Efficacy of Using Producer Price Indexes for Bulk Chemical Prices in Student Design Projects Engineering students are being asked to work on real-world projects and need to access accurate cost information for their design projects. In the case of chemical engineering and related disciplines, capstone courses often require designing industrial processes or a chemical plant involving bulk chemical pricing for both feedstocks and products. A lot of chemical pricing information was available in trade magazines; however, bulk chemical prices are increasingly difficult to locate as producers of that information have reduced the availability and further monetized the information over the last decade or so. The resulting information sources containing chemical pricing often cannot be acquired by academic libraries due to cost or licensing terms. In cases where current chemical prices are not available, one could use a producer price index (PPI) to adjust an older price to current levels. Using older prices and adjusting to current levels allows students access to a much larger source of chemical prices (e.g., older trade magazines). Using the PPI to adjust chemical pricing will be reviewed. In theory, adjustments using a PPI should provide accurate chemical pricing. To determine the efficacy of this approach, this study examined pricing adjustments from three information sources for 3, 5, 10, and 15 year intervals for a group of industrial chemicals to determine the efficacy of this approach. This study then discusses the relative merits and limits of using PPIs to adjust chemical prices to assist students with their design projects.
