Identifying a Constituent of “Panacetin” Essay

The Consulting Chemists Institute has been asked to analyze the medicate planning of acetylsalicylic acid to find out what percentages of acetylsalicylic acid, saccharose, and drug preparation. The purpose of this experiment was to determine the chartless component of panacetin. Panacetin contains aspirin, sucrose, and an unknown component. Dichloromate reacts with Panacetin to produce the sucrose as an insoluble solid. Aspirin is take away from the solution by reacting with atomic number 11 bicarbonate. The sedimentary layer reacts with hydrochloric acid, the unknown component roll in the hay then be isolated by evaporating the solvent from the methylene chloride solution.Observations and DataAspirin reacted with Sodium Bicarbonate to form salt, atomic number 11 acetylsalicylate. The reaction caused fizzing and gas. When hydrochloric acid was added to sodium acetylsalicylate the solution bubbled, sizzled, and gave off heat. All precipitates were white. trade unionMassPana cetin3.00gAspirin0.849gsaccharose0.212g (weighed wet) isolated1.995 (burned)Results and DiscussionThe results I got were close to the expect results. During the Isolation of the Unknown component, water splosh on our sucrose sample in the lead we could weigh it and we burned the unknown, skewing the tidy sum. However, there could give up been incomplete mixing with dichloromethane, incomplete inception of precipitation of aspirin, incomplete drying of the recovered components, orlosses from transferring substances from one container to another.Calculations% Recovery = sum of the masses of all components/mass of panacetin started with0.212g+0.849g+1.995g/3.01g = one hundred one%%Composition = (Amount of Component/Sum of the masses of all components)* speed of light%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% observational3.01g of Panacetin was dissolved in 50mL of dichl oromethane. The mixture was regularize with gravity filtration. Sucrose was garb aside. The filtrate was then put through a separatory funnel and put into twain 30mL portions of 5% sodium bicarbonate. 11mL of 6M hydrochloric acid was tardily added to the mixture. The mixture was cooled for ten minutes and aspirin was collected via vacuum filtration. A pick up flask attached to a seaman and aspirator was used to evaporate the solvent from the dichloromethane solution. All precipitates were white and crystalized.
