A Calorimetric Technique for Determining Equilibrium Liquid-Phase Concentrations of Concentrated Species that React Reversibly

Abstract

A Calorimetric Technique is Presented to Estimate the Equilibrium Concentrations of Species Which Participate in Reversible Liquid-Phase Chemical Reactions. the Technique Relies on the Determination of that Particular Concentration of Reactant-Solvent Mixture Which When Injected into a Reaction Mixture at Equilibrium Produces No Reaption, and Thus No Reaction Heat Effect. This Injected Concentration, Called the "Null-Reactive Concentration", Allows Direct Determination of the Concentrations of the Species in the Equilibrium Mixture. It is Direct in the Sense that Determination of the Heat of Reaction and Equilibrium Constant as Parameters in a Model is Not a Necessary Intermediate Step. the Technique is Demonstrated with the Diels-Alder Reaction between Maleic Anhydride and 2-Methylfuran in P-Dioxane at 45 °C. at 45 °C, the Half-Life of This Reaction is Approximately 5 Min. the Estimated Uncertainty in Equilibrium Concentrations for the Reaction Studied is ±5%. © 1985, American Chemical Society.
