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

The synthesis of meso-1‚2-dibromo-1‚2-diphenylethane was successful as the final product of the experiment had the same physical properties of the theoretical properties‚ which were determined by TLC and melting point. The synthesis of diphenylacetylene was also successful‚ as TLC and the melting point both proved its identity‚ however the UV-vis analysis went awry due

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

While in 1894 he began working for the Bayer pharmaceutical research facility in Elberfeld‚ Germany as a chemist. On August 10‚ 1897 Felix Hoffmann invented a medicine called Aspirin. It
Premium Aspirin Salicylic acid Acetic anhydride
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

Preparation of an Ester Acetylsalicylic Acid (Aspirin) OBJECTIVE: To become familiar with the techniques and principle of esterification. DISCUSSION: Aspirin is a drug widely used as an antipyretic agent (to reduce fever)‚ as an analgesic agent (to reduce pain)‚ and/or as an anti-inflammatory agent (to reduce redness‚ heat or swelling in tissues). Chemically‚ aspirin is an ester. Esters are the products of reaction of acids with alcohols‚ as shown in the following equation using

Response for Case Datril 1) What course of action should Datril take? It should solidify its position in the analgesic market and gain share in the rapidly growing acetaminophen market. It should target both Tylenol Users and Aspirin Users. On one hand‚ it should explain to customers that Datril’s effect is identical to Tylenol and use low-price promotion. On the other hand‚ it should leverage Bristal-Myers’s name to facilitate its market penetration. Generally‚ it should focus on advertisement
