对煤沥青中喹啉不溶物分析方法的改进

Improvement of the Determination Method for Quinoline Insoluble Materials in Coal Pitch

针对在试验过程中发现煤沥青中喹啉不溶物分析结果偏高的现象,根据煤沥青中甲苯不溶物的测定原理,找到造成这种现象的原因,然后从不同的角度进行试验,最终摸索出一套分析煤沥青中喹啉不溶物含量的简单、经济、可行的方法。

The reason of the higher value of quinoline insoluble material in coal pitch is analyzed through the determination theory of methyl benzene insoluble material. A simple, economical and feasible method is suggested to analyze the quinoline insoluble material based on several trial tests.
