Abstract

From near-infrared spectrophotometry measurements, flocculation onset for an Algerian asphaltene in different toluene/non-solvent solutions were detected. The Hansen solubility parameters of the extracted asphaltene and sub-fractions were calculated and compared to ones of a set of good and bad solvents. The ranking of the different solvents according to Hansen solubility sphere method shows that chloroform and quinoline may be the best solvents for dispersing polar asphaltene fractions.

阿尔及利亚沥青及其亚分形的Hansen溶解度参数的确定

摘要

通过近红外分光光度法测量，可以检测到阿尔及利亚沥青质在不同甲苯/非溶剂溶液中的絮凝开始。计算了提取的沥青质和子级分的汉森溶解度参数，并将其与一组好的和坏的溶剂中的一个进行比较。根据汉森溶解度球法对不同溶剂的排名表明，氯仿和喹啉可能是分散极性沥青质馏分的最佳溶剂。
