Ph of catechol

WebbCatechol, a major mussel-inspired underwater adhesive moiety, has been used to develop functional adhesive hydrogels for biomedical applications. However, oxidative catechol chemistry for interpolymer crosslinking and adhesion is exclusively effective under alkaline conditions, with limited applications in non-alkaline conditions. 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.
