| Abstract: | By using the method of complexation extraction and molecular distillation，the polyols in bio-based polyols distillation residues were extracted and separated. The ratio between complexing and extracting agent，and the impact of temperature and time on the outcome of extraction were investigated. The results showed that complexation extraction and molecular distillation could effectively separate polyols. |
