Organic Synthesis: Preparation & Analysis of Aspirin

In this examine we analyzed and synthesized organic compound acetylsalicylic windowpane glass or aspirin from acetic anhydride and salicylic acid. H2SO4 was functiond as a gun to speed up the reaction. Theory aspirin is a whizz of a least expensive and intimately useful drugs. From the antediluvian patriarch time people were wad salix alba to reduce fewer, in a mid nineteenth century German scientist Gerhardt cause to synthesized aspirin but his piece was ignored. Finally Felix Hofman (Bayer Company) manages to reduce array effects and create aspirin. acetylsalicylic acid is synthesized by reacting salicylic acid and acetic anhydride Acetic anhydride is a perspicuous at room temperature with a boiling point in a higher place 100?C and reacts with body of water to form acetic acid. The salicylic acid and aspirin are twain solids that melt at temperatures above 100? C synthesis of aspirin We started this experiment preparing a warm water lav (around 85 stage C ), and taking dry and heated cxxv ml Erlenmeyer flaskful .Next step was placing 2 g of salicylic acid into flask, mixing with 5.0 ml of acetic anhydride .To speed up the offshoot of lechatelierite we stream into flask 7 drops of catalyst H2SO4, and accordingly we placed flask into water bath to heat up for 15 min. When assortment was cooled to the room temperature (around 30 degree C little snap less) we slowly added 20 ml of ice-cold water to jam all aspirin to crystallize from solution. Crystallization slowly occurs as mixture is cooling. After full crystal we had to separate crystals from the liberalisation of the mixture. We used vacuum filtration standard proficiency for separation solids from liquids psychoanalysis of aspirin Titration and choke titration We used titration and back titration process to visualize molecular mass. Back titration was used because aspirin is a wan acid and reaction would be truly slow if we use just titration. If you want to get a full! essay, secern it on our website: OrderCustomPaper.com
