242L-002 February 20‚ 2013 Oxidation of Cyclohexanone to Adipic Acid Abstract The cyclic ketone cyclohexanone was oxidized to adipic acid using the oxidizing agent nitric acid. The experiment yielded 0.2667 grams of adipic acid‚ giving a percent yield of 113.97%. Although the product was allowed to dry for one week‚ residual moisture was still present in the sample and a melting point could not be obtained. This error in the experiment either resulted from adding too much water or not allowing

A physical change is one that affects only the physical properties of a substance‚ while a chemical change alters a substance at the molecular level. Physical Properties: A property that can be observed or measured without changing the chemical identity of the substance. Physical properties can be categorized as either intensive or extensive. Reactivity: An element or compound’s reactivity is its ability or capacity to react‚ or bond‚ with another substance. As you continue through this course

Monica Perez Experiment 8: Acetylsalicylic Acid Experiment 01/25/2013 CHM Lab- 2211 Sec 0016 Instructor: Jennifer Reed Introduction: Commonly used as Aspirin‚ acetylsalicylic acid is an analgesic (pain reliever)‚ which is one of the products of the esterification reaction between salicylic acid and acetic anhydride. This esterification occurs since the hydroxyl group from the salicylic acid reacts with acetic anhydride to form an ester. In this experiment‚ we will be able to recreate

We were able to collect a total of 75.50% percent yield. Some of the loss of product could be due to the constant transfer of the solution. Throughout the experiment the solution was moved from the flask to the vacuum filter‚ and then to another flask some of the loss could have happen there. The infrared
