Hydrogen migration in oxalic acid di-hydrate at high pressure?
Single crystal X-ray diffraction of oxalic acid dihydrate H(2)C(2)O(4).2H(2)O (1), at pressures up to 5.3 GPa, shows significant changes in the molecular geometries, probably accompanied by a proton migration from H(2)C(2)O(4) to H(2)O and formation of ionic species, as predicted by periodic DFT calculations.
متن کاملconsequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
13C chemical shielding in oxalic acid, oxalic acid dihydrate, and diammonium oxalate
13C chemical shielding tensors in three oxalates were investigated in order to determine the effe~ts of protonation and conformation changes on the tensor elements and their orientations. The expenmental results. together with those in the accompanying paper [R. G. Griffin and D. J. Ruben, J. Chern. ~hys. 63, 1272 (1975)], indicate that, while neither of these factors seems to seriously effect ...
متن کاملOrdered Nanoporous Alumina Membranes Formed in Oxalic/Phosphoric Acid Using Hard Anodization
Highly self-ordered alumina nanopore arrays were fabricated using hard anodization technique in different mixtures of oxalic/phosphoric acid. The phosphoric acid concentration was varied from 0.05 to 0.3 M while the oxalic acid concentration was changed between 0.3 and 0.4 M. The self ordered nanoporous arrays were obtained in anodization voltage changing from 130 to 200 V. The interpore distan...
متن کاملThe Metabolism of Oxalic Acid*
103 Abstract: Oxalic acid is a widely occurring natural product of animals, plants and other organisms. It sometimes occurs as a free acid, but more commonly as a calcium salt. Organisms exhibit various levels of oxalate content which even show fluctuations among the organs of the same individual. Although oxalate seems to engage in the metabolism and adaptation of animals, plants and fungi, it...
