Identifying a Constituent of “Panacetin” Essay

The Consulting Chemists Institute has been asked to analyze the drug preparation of acetylsalicylic acid to find out what percentages of aspirin, sucrose, and drug preparation. The purpose of this experiment was to determine the inexplicable component of panacetin. Panacetin contains aspirin, sucrose, and an hidden component. Dichloromate reacts with Panacetin to produce the sucrose as an insoluble solid. aspirin is removed from the solution by reacting with sodium bicarbonate. The aqueous layer reacts with hydrochloric acid, the unknown component can indeed be isolated by evaporating the answer from the dichloromethane solution.Observations and DataAspirin reacted with Sodium Bicarbonate to form salt, sodium acetylsalicylate. The reaction caused fizzing and gas. When hydrochloric acid was added to sodium acetylsalicylate the solution bubbled, sizzled, and gave off heat. each(prenominal) precipitates were discolor.SubstanceMassPanacetin3.00gAspirin0.849gSucrose0.212g (weighed wet)Unknown1.995 (burned)Results and DiscussionThe results I got were close to the expected results. During the Isolation of the Unknown component, water splashed on our sucrose sample before we could weigh it and we burned the unknown, skewing the masses. However, there could take up been incomplete mixing with dichloromethane, incomplete extraction of precipitation of aspirin, incomplete drying of the corned components, orlosses from transferring substances from one container to another.Calculations% Recovery = sum of the masses of both components/mass of panacetin started with0.212g+0.849g+1.995g/3.01g = 101%%Composition = (Amount of Component/Sum of the masses of either components)* nose candy%Composition of Sucrose = (0.212g/3.056g)*100=6.9%%Composition of Aspirin = (0.849g/3.056g)*100= 27.8%% Composition of Unknown = (1.995g/3.056g)*100= 65.3%Experimental3.01g of Panacetin was dissolved in 50mL of dichloromethane. The smorgasbord was put through gravity filtration. Sucrose was set aside. The filtrate was then put through a separatory funnel and put into two 30mL portions of 5% sodium bicarbonate. 11mL of 6M hydrochloric acid was slowly added to the mixture. The mixture was cooled for ten minutes and aspirin was collected via vacuum filtration. A filter flask attached to a trap and aspirator was used to evaporate the solvent from the dichloromethane solution. All precipitates were white and crystalized.
