Unformatted text preview: Experiment #2: Distillation Chem 2510 Purpose : The purpose of the experiment was to perform three different kinds of distillations upon three different kinds of two-solution mixtures. After distillation, the temperature and refractive index of each fraction was measured and the relative efficiencies of each method at separating compounds were evaluated. Introduction : Fifteen procedures were performed in total. Five distillation methods were employed: simple, and fractional (either using a vigreaux, scouring pads, glass beads, or carborundum chips). Three different 1:1 solution mixtures were distilled: green (methyl acetate and ethyl acetate), yellow (methyl acetate and butyl acetate) and blue (methyl acetate and n-propyl acetate). Results and Discussion: Fractional distillation with glass beads was performed on a 1:1 solution mixture of methyl acetate and ethyl acetate. The results of this trial were compared to data for six other experiments: fractional distillation using glass beads and methyl acetate:butyl acetate, fractional with glass beads using methyl acetate and n-propyl acetate, and all other distillation methods using methyl acetate and ethyl acetate (simple, vigreaux, scouring pads, carborundum). The using methyl acetate and ethyl acetate (simple, vigreaux, scouring pads, carborundum)....
