摘　　要：讨论了神府煤制备磺化煤的反应中,磺化温度、时间对煤磺化度和酸性基的影响,用FTIR对磺化煤进行结构表征,用体积溶胀法研究了磺化煤在苯胺中的溶胀特性.结果表明,煤的磺化度随着磺化温度的升高、磺化时间的延长而增大,煤经过磺化反应后其在苯胺中的溶胀性能也得到了改善.In the sulfonation reaction of coal, the effect of sulfonation temperature and time on the sulfonation value and acid groups of coal were researched, the structure of the sulfonated coal were identified by FTIR, the swelling property of sulfonated coal in aniline were studied by swelling. The result showed that the acidity of coal increased with the increase of temperature and time, the swelling property of coal in aniline were improved by the sulfonation reaction.
