Dissociation constants and reactions of 3-phenyl and 3-cyclohexyl-2-mercaptopropenoic and 3-phenyl-2-mercaptopropanoic acids.
The dissociation constants of 3-phenyl- and 3-cyclohexyl-2-mercaptopropenoic acids have been determined spectrophotometrically (I = 0.01M) in aqueous medium, and potentiometrically for both reagents and for 3-phenyl-2-mercaptopropanoic acid in water-ethanol medium. The analytical properties of the three compounds have been studied and also the compositions of some of their insoluble metal chelates.
