The Properties, Reactions, and Separations Facility provides outstanding access to expertise in thermodynamics and phase equilibria, catalysis, kinetics, distillation, and reactive distillation.

The facility capabilities include catalyst characterization, kinetics and phase equilibra. The facility features two distillation columns that can be configured in a 10-m bay, a 70L glass reactor for prep of pilot scale reactions, and a 4" wiped film still. The facility has excellent in-house analytical facilities and access to centralized equipment including NMR, IR, and GC-MS.

The facility staff has extensive experience with reactive distillation. Reactive distillation is ideal for reactions that are difficult to drive to completion without separation of one of the products. Such reactions are called 'equilibrium limited'.

The NRTL-PA Aspen user model is now available for download. This model enhances the capabilities of Aspen to blend the capabilities of NRTL with that of the Wertheim association approach.
Read about our re-interpretation of published IR spectroscopy for alcohols. We show that when the peak with free ends is fitted with a 2-constant model, the spectra can be used to predict the activity coefficients.

We have developed an app to remove the detailed counting of fringes to determine pathlength in quantitative IR.

Bill Killian was recognized by with a 2nd-place award for the poster Leveraging Spectroscopy and Wertheim’s Theory for Modeling of Phase Equilibria.
Poster presented at the 2020 Dow-MSU Professional Development Day, June 24, 2020. This demonstrates how we are using spectroscopy to determine the fraction of hydroxyls free and for butanol the model shows that most hydrogen bonds species are linear.
