Synthesis of Albendazole Metabolite: Characterization and HPLC Determination Graciela Mahler, Danilo Davyt, Sandra Gordon, Marcelo Incerti, Ivana Núñez, Horacio Pezaroglo, Laura Scarone, Gloria Serra, Mauricio Silvera, and Eduardo Manta In this laboratory activity, students are introduced to the synthesis of an albendazole metabolite obtained by a sulfide oxidation reaction. Albendazole as well as its metabolite, albendazole sulfoxide, are used as anthelmintic drugs. The oxidation reagent is H2O2 in acetic acid. The reaction is environmental friendly, fast, and proceeds with high yield. The crude reaction is analyzed by HPLC chromatography to determine purity. The simplicity of the experiment allows students to study chiral concepts, physicochemical and spectroscopic properties of the compounds, and HPLC determinations.

Laboratory Experiments on the Electrochemical Remediation of the Environment. Part 8. Microscale Simultaneous Photocatalysis Jorge G. Ibanez, Rodrigo Mena-Brito, and Arturo Fregoso-Infante In this article we describe a microscale experiment in which the simultaneous oxidation of an organic compound (citric acid) and the reduction of a metal ion (Cu2+) are photocatalytically performed in an aqueous slurry containing TiO2 irradiated with UV light. This produces electrons (capable of reducing the metal ions) and holes (capable of oxidizing the organic molecule) that can be used for environmental clean up. The experiment allows students to have a better comprehension of the different phenomena involved in a typical photocatalytic process. Ibanez, Jorge G.; Mena-Brito, Rodrigo; Fregoso-Infante, Arturo.

Making Usable, Quality Opaque or Transparent Soap Suzanne T. Mabrouk First-year and organic chemistry students will learn the chemistry of soap by making some of the eleven described formulations, which produce usable, quality bars of soap. Opaque and transparent soaps are made in two and three hours, respectively. With an introduction to formulation chemistry, organic chemistry students can devise a formulation to synthesize their own opaque soap. Many of the formulations use commonly-available fats and oils, while some formulations incorporate specialty fats and oils for therapeutic purposes, for example, to relieve dry skin or itching.

Circular Dichroism Investigation of Dess–Martin Periodinane Oxidation in the Organic Chemistry Laboratory Nicole A. Reed, Robert D. Rapp, Christian S. Hamann, and Pamela G. Artz Using circular dichroism, organic laboratory students investigated the change in absolute stereochemistry upon oxidation of menthol to menthone. In the first laboratory period, the oxidation was performed with DessMartin periodinane, which is a facile and less toxic oxidizing agent. Half the laboratory group performed the oxidation with ()-menthol and the other half used (+)-menthol to produce ()-menthone and (+)-menthone, respectively. The products were analyzed in the second laboratory period using infrared spectroscopy and gas chromatography/mass spectrometry to determine the fraction of starting alcohol converted to ketone. Comparison was made between CD spectra both for the menthol reactant and menthone product and for the (+)- and ()-menthone enantiomers.

Single-Molecule Electronic Measurements with Metal Electrodes Stuart Lindsay The process of transferring electrons from one metal electrode to another via an intervening molecule differs from electrochemically or optically-induced electron transfer in important ways. The simplest process of ballistic electron transport with no charge localization on the molecule (tunneling) should be easy to understand quantitatively, yet experimental reports and theoretical calculations can differ by orders of magnitude. Here, we show how many of the discrepancies are resolved with measurements carefully constructed to provide data on single molecules connected to electrodes in well-defined ways. Lindsay, Stuart. J.

Volatile Organic Sulfur Compounds of Environmental Interest: Dimethyl Sulfide and Methanethiol. An Introductory Overview Thomas G. Chasteen and Ronald Bentley Volatile organic sulfur compounds and their degradation products play important environmental roles in global warming, acid precipitation, and cloud formation. Two important members of this group, dimethyl sulfide, DMS, and methanethiol, MT, are formed by living organisms as well as by abiotic processes. The chemical reactions responsible for the biosynthesis of DMS and MT are emphasized here, as well as means for their degradation. Since sulfur compounds are often ignored in normal course work, this article provides a basic foundation for an understanding of these interesting and environmentally significant compounds.

Studying Current–Potential Curves Using Bipotentiometric Iodometric Back-Titration for the Determination of Ascorbic Acid in Fruits and Vegetables Roxana A. Verdini and Claudia M. Lagier A method for the determination of the ascorbic acid content in fruits and vegetables was used to introduce the principles of voltammetry. The procedure combines an iodometric back-titration with voltammetric (bipotentiometric) end point detection, which minimizes the risk of ascorbic acid oxidation, allowing for a rapid and efficient quantification of vitamin C in fruits and vegetables. A better understanding of the titration curve is achieved by analyzing the schematic currentpotential curves of the anodic and cathodic half-cell reactions during the titration.

The Relative Explosive Power of Some Explosives Marten J. ten Hoor The efficiency of an explosive is measured by its relative explosive power, REP. This quantity is defined as REP = QVg/m2, where Q is the energy released in the explosion, Vg is the total volume (at STP) of gas produced, and m is the mass of the explosive that has reacted. These three quantities can be determined from the explosion equation of the explosive. ten Hoor, Marten J. J. Chem. Educ. 2003, 80, 1397.

Redox Buffer Strength Robert de Levie The proper functioning of enzymes in bodily fluids requires that the pH be maintained within rather narrow limits. The first line of defense against large pH fluctuations in such fluids is the passive control provided by the presence of pH buffers. It is equally important for many enzymes that the redox potential is kept within a narrow range. In that case, stability of the potential is most readily achieved with a redox buffer. In this communication the redox buffer strength is defined by analogy with acid-base buffer strength. de Levie, Robert. J. Chem. Educ. 1999, 76, 574.

Slide Projector Corrosion Cell Silvia Tejada, Estela Guevara, and Esperanza Olivares The process of corrosion can be demonstrated in a slide projector, since the cell is in the shape of a slide, or on the stage of an overhead projector by setting up a simple galvanic cell. Corrosion occurs as the result of a galvanic cell reaction, in which the corroding metal acts as the anode. Several simple demonstrations relating to corrosion are described here.

Free Radical Reactions in Aqueous Solutions: Examples from Advanced Oxidation Processes for Wastewater from the Chemistry in Airborne Water Droplets N. Colin Baird A common free radical reaction in aqueous solution is electron transfer, especially to the hydroxyl radical and to ozone. Hydrogen peroxide and free radicals related to it act as weak acids, so both their neutral and deprotonated forms must be considered in reactions. Free radical reactions also play an important role in the chemistry of water droplets suspended in air in clouds and fogs. Baird, N. Colin. J. Chem. Educ. 1997, 74, 817.

Valency Peter G. Nelson The concept of valency is refined and developed. Three types of valency are distinguished : primary or classical, coordinate, and nonclassical. The first relates to simple compounds and to the components of multiple ones, the second to coordination compounds, and the third to transition-metal carbonyls and similar species. Each type is defined, evaluated, and applied to the prediction of the atomic composition of compounds. Nelson, Peter G. J. Chem. Educ. 1997, 74, 465.
