Abstract: Apparatus and process for removing and/or converting contaminants in water-miscible organic solvent mixtures by surface interaction effects to forms less objectionable with lesser metabolic impacts for humans. The process both changes distillation entrapped contaminant compounds in-situ and effects removal of the compounds and their reaction products. In what follows, water-miscible-organic-solvent and water mixtures can be substituted for alcohols. The alcohol to be treated is placed in a ventilated vessel leaving room for head space. Contaminant free air or a specific organic-contaminant-free gas is injected into or otherwise placed in contact with the alcohol. A vacuum is pulled within the vessel, which draws the gas through the alcohol into the head space creating gas bubbles. Energy within a specified range of frequencies is imparted to the fluid causing cavitation and reaction.
