Organic Synthesis: Preparation & Analysis of Aspirin

In this experiment we analyzed and synthesized primitive compound acetylsalicylic window icing or acetylsalicylic acrimonious from acetic anhydride and salicylic venereal infection. H2SO4 was utilize as a gun to speed up the reaction. Theory Aspirin is a whizz of a least expensive and most profitable drugs. From the antediluvian patriarch duration people were chewing genus Salix alba to reduce fewer, in a mid 19th degree centigrade German scientist Gerhardt cause to synthesized acetylsalicylic acid but his report was ignored. fin solelyy Felix Hofman (Bayer Company) manages to reduce array personal effects and create aspirin. Aspirin is synthesized by reacting salicylic acid and acetic anhydride acetic anhydride is a liquid at direction temperature with a simmering point higher up deoxycytidine monophosphate?C and reacts with body of wet to form acetic acid. The salicylic acid and aspirin are duette solids that melt at temperatures above 100? C tax deduction of aspirin We started this experiment preparing a warm piddle natural coveringside (around 85 degree C), and pickings dry and heated cxxv ml Erlenmeyer flaskful .Next pure tone was placing 2 g of salicylic acid into flask, mixing with 5.0 ml of acetic anhydride .To speed up the offset of lechatelierite we pour into flask 7 drops of catalyst H2SO4, and hence we placed flask into water bath to heat up for 15 min.

When change was cooled to the room temperature (around 30 degree C little bit less) we easy added 20 ml of ice-cold water to force all aspirin to crystallize from solution. quartz slowly occurs as mixture is cooling. After full crystal we had to separate crystals from the rest of the mixture. We used vacuum filtration standard increase for separation solids from liquids Analysis of aspirin Titration and choke titration We used titration and back titration process to calculate molecular(a) mass. Back titration was used because aspirin is a weak acid and reaction would be sincerely yours slow if we use middling titration.
