The Oxidation of Aldehydes in Aqueous Solutions of Cetomacrogol

Abstract

The oxidation of emulsions and solutions of five paraffinic aldehydes in aqueous solutions of cetomacrogol was measured manometrically at 25°. The rate of oxidation depends on the saturation of the dispersion and not on the concentrations of aldehyde and cetomacrogol except in so far as these control saturation. A method of expressing saturation, applicable to both solutions and emulsions is proposed. Differences between the oxidation rates of emulsions containing aldehydes of different chain length are shown to depend mainly on the proportion of aldehyde in the disperse phase.
