摘要
采用快速混合法制备了酸（盐酸、硫酸、氯乙酸等）掺杂的纳米聚苯胺纤维,扫描电子显微镜分析结果表明获得的聚苯胺纤维的直径在50～200nm之间。以松节油水合为目标反应,考察了催化剂制备条件对其催化性能的影响规律。结果表明催化剂较佳制备条件为：掺杂酸为硫酸,浓度为2.0mol/L,苯胺浓度为0.30mol/L,过硫酸铵与苯胺的浓度比为1∶1。在相同水合条件下,α-蒎烯转化率、α-松油醇的收率均达到最高值,分别为93.80%和60.60%。
Polyaniline nanofibers doped by a variety of acids（hydrochloric acid, sulfuric acid, chloroacetic acid, etc.） were prepared using rapid mixing method. Result of scanning electron microscopy showed that the diameter of the polyaniline fiber is 50-200nm. The hydration of turpentine was regarded as the goal reaction to study the effects of preparation conditions on the catalytic activity. The results showed that the optimum conditions were as follows： sulfuric acid as doping acid, molar concentration 2.0mol/L, aniline molar concentration 0.3mol/L, molar concentration ratio of ammonium persulfate and aniline 1∶1, under these conditions conversion rate of α-pinene reached 93.80%, and the max yield of α-terpineol reached 60.60%.
