Mediated Electrochemical Oxidation

A diethyl phosphite mediated electrochemical oxidation strategy for the synthesis of 3,4-dihydroisoquinolin-1(2H)-ones from tetrahydroisoquinolines under mild conditions has been developed. This protocol provides an environmentally friendly and simple way for the construction of C=O bonds in an undivided cell unit.

Dihydropyridine Derivatives

Electrochemical oxidation of 1,4-dihydropyridines I-XII and electrochemical reduction of the nitro group of 4-(2-nitrophenyl)-1,4-dihydropyridines III, VI, IX and XII was studied using cyclic voltametry. When comparing the electrochemical and the biological oxidation of 3,5-dimethoxycarbonyl-2,6-dimethyl-4-(2-nitrophenyl)-1,4-dihydropyridine (IX, Nifedipine) and related 1,4-dihydropyridines it was found that in spite of certain common trends the oxidation of these compounds (I-XII) in the organism cannot be predicted unambiguously. Of the substances tested compounds IX and XI (3,5-diethoxycarbonyl-4-phenyl-2,6-dimethyl-1,4-dihydropyridine) were the least oxidizable by the respiratory chain, and at the same time they did not inhibit this enzyme system. In addition to this, compound IX was the least oxidizable by the microsomal system.

Simulated Wastewater

The removal of ammonia nitrogen in simulated wastewater with 90mg/L NH4Cl was researched by ammonia stripping, electrochemical oxidation and the combination of the ammonia stripping and electrochemical oxidation. It is shown that the reduction of ammonia is enlarged with increasing of wastewater’s alkalinity during stripping. And the removal rates of ammonia nitrogen are 2.1% at pH2 and 43.1% at pH7 which is not related to the stripping time. The ammonia removal is higher efficiency in pH12 which is in the range of 45.1% and 61.4% when the stripping time is changed from 40 to 100 min. The removal rate of ammonia nitrogen is increased with the extension of electrolysis time by the way of the electrochemical oxidation. For 100min electrolysis, the ammonia removal in the cathodic and anodic compartments are 55.8% and 86.9%, respectively. Moreover, by using the ammonia stripping and electrochemical oxidation simultaneously, the ammonia removal in the cathodic and anodic compartments are up to 91.8% and 99.8% for 100min, respectively. The combining of the ammonia stripping with electrochemical oxidation technology has obviously synergistic effect in purifying ammonia nitrogen wastewater.
