After steam distillation, eugenol was extracted via centrifuge extraction and the percent yield and IR analysis was completed. endobj What parameters affected the efficiency of your distillation? The error might happened due to the apparatus lid was not completed sealed, and some gas escaped. When two liquids are mutually soluble their molecules interact with one another by van Then, the pure 2-methylpentane was collected in the receiving flask. cyclohexane. The purpose of this experiment was to introduce the technique of simple distillation for the separation. soluble in 2.2: Distillation - Chemistry LibreTexts Theresultant In this specific experiment, fractional distillation works better due to the small different boiling points between 2-methylpentane (60) and cyclohexane (81). 5. openings.
