Study on the synthesis of n-butyl acetate catalyzed by ammonium peroxydisulfate 过硫酸铵催化合成乙酸正丁酯的研究
Study on Determination of Reaction Rate Proceeding with Part Invalid Ammonium Peroxydisulfate 部分失效过二硫酸铵测定反应速率的实验研究
Polyaniline nanofibers and nanotubes have been prepared by direct mixed reaction with aniline and ammonium peroxydisulfate in acetic acid system. The main influence factor of polyaniline morphology and yield is the ratio of aniline to ammonium peroxydisulfate. 在醋酸体系中,采用直接混合反应法可合成出纳米纤维和纳米管,反应物配比是产物形貌和产率的主要影响因素。
The results demonstrate that the concentration of aniline, mole ratio of aniline to ammonium peroxydisulfate ( APS), polymerization temperature, polymerization time, types of acid and the acidity have significant effect on the morphology of PANI product. 苯胺浓度、苯胺与过硫酸铵的摩尔浓度比、聚合温度、酸度和聚合时间对聚苯胺微球的形成有重要影响。
