Recrystallization and Identification of Unknown

Abstract: In this lab an unknown, contaminated organic compound, ā€œEā€, was given to be purified and identified. The compound was identified to be N-Phenysuccinimide, because it had a melting range of 154.3-155.5 degrees Celsius. When the purified compound was mixed with known N-Phenylsuccinimide, the melting range was not depressed at all confirming the results. An appropriate solvent was found among water, acetone, ethanol and toluene by doing small-scale solubility tests. To purify the N-Phenylsuccinimide, it was dissolved in hot ethanol, […]
