Abstract: A method of solvent extraction to separate heavy aromatics was adopted from furfural extraction oil, which is used to produce rubber softener. This provides a good technique for taking good advantage of the extraction oil. The results show that with the furfural as the extract reagent, under the condition of the extract temperature is 60 ℃， the mass ratio of solvent to oil is 2.0， extract time 3 min，the sedimentation time is 30 min. After furfural extraction, the rubber softener satisfies the standard of rubber softener. A good macromolecule aromatics rubber softener would be obtained, and the remained oil can be used as the raw material of FCC. So this technology has good application potentials.
