Molecular Insight, through IR Spectroscopy, on Solvating Phenomena Occurring in CO₂‐Expanded Solutions

Abstract

Solvation power of CO2-expanded solvents: Mid-IR spectroscopy is used in CO2-expanded solvents (see graphic) to investigate the molecular interaction between solute and solvent functional groups responsible for the differential solubility behaviour of acetaminophen, an analgesic drug, in “CO2-expanded ethanol” and “CO2-expanded acetone”.
