摘要

Dagang vacuum residue (DVR) was ultrasonically extracted with fifteen organic solvents, respectively, and the soluble fractions (SFs) were analyzed with GC/MS. The results show that DVR tends to dissolve in non-polar solvent and that most of GC/MS-detectable components in the SFs are saturated hydrocarbons.
