摘要: Thermodynamic and kinetic properties of the tautomerism of an indoline spiropyran in compressed CO2-ethanol mixture were studied by UV-Vis spectroscopy at 298.15 K, 303.15 K, and 308.15 K. It was found that the composition of the mixture affects the equilibrium constant and the rate constant significantly.
