Oxidation Of Cyclododecanone Lab Report
Oxidation of Cyclododecanol Bo Schuetz Chem 34l Section 004 10/29/2024.
Introduction Goal: The objective of this experiment was to convert cyclododecanol, a secondary alcohol, into cyclododecanone, a ketone, through an oxidation reaction using sodium hypochlorite (NaClO) as the oxidizing agent. Oxidation reactions of alcohols are fundamental in organic synthesis, as they enable chemists to selectively introduce new functional groups, which can subsequently be used to build more complex molecules. The goal of this reaction was not only to achieve the transformation of cyclododecanol to cyclododecanone but also to examine the practical applications of using a mild and accessible oxidizing agent like NaClO, which is commonly found in household bleach.

Characterization Methods: The final product, cyclododecanone, was analyzed by infrared (IR) spectroscopy to confirm the oxidation of the hydroxyl group to a carbonyl group. In IR spectroscopy, the presence of functional groups can be identified by their unique vibrational frequencies. There also were some other characterization tests such as the yield and the melting point. Procedure: The experimental procedure was designed to ensure accurate and reproducible results while prioritizing safety. The setup involved combining 0.5 g of cyclododecanol, 1.2 mL of acetone, and 0.4 mL of glacial acetic acid in a 25 mL round-bottom flask. To facilitate even mixing, a stir bar was placed inside the flask. The flask was then securely positioned in a cloth heating mantle on a stir plate, with a condenser attached to allow reflux without the loss of volatile components. The glass joints were sealed with a thin layer of grease to prevent vapor leakage. The mixture was gradually brought to a gentle reflux by adjusting the variac. Once at reflux, 8 mL of NaClO (bleach) was added dropwise over a period of 15 minutes. This controlled addition rate was
