Ferrous ethylenediaminetetraacetate

Hydrazine reduction of ferric ethylenediaminetetraacetate (denoted FeY ) gives nitrogen in high yield" In the absence of added phenanthroline the reaction, initially rapid, slows down and becomes second order in FeY . When ferrous ethylenediaminetetraacetate (FeY ) is initially present, the reaction is second-order in FeY throughout. In the presence of phenanthroline the order in FeY is one throughout. Under both sets of conditions the reaction is first-order in hydrazine. 

Until recent years the only syntheses of 3-hydroxy quinoline involved multistep processes, the last step of which consisted of the conversion of 3-aminoquinoline to 3-hydroxyquinoline via the diazonium salt. " Small quantities of quinoline have been oxidized to 3-hydroxyquinoline in low yields by using oxygen in the presence of ascorbic acid, ethylenediaminetetraacetic acid, ferrous sulfate, and i)hosi)halc buffer. The decarboxylation of 3-hydroxycinchoninic, acid in boiling nitrobenzene has been re-... 

The most important ferrous developers, however, are the complexes with ethylenediaminetetraacetic acid (EDTA) and related ligands, such as diethylenetriaminepentaacetic add (DTPA), nitrilotriacetic add (NT A) and JV-hydroxyethylethylenediaminetriacetic add (HETA). Complexes... 

Udenfriend et al developed a system for effecting aromatic hydroxylation consisting of ferrous sulfate, oxygen, ascorbic acid, and ethylenediaminetetraacetic acid (EDTA) in a phosphate buffer and noted that, in the cases tried, oxygen could be replaced by hydrogen peroxide in a nitrogen atmosphere. EOT A is not essential but greatly increases the reaction rate. Dihydroxymaleic acid and diethyl diketosuccinate were about as active as ascorbic acid alloxan and ninhydrin were less active. Examples ...

CEC [Chisso Engineering Company] A process for removing oxides of nitrogen from flue gases by scrubbing with an aqueous solution containing ferrous ion and ethylenediaminetetraacetic acid (EDTA). An iron nitrosyl compound is formed. Developed by Chisso Engineering Company, Japan, and piloted in France and Japan. 

In the course of a study of the conversion of tyramine to hydroxy-tyramine by adrenal medullary homogenates, Udenfriend and his co-workers (106,769) observed t t nonspecific nonenzymic hydroxylation occurs in the presence of oxygen, ascorbic acid, ferrous iron, and ethylenediaminetetraacetic acid. The products obtained from a number of aromatic compounds are mmilar to those formed in intact animals (769) (Table VII compare Table XI).. ...
