Optical fiber-based on-line UV/Vis spectroscopic monitoring of chemical reaction kinetics under high pressure in a capillary microreactor

Article abstract of DOI:10.1039/b500429b

With a miniaturized (3 μL volume) fiber-optics based system for on-line measurement by UV/Vis spectroscopy, the reaction rate constants (at different pressures) and the activation volumes (ΔV^≠) were determinined for a nucleophilic aromatic substitution and an aza Diels-Alder reaction in a capillary microreactor.
