Biodiesel from Used Oil Roland Stout
Recently three papers have appeared in this Journal discussing the properties of biodiesel fuels and their production from biological oils, either new or used. We will frustrate students if we do not discuss why laboratory scale productions of biodiesel from used oil may produce significant amounts of emulsion.

A Greener Approach for Measuring Colligative Properties Sean M. McCarthy and Scott W. Gordon-Wylie
As a first step towards the greening of instructional laboratories, we present a new greener version of a laboratory procedure designed to measure colligative properties. The greener procedure substitutes the nontoxic, noncarcinogenic compounds stearic, myristic, lauric, and palmitic acids for the less benign aromatic compounds p-dichlorobenzene, benzil, biphenyl, naphthalene, and nitrotoluene. Achieving educational goals without the concomitant generation of chlorinated and aromatic wastes is shown here to be both possible and practical.

Soap from Nutmeg: An Integrated Introductory Organic Chemistry Laboratory Experiment Marcio C. S. de Mattos and David E. Nicodem
A sequence of experiments in which trimyristin is extracted, isolated, and purified from nutmeg, then converted to a soap (sodium myristate) and acidified to produce myristic acid.

Synthesis of Exotic Soaps in the Chemistry Laboratory Otto Phanstiel IV, Eric Dueno, and Queenie Xianghong Wang
A variety of different triglyceride sources ranging from Vietnamese garlic oil to a local restaurant's grill sludge were saponified to generate a series of exotic soaps. Students did not quantify their results, but described their products in terms of color, texture and odor.

Does Copper Metal React with Acetic Acid? Stephen DeMeo
Starting with a discrepant event and led through a series of experiments, students of an introductory chemistry course investigate if copper metal reacts with acetic acid. Finding that oxygen from the air plays an important role in the reaction of these substances, students ultimately realize that the conditions under which two reactants interact are important in determining the type of products that are made.
