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

mixed solution. 5. A mixture of ortho‚ meta‚ and para cresoles dissolved in cyclohexane may be analyzed spectrophotometrically because each exhibits an absorption in a region where absorption due to the other cresols is negligible. The absorption maxima occur at 752nm‚ 776nm‚ and 815nm for ortho‚ meta‚ and para cresols‚ respectively. To test the validity of Beer’s Law for solutions of cresols‚ each is made up in cyclohexane at a series of concentrations and the absorbances measured. Data obtained are

is to convert toluene to nitrotoluene through the process of aromatic nitration. This is done by electrophilic aromatic substitution. The aromatic organic compound‚ toluene‚ is reacted under mild conditions with an electrophile‚ the nitronium ion‚ resulting in a product of nitrotoluene. Failure to use mild conditions may result in polynitration. Different reaction conditions were studied to understand the effect of nitrating agent concentrations on the results. Initially‚ toluene is combined

more completely. The boiling point (bp) of our unknown compounds was taken from the flat regions of the fractional distillation curve. Our unknown mixture contained hexane (bp 69 ºC) and toluene (bp 110.6 ºC). Analysis via gas chromatography allowed us to determine the relative percentage of hexane and toluene at fractions near the beginning and end of our distillations. Relative percentages have been recorded in the table below‚ and our calculations are shown on page 5. Conclusion This week
