Nov 15, 03 OCN 1202 Substitution Reactions with an Ambident Nucleophile (Alkylation of Soluble Saccharin) Abstract: Sodium saccharin was reacted with iodoethane in the solvent N,N-dimethylformamide and yielded a pale white crystalline product, N-ethylsaccharrin. The validity of the product was confirmed by comparing the melting point range of the product to the literature value and also by gas chromatography. Techniques Used: Thomas-Hoover Apparatus Vacuum Filtration Gas Chromatography (new) Gas Chromatography: This is a method of separating two or more different compounds/ions by their interaction to a stationary phase [carbowax] and a mobile phase [Helium]. Specifically, tubing is packed with an immobile support phase, which has a specific absorption property. This absorption property interacts with the injected gas and causes some level of immobilization (adhesion) to the polar derivative. Thus, the amount of chemical separation occurs relative to the polarity of the different compounds/ions to the immobile phase. Procedure: Approximately 75 mL of water was added to a 250-mL beaker. The...
