The association constants, kd, of dichloroacetic acid (DCA) with ethers (tetrahydrofuran, tetrahydropyran, dibutyl ether, 1, 4-dioxane) were measured in CCl4 from 20°–40° using near IR spectra. A linear relationship between log10KD and log10Kp was found, where Kp was the association constant of phenol with ethers. On the basis of their relationship the association constants of DCA with propylene oxide (PO) were estimated from those of ...
