Aldol condensation

Income Inequality, Media Fragmentation, And Increased Political Polarization by John Duca looks at the several factors that has increased polarization in the United States. First Duca examined the concept of income inequality. Income inequality is the concept that the rich get richer and the poor get poorer, and polarization is created from policies that cause that concept to only increase. Duca puts his hypothesis to test by comparing house polarization (Congress) to income inequality trends.…

producing some useful chemical products.  Reactions of aldehyde and ketones – Aldehydes and ketones response to many famous name reactions like Aldol condensation, Benzoin condensation, Cannizaro reaction, Pinacol-Pinacolone rearrangement, Beckmann rearrangement,…

there was no methanol in the pure product. A completely dried product would cause the alcohol to disappear. This is the desired spectrum. Though performing this aldol condensation reaction did not achieve acceptable yields and resulted in impurities, drying the products resulted in better data. For future experiments on aldol condensations, allowing the product is an extremely important step that should be taken to synthesize a…

TEE JIN FENG 15SPE072X 27012016 EXPERIMENT 7: Cannizzaro reaction and reaction of benzaldehyde with ethylene glycol Introduction: From the first experiment, the reaction of benzaldehyde and potassium hydroxide will produce two products which are benzyl alcohol and benzoic acid. We are going to look at how to get this two products separated by using their different chemical properties. For the second experiment, benzaldehyde ethylene acetal is formed when the reaction done under acidic…

In pursuit of our continued interest in the development of solvent-free and green synthetic procedures, we decided to explore the use of tartaric acid catalyst for synthesis of polysubstituted quinolines via Friedlander condensation in high to excellent yields at 70 °C under solvent-free conditions. Initially the reaction between 2-aminobenzophenone (1.0 mmol) and dimedone (1.0 mmol), as the model reaction was examined in the presence varying amount of tartaric acid as catalyst and the results…

1.2. Synthesis Most of the curcuminoids have been synthesized by Pabon method from most literature reports, which through the condensation of the acetyl acetone (pentone-2,4-dione)-boric oxide complex and an aromatic aldehyde in addition of tributyl borate and butylamine at 60°C with ethyl acetate as the solvent.8 This synthetic method involves aldol condensation, by forming acetylacetone-boron complex, and cleavage of the complex via hydrolysis under acidic condition. The Pabon method indeed…

self-condensation of benzaldehyde with thiamine used as the base catalyst of the reaction. The next step was the preparation of benzil from the oxidation reaction of benzoin with nitric acid. In the oxidation reaction, the alcohol functional group of benzoin was oxidized to form the carbonyl functional group of benzil, while the nitric acid was reduced into a mixture of nitrogen oxides that formed toxic brown fumes. The final step was the preparation of tetracyclone from the aldol condensation…

experiment, a series of reactions was performed in order to synthesize 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexenone, an a,b-unsaturated ketone. The two reactions performed in order to obtain this product were a Michael addition reaction and an Aldol condensation reaction. During this experiment, the reaction solution underwent several changes. Originally, the initial solution was light yellow and transparent. Once heated, the appearance of the reaction solution became bright yellow. After the…

protocols of sodium ascorbate and copper sulfate as catalyst and an equimolar ratio of water and t-butanol as solvents to yield 1,2,3-triazole linker contained intermediates (6a-b). In the final step, the intermediates (6a-b) were subjected to aldol condensation with substituted benzaldehydes in the presence of 20% aqueous NaOH solution in ethanol to get the final targeted products (7a-g and 8a-g). It may be noted that, the intermediate compound 1-(prop-2-yn-1-yl)piperidin-4-one (5) was…

Adenosine Triphosphate (ATP) is the body’s main source of chemical energy. It is produced by breaking down nutrients such as glucose, fatty acids and proteins, which are all found in food. At the start of the race, anaerobic pathways are used to provide a quick source of energy. Most of this energy is derived from the catabolism of fats. Since lipids are more reduced than carbohydrates, they are capable of storing more energy per unit weight. Triacylglycerols are the lipids used for energy…
