Name Period Date The Synthesis of Aspirin Background Pharmaceutical research labs perform chemical reactions between organic molecules that contain mostly carbon. Since the atoms in organic molecules tend to be nonmetals‚ then the bonds that hold them together are covalent bonds. Only a few elements on the periodic table are nonmetals: C‚ N‚ O‚ S‚ Cl‚ and F. This small number of elements can be bonded together in different quantities‚ bonding types (single‚ double‚ triple bonds)‚ and structural

The purpose of our experiment was to synthesize aspirin from acetyl anhydride‚ salicylic acid‚ and sulfuric acid. And then determine the relative purity of the synthesized sample. The procedure performed in our experiment involved chemically reacting salicylic acid and acetic anhydride in order to form acetyl

Preparation and purification of acetylsalicylic acid Results and Data treatment (A) Preparation of aspirin i) Details about the reactants Reaction of the acetylation of salicylic acid is following From the balanced reaction above‚ it can be seen that the stoichiometry between salicylic acid and acetic anhydride is 1: 1. In this experiment‚ 21.7mmol of salicylic acid was used to react 6.0mL of acetic anhydride and salicylic acid was limiting reagent. The expected amount of salicylic

Analgesics Analgesics‚ or painkillers‚ come in many varieties. Most consumers know the various brand names‚ but may not know that they are in different pharmacological classifications. For instance‚ Tylenol and Motrin are two drugs that behave differently on the human body to achieve similar results. While most consumers do not think about what they put into their bodies‚ maybe they should. They would find that the various painkillers could markedly affect the body differently. The most popular

used for a long time by loyal customers who get recommendations from medical professions. It means the existing customers were likely not price-sensitive compared to aspirin customers. Datril is not able to offer an effective differentiated value to these customers compared to Tylenol. Therefore Marvin Koslow should target at aspirin users who were lightly suffering from irritation of stomach lining and who didn’t visit doctors. ‘No side effect’ is more valuable to these customers. As we target these

Experiment: The OH group on the benzene ring in salicyclic acid reacts with acetic anhydride to form an ester functional group. Thus the formation of acetylsalicyclic acid (aspirin) is referred to as an esterification reaction‚ which requires the presence of H+ (H2SO4 in our case). The technique used to purify the aspirin content is called crystallization‚ which consists in allowing the reaction to cool‚ decreasing the solubility of acetylsalicyclic acid and allowing it to crystalize. To purify
