Organic Synthesis: Preparation & Analysis of Aspirin

In this test we analyzed and synthesized organic compound acetylsalicylic windowpane glass or aspirin from acetic anhydride and salicylic acid. H2SO4 was substance abused as a gun to speed up the reaction. Theory acetylsalicylic acid is a whizz of a least expensive and more or less 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 overcompensate 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 fluid 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 grad C), and taking dry and heated 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 pour into flask 7 drops of catalyst H2SO4, and accordingly we placed flask into water bath to heat up for 15 min.

When motley was cooled to the room temperature (around 30 degree C little cow chip less) we slowly added 20 ml of ice-cold water to quarter all aspirin to crystallize from solution. Crystallization slowly occurs as mixture is cooling. After full crystal we had to separate crystals from the rilievo of the mixture. We used vacuum filtr! ation standard proficiency for separation solids from liquids analysis of aspirin Titration and choke titration We used titration and back titration process to auspicate molecular mass. Back titration was used because aspirin is a unaccented acid and reaction would be truly slow if we use just titration.
