Inhibition of the Corrosion of Iron by Lead Azelate: I. Uptake and distribution of azelate and lead ions

British Corrosion Journal, 1976
AbstractImmersion tests have confirmed that, in the pH range 4·5–7·0, lead azelate is a more efficient inhibitor for iron than sodium azelate.It has been shown, by means of14C labelled lead azelate, that during inhibition azelate ions became firmly bound to the oxide covered iron surface, probably in the form of ferric azelate and, by means of 210pb ...

Syntheses and luminescent properties of a series of new lanthanide azelates

Dyes and Pigments, 2020
Abstract A series of new lanthanide azelates [Ln(aze)(Haze)(H2O)]·H2O {Ln = La (1a), Ce (1b), Pr (1c); H2aze = azelaic acid}, [Ln2(aze)3(phen)2]·H2O [Ln = Nd (2a), Er (2b); phen = 1,10-phenanthroline], [Sm(aze)(Haze)(phen)]·2H2O (3), [Gd(aze)(phen)2]·ClO4 (4) and (Hphen)[Tb2(aze)2(phen)4]·3ClO4 (5) were hydrothermally prepared and structurally ...

Groundwater geochemistry of Ain Azel area, Algeria

Geochemistry, 2014
Abstract Hydrogeochemical data for 18 groundwater samples and 11 hydrochemical parameters were subjected to Q- and R-mode cluster analysis and inverse geochemical modeling. Q-mode cluster analysis resulted in three distinct water types (brackish water type, saline water type and highly saline water type). R-mode cluster analysis led to the conclusion

Protection of iron powder by heavy-metal azelates

Soviet Powder Metallurgy and Metal Ceramics, 1966
1. A method is proposed for protecting iron powder against atmospheric corrosion by impregnating it with lead, zinc, calcium or barium azelate. 2. It was established that the protective effect of heavy-metal azelates is due to their hydrophobizing effect. 3.

Mechanism of Inhibition of Corrosion of Mild Steel in Aqueous Solutions of Sodium Azelate: II. Uptake and distribution of azelate ions on the surface of inhibited mild steel

British Corrosion Journal, 1972
AbstractThe uptake and distribution of azelate ions on the surface of mild steel, inhibited in solutions of sodium azelate over the pH range of 5 to 7, has been studied by means of radio-tracer techniques. It has been shown that azelate ions become firmly bound to the inhibited surface and that the extent of uptake is dependent on solution pH, being ...

Mechanism of Inhibition of Corrosion of Mild Steel in Aqueous Solutions of Sodium Azelate: I. Effect of solutions of sodium azelate on the air-formed oxide film on mild steel

British Corrosion Journal, 1972
AbstractChanges in the thickness and ferrous ion permeability of the air-formed oxide film on mild steel, immersed in solutions of sodium azelate, have been studied as functions of immersion time and solution pH. In neutral solutions, characteristic thickening of the air-formed oxide film takes place, whilst at lower pH values slight, but significant ...

Oscillatory structure–property correlation in azelate polyols and thermoplastic polyurethanes

Journal of Applied Polymer Science, 2018
ABSTRACTAzelate polyols of 2000 g mol−1 have been successfully prepared via esterification of renewable azelaic acid with linear diols containing different number of CH2 repeating units. Structure–property correlation of the azelate polyols had been evaluated in thermoplastic polyurethanes (TPUs).

Neopenthyl glycol containing poly(propylene azelate)s: Synthesis and thermal properties

European Polymer Journal, 2007
Poly(neopenthyl azelate) (PNAz) and poly(propylene/neopenthyl azelate) random copolymers (PPAz-PNAz) (NAz unit content from 5 to 20 mol%) were synthesized and characterized in terms of chemical structure and molecular weight. Afterwards, the polyesters were examined by TGA, DSC and X-ray diffractometry. Good thermal stability was found for each sample.

Chronic oral toxicity studies of di-n-hexyl azelate in rats and dogs

Toxicology and Applied Pharmacology, 1962
Abstract Groups comprising 35 male and 35 female rats were maintained for two years on diets containing O (control groups), 0.1, 0.5, and 15% DnHA. Growth was retarded in the groups given the 15% diets, otherwise all groups grew normally. Food consumptions were normal.
