煤焦油沥青在微型高压釜中、氮气氛下,通过改变反应温度和停留时间,制取了中间相沥青(MP).采用FTIR、偏光显微镜、XRD和SEM对MP进行了表征,表明煤焦油沥青经脱氢缩合反应转变成MP.其最佳反应条件为400℃、7h.

Mesophase pitch (MP) was produced by heating coal tar pitch in a microautoclave furnace at various temperatures and residence times under nitrogen atmosphere. FTIR, Polarized Light Microscopy, XRD and SEM were employed to characterize MP, indicating that the coal tar pitch was transformed into MP through dehydrogenative condensation reactions. The optimum yield was found at 400℃ and 7h
