    mixture is dissolved in diethyl ether (common name is ether). Both components are soluble in this solvent. Then a 1 M NaOH solution is used to extract the benzoic acid in the form of its water-soluble salt‚ sodium benzoate (three extractions to ensure complete removal)‚ leaving the neutral compound in the ether layer. The three aqueous extracts are combined and the two components are recovered as follow: 1. The neutral compound by washing‚ drying and evaporating the ether layer. 2. Benzoic acid by

    Introduction The purpose of this lab is to synthesize Lidocaine from 2‚6-dimethylaniline‚ using diethyl amine‚ 2-chloroacetyl chloride‚ acetic acid‚ and toluene. The Lidocaine was made by adding 2‚6-dimethylaniline to 2-chloroacetyl chloride in acetic acid. Sodium acetate is added in order to make the compound soluble. The product is dried‚ then treated with diethyl amine and toluene. This is refluxed using a water-cooled reflux condenser. The vapor is condensed by the cold water as the compound

    122°C. Therefore‚ there were errors that occurred within the experiment. One source of error was from the separation process. Some of the aqueous solution in the separatory funnel containing the ether could have potentially been drained off with the product and the NaOH. This would have caused some ether to remain in the final product which would cause a larger molecular weight to occur and the product would have a lower melting point. Another source of error could have been having leftover impurities
