摘　　要：以2-甲基-6-乙基苯胺(MEA)生产中的废弃物焦油为原料,通过化学氧化法合成了可溶性导电取代聚苯胺;利用傅立叶变换红外光谱(FTIR)、扫描电镜(SEM)等技术对样品的结构进行了表征。考察了酸浓度、氧化剂用量、聚合反应时间、聚合反应温度等合成条件对取代聚苯胺导电性能的影响,并考察了样品的溶解性能。结果表明,当盐酸浓度为1 mol/L,氧化剂/焦油物质的量比为1∶1,反应温度为10℃,反应3 h得到的取代聚苯胺样品电导率达到2.51×10^(-4)S/cm,且样品在常用有机溶剂中溶解性能良好。The soluble conductive substituted polyaniline was synthesized by chemical oxidative polymerization from 2-methyl-6-ethylaniline tar. The structure of the substituted polyaniline was characterized using Fourier transform infrared spectrometry （FTIR） and scanning electron microscopy （SEM）. The influences of the acid concentration, mole ratio of oxidants to tar, reaction time and temperature on the conduction performance of the polyaniline were investigated. The solubility of the substituted polyaniline was also studied. The results indicate that the conductivity of the substituted polyaniline could reach 2. 51 ×10-4 S/ cm under the reaction conditions as follows： 1 mol/L hydrochloric acid, mole ratio of oxidants to tar of 1, reaction temperature of 10 ℃, reaction time of 3 h. And the substituted polyaniline shows better solubility in most of organic solvents.
