much pure aspirin as possible. The reactants‚ acetyl anhydride and salicylic acid‚ must react in phosphoric acid. With phosphoric acid as a catalyst‚ the reaction yields aspirin and acetic acid. The equation for the reaction is as follows: “(CH3CO)2O + HOC6H4COOH □(→┴yields ) CH3CO2C6H4CO2H + CH3COOH” (French et al‚ 82). Aspirin and salicylic acid have similar properties‚ but many choose aspirin for medicine because it is not as acidic as salicylic acid. The limiting reagent limits how much product

addition of a few drops of concentrated sulfuric acid‚ which catalyzed the reaction. The percent yield is calculated to determine the effectiveness of the reaction in preparing the desired product (aspirin). The limiting reactant of the equation was salicylic acid. After the limiting reactant was determined‚ the theoretical yield of aspirin was calculated at approximately 1.97g. The actual yield was only around 0.67g‚ producing a percent yield of 34.3%. These results show that the methods used were

Strategic Competitive Outcomes After its international strategy and mode of entry have been selected‚ the firm turns its attention to implementation issues (see Chapter 11). Implementation is highly important‚ because international expansion is risky‚ making it difficult to achieve a competitive advantage (see Figure 8.1). The probability the firm will be successful with an international strategy increases when it is effectively implemented. International Diversification and Returns Firms

Report One I have been a long time sufferer of migraines and I never knew what the cause of my migraines was. I was on a prescription for a while for my migraines but having to take a pill every single day is a real hassle. People who are migraine sufferer’s can relate to the fact that they are not pleasant and tend to ruin your whole day. If one were able to know what the cause of their migraines was‚ no one would have to worry about being in the middle of an important task and not be able

Synthesis of Tetraphenylcylopentadienone Post-Lab Report Purpose- This experiment illustrates the use of adol condensation for the synthesis of a five-membered carbocylic ring. It is also a good demonstration of the impact extended conjugation has on the absorption of visible light. The reactants are bright yellow in color while the products are a very deep purple color appearing almost black. Introduction- The synthesis of Tetraphanylcyclopentadienone was a further example of the adol
