scale experiments.1 Chromium (III) benzoquinone complexes can oxidize alcohols to aldehydes or ketones, and these complexes may be able to catalytically carry out the oxidation.2 The complexes may be made by preparing Cr(ClO4)2 and reacting it with a substituted benzoquinone and nitrogen donor ligands. Those ligands could be in this specific case, tetradentate ligands, meaning they will bind four donor atoms to a central atom in order to form a reduced coordination complex. Once the reduced form is produced, a reduction-oxidation reaction can be used to form the oxidized form. Many different methods were attempted to accomplish this, and the results will be reported.

Chromatographic Analysis of Common Analgesic Compounds Using TLC, LC, and HPLC (P)

Faculty Project Advisor: Jimmy Davis

The purpose of this research project was to analyze commonly used over-the-counter analgesic drugs using thin layer chromatography, column chromatography, and high-pressure liquid chromatography. The goal was to create a useful Organic Chemistry lab for students to perform in an effort to learn how to use these techniques. In addition to learning how to use these chromatography techniques, students will be able to identify similarities and differences between the techniques, as well as the molecular reasoning that explains the results of each run. n
