Abstract :
The ionization of six compounds of bis-phenolic amides was studied spectrophotochemically in DMF–water mixture. The compounds showed two pKa values in the range of 5.97–7.32 for pKa1 and 7.61–8.44 for pKa2. The obtained values of Ka were normalized using the distribution diagrams of the different species and found to be in the range of 5.81–7.42 for pKa1 and 7.48–8.27 for pKa2.
