溶性羟基化多壁碳纳米管,然后用聚乙烯吡咯烷酮(PVP)进行处理,得到了聚乙烯吡咯烷酮包裹的羟基化多壁碳纳米管。采用扫描电子显微镜、激光粒度分布仪和红外光谱仪等手段对样品进行表征和分析。结果表明:聚乙烯吡咯烷酮包裹的羟基化多壁碳纳米管在水溶液中的溶解度明显增加,水溶液分散均匀、稳定性好,长期在室温下保存无聚集和沉淀。
Ani l ine and acetic einhydride was used as raw materials, with ultrasonic technology for preparation of acetanilide. The effect of the amount of acetic anhydride, the reaction time and the volume of ether on the synthesis of acetyl aniline was studied. The results showed that the yield of acetanilide could be as high as 89.31% , with the molar ratio of einiline and acetic anhydride being 1 ： 1.2, ultrasonic radiation being 30 min,the dosage of extracted acetyl aniline being 20 mL. Compared with the conventional method,the ultrasonic one not only saved the tedious process of heating, but shortened the reaction time, improved the reaction rate, and the yield was higher with more environmental protection.
