In 1970, W. L. Masterton and T. P. Lee applied the scaled particle theory to nonpolar solute system, and drived an applicable formula of salting-out con- stant. This work has tried to apply the scaled particle theory to polar solute system, and drived a formula of salting-out constant for polar nonelectrolyte.
The k_s values of CH_3COOH, n-CH_3CH_2COOH, n-CH_3(CH_2)_2COOH, n-CH_3(CH_2)_4-COOH, and n-CH_3(CH_2)_5COOH in four small ion aqueous salt solutions were calcu- lated. The modified formula gave the results in better agreement with the experiment than the original formula.
