Purpose Acetophenetidin can be formed through two methods‚ Williamson ether synthesis and amide synthesis. By working in groups of two we were able to complete both methods of synthesis routes. The end result should be the synthesis of a similar product‚ by verification between the two individuals. Reaction Experiment and Observations Amide Synthesis of Acetophenetidin The Synthesis reaction began by removing the colored impurities from the p-phenetidine‚ accomplished by mixing

In our ecocolumn many changes occurred over the several week course we were observing and collecting data on the three chambers. Aquatic and Decomposition quickly turned septic while terrestrial experienced plant growth. Overall the health of the ecosystem was very poor due to the severe changes in the aquatic chamber. Terrestrial In the Terrestrial camber of our ecocolumn‚ several changes happened over time. The clover seeds planted at the beginning had a rapid growth rate. At one point our chamber

It is so crucial because it allows for the understanding of how molecules interact in order to create new products. Generally speaking‚ multistep synthesis could be useful in a practical application such as pharmaceutical chemistry. Synthesizing aspirin is a common example of a multistep synthesis reaction. Aspirin is typically taken as a painkiller or as a reducing-agent for fevers. In order to synthesize this product‚ the reactants salicylic acid and acetic anhydride

Synthesis of Aspirin (Acetylsalicylic Acid) Abstract: This experiment is about the synthesis of aspirin under laboratory conditions. Aspirin is prepared by reacting salicylic acid and acetic anhydride; in the presence of sulfuric acid. After fully dissolving the salicylic acid with acetic anhydride‚ the solution is cooled and cold water is then added. Once the crystals form they are then filtered and left to dry out. There mass is measured and recorded then the yield is calculated. Introduction:
