Yield:-

Reaction Conditions:

with dihydrogen peroxide;sodium sulfateReagent/catalyst;

Steps:

Epinephrine oxidation
An amount of 0.0400 g of Co(II)-Poly(EGDE-MAA-2MI) was suspended in 20 mL of 2 mM epinephrine and 46 mM H2O2 solution (higher concentrations of H2O2 were proved to be less effective). The medium of reaction was 0.1 M Na2SO4 solution. The absorbance of the solution was monitored as a function of time at 480 nm. For turbidity correction, the absorbance was measured at 700 nm and subtracted to the absorbance at 480 nm. A control experiment of epinephrine oxidation in homogeneous system was made with a solution of 2 mM epinephrine and 46 mM H2O2 in 0.1 M Na2SO4. Another control experiment was made with 0.0400 g of Co(II)-Poly(EGDE-MAA-2MI) suspended in 20 mL of 2 mM epinephrine and 0.1 M Na2SO4, in absence of H2O2. This experiment was repeated with previous and continuous bubbling of argon in the epinephrine solution, in order to displace the dissolved O2
