“…Additionally, the peaks at around 1160, 1290, 2240, 3228 and 3540 cm −1 for HDDPA almost disappeared. These changes suggested that the P=O and -P-OH groups might react with Zn 2+ and the previously existed O-H and P=O bonds might be broken (P=O was changed to P-O), which was consistent with previous reports that the oxygen atoms in both of P=O and -P-OH groups could combine with zinc atoms [36,37,46,47].…”

“…Figure 9b illustrated that the P 2p XPS bands occurred at around 134.15 eV for HDDPA, 133.70 eV for the Zn-HDDPA precipitate and 133.46 eV for HDDPA adsorbed on hemimorphite surfaces, which elucidated that after HDDPA reaction with Zn ions or adsorption on hemimorphite surfaces, the P 2p binding energy decreased, suggesting that HDDPA might chemisorb on to hemimorphite surfaces to increase the electron density around the P atom [50]. The increased binding energy for Zn 2p 3/2 and the reduced for P 2p confirmed that the Zn(II)-HDDPA surface complexes might be formed on hemimorphite [46,47].…”

“…The results elucidated that the atomic proportion of carbon, oxygen and phosphorus in HDDPA was in accordance with its molecular composition of C12H28P2O7. For the Zn-HDDPA precipitate, the atomic ratio of phosphorus to zinc was 1.17:1, inferring that the configuration of the Zn-HDDPA precipitate might be (HDDPA)Zn2 [46,47]. After HDDPA treatment, the atomic concentrations of carbon and phosphorus on hemimorphite surfaces increased and those of oxygen, silicon and zinc decreased, confirming the adsorption of HDDPA on hemimorphite.…”

“…The P 2p and Zn 2p 3/2 XPS gave clear evidence that HDDPA anchored on hemimorphite surfaces by chemisorption. Thus, Zn(II)-HDDPA surface complexes might be formed on hemimorphite [46,47], which hydrophobized hemimorphite particles to be floated out in froth flotation.…”

Hemimorphite Flotation with 1-hydroxydodecylidene-1,1-diphosphonic acid and Its Mechanism

1-hydroxydodecylidene-1,1-diphosphonic acid (HDDPA) was prepared and first applied in flotation of hemimorphite. HDDPA exhibited superior flotation performances for recovery of hemimorphite in comparison with lauric acid, and it also possessed good selectivity against quartz flotation under pH 7.0-11.0. Contact angle results revealed that HDDPA preferred to attach on hemimorphite rather than quartz and promoted the hydrophobicity of hemimorphite surfaces. In the presence of HDDPA anions, the zeta potential of hemimorphite particles shifted to more negative value even if hemimorphite was negatively charged, inferring a strong chemisorption of hemimorphite to HDDPA. The Fourier transform infrared (FTIR) recommended that HDDPA might anchor on hemimorphite surfaces through bonding the oxygen atoms of its P(=O)-O groups with surface Zn(II) atoms. X-ray photoelectron spectroscopy (XPS) gave additional evidence that the Zn(II)-HDDPA surface complexes were formed on hemimorphite.

A new zinc aminophosphonate corrosion inhibitor (ZnATMP) containing the Zn–N bond in the coordination environment of zinc has been synthesized, separated and studied. The inhibition coefficient according to the all‐Union State Standard 9.502 is 14.7. The interaction of the metal‐coordination corrosion inhibitor ZnATMP with the surface of carbon steel has been studied by X‐ray photoelectron spectroscopy. The structure of the protective layer, its stability in the temperature range of 300–575 K and the mechanism of thermal destruction have been investigated. It is shown that the interaction of the nitrogen‐containing chelate corrosion inhibitor with the steel surface leads to the formation of the surface protective layer, the atoms of which form strong covalent bonds Fe–O–P–Zn–N(C). Fe atoms pass into a high‐spin state. Thermal action on the protective film results in its destruction at 575 K. Copyright © 2014 John Wiley & Sons, Ltd.

Organophosphonate zincate corrosion inhibitor (CCDC 919565) contains the Zn-N bond closing three fivemembered chelate rings with the formation of a common bonding electronic subsystem of N-Zn-O-P atoms. Zinc is coordinated in a distorted trigonal bipyramidal configuration involving the oxygen atom of the neighboring molecule of the complex. Space group 1 P , Z = 2, a = 11.2208 (2) Å, b = 11.2666(3) Å, c = 12.3286(3) Å, α = 108.455(2)°, β = 97.168(2)°, γ = 117.103(2)°. The inhibitor does not form polymeric structures, provides the stability and reproducibility of technological quality parameters. The initial decomposition temperature is 250 °C.
