Carboxylic Acids and Derivatives Conductivity of carboxylic acids, pH of acetic acid derivatives, hydrophobic effect, and soap emulsions of hydrocarbons are demonstrated.
The Preparation and Enzymatic Hydrolysis of a Library of EstersElizabeth M. Sanford and Traci L. Smith In this investigative case study, students work collaboratively to prepare and characterize a library of esters using Fischer esterification and alcoholysis of acid chlorides and their subsequent enzymatic hydrolysis by pig liver and orange peel esterases. Sanford, Elizabeth M.; Smith, Traci L. J. Chem. Educ.2008, 85, 944.

Biodiesel from Used OilRoland 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. Stout, Roland. J. Chem. Educ.2007, 84, 1765.

Biodiesel Synthesis and Evaluation: An Organic Chemistry ExperimentEhren C. Bucholtz In this two week lab sequence students synthesize fatty acid methyl esters from simulated waste vegetable oil and determine whether the glycerol concentration of the resulting product is low enough to meet the specifications for marketable biodiesel. Bucholtz, Ehren C. J. Chem. Educ.2007, 84, 296.
