AZChEThe process of heterogenizing homogeneous Co3+ ion as catalyst for the liquid-phase oxidation of acetaldehyde to form peracetic acid was developed and studied. The reaction mechanism of acetaldehyde oxidation was proposed and the ratedetermining steps were experimentally identified. The results indicated that the selectivity of producing peroxides is very high and the decompositions of peroxides to form the side product, acetic acid, are insignificant. The rates of formation of peracetic acid obtained by using supported homogeneous Co3+ ion as a catalyst were different from those with homogeneous Co3+ ion as a catalyst.
A generalized corresponding states prinicple (GCSP) based on the properties of two (nonspherical) reference fluidsis extended here to dlffusion coefficients. The prediction of selfdiffusion coefficients requires a knowledge of the selfdiffusion coefflcients of two (similar) fluids, whereas the prediction of infinite dilution diffusion coefficients in a given solvent requires a knowledge of the infinite dilution diffusion coefficients of two fluids in the same solvent. The composition dependence of binary diffusion coefflcients can be correlated by using the measured (or predicted) infinite dilution diffusion coefficients. Good agreement between experiment and calculation has been obtained by using, at most, one adjustable constant to characterize each binary system. The new method is as good as, and often better than, the commonly available predictive equations.
