Coalescence of bubbles in alcohol solutions has widespread industrial applications. This work presents studies on coalescence in aqueous solutions of pentanol, methyl isobutyl carbinol, hexanol, heptanol, and octanol. The effects of the alcohol concentration, hydrocarbon chain length, adsorption at the air-water interface, electrolyte, and intermolecular and surface forces on bubble coalescence were investigated. The origin of stability of the thin aqueous films was studied. The zeta potential at the air-water interface was measured in the presence of these alcohols and a 1:1 electrolyte. The charge at the interface decreased in the presence of alcohol. It was found that the electrostatic double layer force does not have any significant effect in the stability of these thin films. The major stabilization comes from the hydration force. In aqueous heptanol and octanol solutions, the hydrophobic force plays a vital role so that the stabilizing effect of these alcohols is partly incapacitated. The coalescence time data were compared with the predictions of seven film-drainage models. The coalescence time distributions were fitted by the stochastic model. The model parameters were analyzed with the physical properties of the systems.
