Organic Synthesis: Preparation & Analysis of Aspirin

In this prove we analyzed and synthesized organic compound acetylsalicylic window glass or aspirin from acetic anhydride and salicylic acid. H2SO4 was recitationd as a gun to speed up the reaction. Theory aspirin is a whizz of a least expensive and some useful drugs. From the antediluvian patriarch time people were quid salix alba to reduce fewer, in a mid nineteenth century German scientist Gerhardt cause to synthesized aspirin but his cogitation was ignored. Finally Felix Hofman (Bayer Company) manages to reduce array effects and create aspirin. aspirin is synthesized by reacting salicylic acid and acetic anhydride Acetic anhydride is a swimming 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 mark C), and taking dry and h eated cxxv ml Erlenmeyer flaskfulful .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 pelt into flask 7 drops of catalyst H2SO4, and accordingly we placed flask into water bath to heat up for 15 min.

When garland was cooled to the room temperature (around 30 degree C little sec less) we slowly added 20 ml of ice-cold water to pierce all aspirin to crystallize from solution. Crystallization slowly occurs as mixture is cooling. After full crystal we had to separate crystals from the shack of the mixture. We used vacuum filtration standard proficiency for separati! on solids from liquids synopsis of aspirin Titration and choke titration We used titration and back titration process to prefigure molecular mass. Back titration was used because aspirin is a faint-hearted acid and reaction would be truly slow if we use just titration.
