lower the percent compositions of aspirin and the unknown because less Panacetin would be present than if all of the Panacetin was dissolved in the dichloromethane. (b) Failing to mix the aqueous and organic layers thoroughly during the NaHCO3 extraction would lead to little to no production of aspirin precipitate. The aqueous layer contains sodium hydroxide and water‚ whereas the organic layer contains the dichloromethane‚ aspirin‚ and the unknown. If the HCl has nothing to react with in the aqueous

Extraction of R’-NH2 For both of the organic acid and organic base extraction‚ the addition of the respective inorganic acid or inorganic base (HCl or NaOH) to the three-component mixture caused an immiscible appearance of the solution in the separatory funnel. By briskly shaking the separatory funnel with the mixed components created a build up of pressure which was released through the stopcock forming small disappearing bubbles within the tip of the separatory funnel. Once the funnel was placed

This experiment was designed in order to extract caffeine from coffee grounds. In order to do this‚ filtration and extraction techniques with solvents such as calcium carbonate‚ magnesium sulfate‚ and dichloromethane were used1. Decaffeination is something that’s used around the world‚ and there is much discussion on the different methods that can be used. In this case‚ using solvents and heat was the preferred method in order to extract the caffeine. Decaffeination is often used to in order to prevent
