Steam Distillation of Lemongrass Oil I. Introduction When a mixture of cyclohexane and toluene is distilled‚ the boiling point of these two miscible liquids is between the boiling points of each of the pure components. By contrast‚ if a mixture of benzene and water (Immiscible liquids) is distilled‚ the boiling point of the mixture will be found below the boiling point of each pure component. Since the two liquids are essentially insoluble in each other‚ the benzene molecules in a droplet of

Procedure Three test tubes were placed in a test-tube rack. A clean eye dropper was used for each alcohol and 4 drops of 1-butanol were placed in the first tube; 4 drops of 2-butanol were placed in the second tube; and in the third tube‚ 4 drops of 2-methyl-2-propanol were placed. After the 4 drops of each alcohol were placed in the test tubes‚ the next step was to add 10 drops of concentrated hydrochloric acid (HCl) to each of the three test tubes. The mixtures were shaken very gently and the tubes
