EDTA—Ethylenediaminetetraacetic Acid

1992
EDTA is used at low levels in some fabric washing powders as a bleach stabiliser. It is also used in soaps as a stabiliser and in some liquid products to enhance the action of preservatives. EDTA has, however, many other industrial applications and its use in detergents accounts for only approximately 20% of the total use.

COMPLEXES OF ETHYLENEDIAMINETETRAACETIC ACID WITH AMINES. MOLECULAR STRUCTURES OF BIS(MONOETHANOLAMINIUM) ETHYLENEDIAMINETETRAACETATE AND BIS[TRIS(HYDROXYMETHYL)METHYLAMINIUM] ETHYLENEDIAMINETETRAACETATE TRIHYDRATE

Кристаллография, 2023
Tetrabasic ethylenediaminetetraacetic acid H4L binds two molecules of monobasic amines to give the corresponding salts: ethylenediaminetetraacetates of bis(monoethanolaminium) H2L2–⋅2+H3NCH2CH2ОН, tris(hydroxymethyl)methylaminium H2L2–⋅2+H3NС(CH2ОН)3⋅3H2О, diethylaminium H2L2–⋅2+H2N(C2H5)2⋅H2О, tert-butylaminium H2L2–⋅2+H3NС(CH3)3⋅5H2О, and ...

The separation of plant cells with ethylenediaminetetraacetic acid

Experimental Cell Research, 1960
Abstract The ability of ethylenediaminetetraacetic acid (EDTA) to separate the cortical cells of the apple fruit has been studied. Macerating activity was influenced markedly by pH, temperature and concentration of the reagent. Procedures suitable for macerating plant tissues are described.

Safety and efficacy of ethylenediaminetetraacetic acid for removing microcapsules

Journal of Surgical Research, 2013
Microencapsulated islets are used to prevent immune rejection associated with pancreatic islet transplantation, but cellular overgrowth affects transplantation success, necessitating removal of microcapsules prior to retransplantation. This study aimed to investigate the safety and efficacy of ethylendiaminetetraacetic acid (EDTA) for the removal of ...

Effects of Ethylenediaminetetraacetic Acid (EDTA) on Prothrombin Consumption

Journal of Pharmaceutical Sciences, 1961
Abstract Whole human blood was treated with varying concentrations of ethylenediaminetetraacetic acid to determine the effect upon prothrombin consumption. The prothrombin consumption test was combined with the Dreskin two-stage prothrombin test to determine residual prothrombin as a function of incubation time.

SODIUM CHELATES OF ETHYLENEDIAMINETETRAACETIC ACID

Canadian Journal of Chemistry, 1963
The stability constant of the sodium chelate of EDTA was determined by means of a sodium-sensitive glass electrode. It appears that a hydrogen chelate of the formula NaHY2− is formed in the neutral solution of EDTA, but is very unstable. The stability constants, pKNaY = −2.61 and pKNaHY = 0.03, are comparable to the value obtained by Schwarzenbach and

Tungsten(V) complexes of ethylenediaminetetraacetic acid

Journal of Inorganic and Nuclear Chemistry, 1974
Abstract The complexes of pentavalent tungsten with EDTA were synthesized and characterized as salts of the complex anion, [W2O4Y]2−. The remarkable stability of this anion in aqueous solution (log β = 29·1) as well as the properties of the solid salts are in accordance with the proposed structure consisting of the binuclear unit, , surrounded ...

The effect of ethylenediaminetetraacetic acid on yeast cell membranes

Protoplasma, 1974
The influence of ethylenediaminetetraacetic acid on three yeast species was examined. EDTA causes leakage of cell constituents from protoplasts and whole cells of one of them whereas the other ones were resistant. Comparison of the membrane compositions suggested, that the relative amount of phospholipids as compared to total lipid determines for an ...

A mass spectral investigation of ethylenediaminetetraacetic acid

European Journal of Mass Spectrometry, 1995
Mass spectra of ethylenediaminetetraacetic acid (EDTA) were obtained using electron ionization (EI), chemical ionization (CI) and fast atom bombardment (FAB). Thermal degradation was observed in both EI and CI. It was nevertheless possible to obtain reproducible spectra and characteristic peaks at 125C probe temperature.
