Chem 262L Francisco Andrade The Oxidation of Isoborneol Purpose: The purpose of this experiment is to use chromic acid to oxidize isoborneol to camphor, which is subsequently recovered by purification via sublimation. Balanced Chemical Equation: Procedure: To a 10 mL Erlenmeyer flask, 2.3 mmol of isoborneol was added. A stirring bar and 1 mL of glacial acetic acid were added, and the solution was gently heated on a hotplate until the temperature reached 50 o C. To the solution, 2 mL of the chromic acid solution was added dropwise. The temperature was always kept below 60 o C, and cooling in an ice water bath served to lower the temperature. After 15 minutes, the mixture was poured into 25 mL of ice water and suction filtered. Once the product was completely dry, a sublimation apparatus was set up, and some of the product was sublimed using the aspirator vacuum. The melting points of the crude and pure products were measured. Discussion and Data Analysis:
