In this experiment, you will the oxidative cleavage of cyclohexene to produce as the only product 1,6-hexanedioic acid (adipic acid), shown in Equation 1 below. The solution was then diluted with 10 mL of cyclohexanol. Because of the narrow range, it can be determined that the product was pure. The procedure is written for a specific amount of cyclohexene. Introduction: Cyclohexanol is mainly used in the production of caprolactam and adipic acid that is a raw material of nylon 6 (Zhang, et al, 2002). We determine that the bond that is most easily oxidized is the C-H bond alpha to the carbonyl group in cyclohexanone. In order to produce the cyclohexene from cyclohexanol, an elimination reaction was performed.

During Weeks 2 and 3 of lab, you will do two experiments - Cyclohexene and … Oxidation of Cyclohexanone and Cyclohexanol to Adipic Acid. Additionally, the use of nitric acid in the preparation of adipic acid results in the emission of nitrous oxide (N Lab 7 6 O H H α Step 1 O OH H Step 2 O OH OH Step 3 [O] [O] minus H 2O O O ket one α-h ydr x k et n gem-diol diketone O O diketone [O] Step 4 O HO O OH adipic acid (1,6-hexanedioic acid) Figure 6. The first. The Format Of The Report Writing. This report describes a clean and direct catalytic method for the con- However, the standard route requires large quantities of corrosive nitric acid. The experiment yielded 0.2667 grams of adipic acid, giving a percent yield of 113.97%. Supply the usual, minus the boiling range and B.P., and determine the OH and C=O peaks by looking at the IR spectra on the following pages. Carefully add cyclohexanone, drop wise, to the small test tube until the balance shows a mass of 0.15 g. 3. One of the most important aliphatic diacids is adipic acid, which is produced industrially because of its application in the manufacture of nylon-6 and nylon-66. III. the synthesis of adipic acid from cyclohexene and H 2 O 2. On a balance, tare a small test tube that has been placed in an empty 50 to 100-mL beaker for stabilization. CPP-1.5 (1.1) Practical Organic Chemistry DOS & R in Organic Chemistry, TUT Page 2 Oxidation of Cyclohexanol or Preparation of Adipic acid from cyclohexanol AIM: To prepare Adipic acid from cyclohexanol by oxidation.
