Chem 2203 Sec 026 27/September/2013 Experiment 3B: Fractional Semi-microscale Distillation Separation of Hexane and Toluene. Objective: The main goal of this lab is to learn how separation of binary liquid mixtures is performed. Especially when the two liquids have boiling points varying by about 30° C. Hexane can be separated from toluene in this experiment because of the difference in their boiling points. Since toluene has a higher boiling point‚ it will left at the bottom while the hexane

2014 Experiment 4: Extraction and Chromatic Separation of Plant Pigments from Tomato Paste ABSTRACT In column chromatography a mixture is dissolved in a solvent and poured over a column of solid adsorbent then eluted with the same or a different solvent. This method is often used for preparative purposes; when a relatively large amount of the mixture and the components need to be isolated. The two main pigments in tomato paste mixture are the yellow-orange β-carotene and the red lycopene
