Mechanical properties of anhydrous oxalic acid and oxalic acid dihydrate. [PDF]
Physical Chemistry Chemical Physics, 2019 The mechanical properties of oxalic acid dihydrate and anhydrous oxalic acid (α and β polymorphic forms) were obtained by using rigorous theoretical solid-state methods based on density functional theory using plane waves and pseudopotentials.

2-Aminobenzoxazole–oxalic acid (2/1) [PDF]
IUCrDataIn the title compound, 2C7H7N2O+·C2O42−, proton transfer from oxalic acid to the N atom of the heterocycle has occurred to form a 2:1 molecular salt. In the extended structure, N—H...O hydrogen bonds link the components into [100] chains, which feature ...

Evaluation of oxalic acid extraction and quantification methods in the different purslane (Portulaca oleracea L.) matrices and spinach (Spinacea oleracea) [PDF]
MethodsXPurslane (Portulaca oleracea) and spinach (Spinacea oleracea) are species with elevated levels of oxalic acid, an antinutrient that interferes in the bioaccessibility of minerals such as calcium and iron.

Towards Sustainable Oxalic Acid from CO2 and Biomass
ChemSusChem, 2021 To quickly and drastically reduce CO2 emissions and meet our ambitions of a circular future, we need to develop carbon capture and storage (CCS) and carbon capture and utilization (CCU) to deal with the CO2 that we produce.

Improved Process for Separating TiO2 from an Oxalic-Acid Hydrothermal Leachate of Vanadium Slag
Metals, 2022 In the present study, a process of separating high-quality TiO2 from an oxalic-acid leachate of vanadium slag was proposed. It consists of two steps; oxalic acid was firstly recovered from the leachate by the cooling-crystallization method, and ...
