Fig. 4. Effect of initial solution concentration of reagents on the acceleration factor for the hydrazone formation reaction in eqn (2). Droplets of initial size d0 = 1000 nm with methanol as the solvent are considered. Initial concentration in the droplets is between 100 mM (dark blue) and 0.01 mM (light blue). (a) Temporal evolution of the concentration of reagents (isatin and phenyl hydrazine). (b) Acceleration factor calculated as the ratio of the product formed in droplets and for the same reaction (with the same reagent concentrations) in a bulk solution. The vertical dashed line indicates when the evaporation of methanol is complete.
