An automatic single-liquid-slug oscillatory flow platform was
established for the kinetic investigation of photochemical reactions.
Reaction parameters including concentration, reaction time, light
intensity, pressure, and temperature were controlled precisely in an
automatic manner, and the reaction outcomes were obtained accurately
via, integration of an online HPLC. With the reaction kinetics
measurement performed for the photocatalytic oxidation of citronellol by
Ru(bpy)3Cl2 at a volume scale of 50 µL, it was demonstrated that the
single-liquid-slug oscillatory flow method was capable of achieving
material and time savings of 70% and 38% respectively as compared to the
conventional batch method, and of 80% and 62% respectively as compared
to the continuous flow method. The four reaction orders manifesting the
effects of the substrate concentration, photocatalyst concentration,
light intensity, and oxygen pressure, respectively, were attained as
well as the photoreaction rate constant. Furthermore, the kinetic data
obtained under a series of temperatures also shed light on the
photoreaction mechanism which exhibited a relationship between the
photoreaction rate constant and temperature that deviated from the
Arrhenius law. The approach developed in this work is especially useful
for the kinetic studies of photoreactions with relatively slower
intrinsic reaction kinetics, achieving a more resource-efficient
practice with higher repeatability and accuracy.
