TECH 704 Separating Cyclohexane and Toluene by Distillation INTRODUCTION Distillation is a process which separates compounds based on distinct boiling points. Organic compounds that have fairly high vapor pressures and low boiling points can be deemed volatile. In this lab, a mixture of cyclohexane and toluene will be put through two separate distillation processes, a simple distillation and a fractional distillation. Simple distillation only boils the liquid, collecting the vapors with a cool pipet, causing the vapors to condense. Fractional distillation includes many more materials. EXPERIMENTAL PROCEDURE For the simple distillation, the pre-mixed solution was poured into a test tube. A boiling chip was added and the solution was brought to a boil using a sand bath. When solution began to boil, its vapors were slowly collected using a cool Pasture pipet, where the vapors condensed, and transferred into a separate vial. This process was repeated until about half of the mixture was remaining. The vial was covered to prevent evaporation and the remaining mixture was
