Michael Kjome Organic Chemistry Laboratory 3341 Separation and Identification of Two Unknown Compounds The separation and identification process is an important technique in organic chemistry. Depending on the substance to be separated, the techniques differ to exploit of specific characteristics of each compound. In this experiment we were asked to separate and identify two compounds. These two compounds were similar in their composition but were separated on characteristics of a ketone and an alcohol. We obtained a mixture of an unknown ketone and alcohol labeled number forty-five. Separating these two compounds out of impure mixture involved chemistry techniques such as distillation, extraction and column chromatography. We used Thin Layer Chromatography to determine the optimum solvent system to satisfy the polar solvent system. There were seven different solvent ratios tested, each having a different polarity due to the percentage of hexanes to ethyl acetate. There was a fast and a slow moving blot developed on the TLC plates. To determine which system would be best we calculated Rf values and looked for numbers that fell in the range of 0.25 to 0.35. We ended up using the solvent system number one, the most polar solvent system with Rf values of that came the closest to experimental
