Sažetak
The well-known Koutecky's equation cannot be used to describe the polarographic kinetic currents of acetaldehyde in aqueous solutions since the diffusion contribution of the depolarizer from the bulk solution is not considered. The rate constants of dehydration reaction of acetaldehyde hydrate derived from Koutecky’s equations are larger as compared with the data obtained by other (non-polarographic) methods. Koutecky's equation modified by us taking into account the diffusion contribution of the depolarizer from the bulk solution allows one to obtain the rate constants of the dehydration of acetaldehyde hydrate close to the ones found by non-polarographic methods.
In addition, we present a detailed consideration and analysis of the equilibrium constants of the hydration reaction of acetaldehyde found by different methods in order to choose the most reliable constant for kinetic calculations.
