The distance of ∼ Å separating the carboxylic OH oxygen from the water oxygen atom in the αpolymorph of crystalline oxalic acid dihydrate is by ∼ Å shorter than the average distance in carboxylic acid monohydrates. It is also by ∼ Å shorter than the corresponding distance presently calculated for the heterotrimer consisting of one acid and two water molecules.
Oxalic acid is an organic compound with the formula C 2 H 2 O 4. It is a colorless crystalline solid that forms a colorless solution in water. Its condensed formula is HOOCCOOH, reflecting its classification as the simplest dicarboxylic acid. Its acid strength is much greater than that of acetic acid.

Oxalic acid is the chemical compound with the formula that can be written in a number of equivalent ways, C2O4H2, C2O2(OH)2, and as HOOCCOOH. This colourless solid is a dicarboxylic acid. In terms of acid strength, it is about 3, 000 times stronger than acetic acid. Its conjugate base, known as oxalate (C2O4 2), is a reducing

A bentonite from Milos, Greece, was activated with oxalic acid and the effect of acid activation conditions on bleaching of sunflower oil was investigated. The activation parameters studied were temperature, retention time and oxalic acid to bentonite mass ratio.
Treatment with both minerals and organic acid could remove both interlayer and structural iron and improve the whiteness with breaking up layered structure. However, sodium dithionite treatment is observed to be more suited to remove iron impurities from bentonite and improve whiteness to 11% without any effect on the structure of the clay.
Oxalic acid dihydrate (OAD) which has very high initial phase transition enthalpy is a promising phase change material (PCM). In this paper, shapestabilized composite PCMs composed of OAD and bentonite were prepared by a facile blending method to overcome the problem of leakage.
The lowest nitrate and nitrite accumulation rate was observed at urea fertilization on 50 days after planting and lack of bentonite application, whereas the lowest oxalic acid content was obtained at urea fertilization on 25 days after planting in a soil without bentonite application.
