Webb8 dec. 2016 · Therefore, pH is an essential parameter. In our case, since the pKa of PA is 10.71, we maintained the pH of the reaction medium around 11 using 10 mM aqueous sodium carbonate solution as the solvent. Secondly, at high pH, as reported, the reaction rate of catechol oxidation is the rate-determining step that affects further reactions.
