引言各种沥青热转化为中间相和焦碳包含着聚合反应。中间相在碳化过程中的重要性已引起极大的重视,然而,沥青聚合作用的动力学研究却十分有限,已完成的少量动力学研究,均以测定沥青的溶介度、碳氢比和游离基含量等的变化为依据。此外,沥青含有大 INTRODUCTION The thermal conversion of various bitumen to mesophase and coke involves polymerization. The importance of the mesophase in the carbonization process has drawn great attention. However, the kinetics of the polymerization of asphalt has been very limited. A small amount of kinetic studies have been done to determine the solubility of asphalt, the hydrocarbon ratio and Free radical content and other changes as the basis. In addition, asphalt contains large
