Title: Separation and Identification of Organic Unknowns Aim: The purpose of this laboratory experiment was two-fold, first, to demonstrate the extraction of acidic, basic and neutral components from a crude product, finally determining what unknowns were present using some common analytical procedures and techniques. Introduction: An organic crude product obtained from a 'worked up' reaction mixture will in almost all cases need to be purified further. The work-up, by which this procedure is usually known, simply refers to the isolation of the product from the reaction mixture, free from solvent and spent reagents, and does not imply any purification. In order to purify an organic compound by separating the impurities, one has to rely on the desired compound having different properties to the impurities. Differences that may be taken advantage of are: differences in solubility, volatility, polarity, shape and functional groups present. For example, crystallisation relies on the differences in solubility between the desired compound...
