Abstract

The ionization constants for an unusual keto ester were determined by examination of the complex visible-UV absorption spectra of the monobasic salt. Interpretation of changes with pH of the spectra at four different wave lengths required an estimate of 12 molar absorbancies and two ionization constants. A computer program permitted progressive selection of best values. The ratio of K1 to K2 for this acid is exceptionally high and exceeds that for any other acid for which we have found data.
