  • Description

    Oxalic acid is a metabolic product of organisms, which is widely distributed in plants, animals and fungi, and play different functions in different organisms. The study found that more than 100 kinds of plants rich in oxalic acid, especially the content of spinach, amaranth, sugar beet, purslane, taro, sweet potato and rhubarb plants in the highest, because of oxalic acid can reduce the bioavailability of mineral elements in the human body, easy to form calcium oxalate and calcium oxalate cause kidney stones, so is often considered an antagonist the mineral elements absorption and utilization.

    ECHEMI Editorial Reference
    Oxalic acid dihydrate occurs as colorless crystals or a white crystalline powder; it is odorless. It sublimes at 150–160 °C and effloresces in warm, dry air. One gram is soluble in 7 mL of water, 2 mL of boiling water, 2.5 mL of ethanol, 1.8 mL of boiling ethanol, 100 mL of diethyl ether, and 5.5 mL of glycerol; it is insoluble in benzene, chloroform, and petroleum ether. The pH of a 0.1 mol/L solution is 1.3. It has low toxicity; (rabbit, dermal) is 2000 mg/kg.
    Oxalic acid dihydrate (OAD) which has very high initial phase transition enthalpy is a promising phase change material (PCM). This compound is low manufacturing cost and wide usage. In OAD, alternating acid and water molecules that act both as hydrogen-bond donors and acceptors. OAD needs a lot of energy to break the hydrogen-bond in the melting process. Therefore, OAD has a very high heat of fusion of 370 J·g-1,which is a very promising PCM in TES for applications such as industrial waste heat recovery or solar energy storage systems[1].
    Oxalic acid dihydrate (OAD) crystals are reported to be monoclinic withP21/nspace group. The electron density of OAD has been obtained using X-ray diffraction studies under high resolution.
    Crystallise oxalic acid from distilled water. Dry it in a vacuum over H2SO4. The anhydrous acid can be obtained by drying at 100o overnight. [Beilstein 2 IV 1819.]

    Reactivity Profile:

    At high temperatures oxalic acid decomposes, producing toxic carbon monoxide, andformic acid. Mixing with warm sulfuric acidmay produce the same products: CO2, CO,and formic acid. It reacts with many silvercompounds, forming explosive silver oxalate(NFPA 1986). An explosion occurred whenwater was added to an oxalic acid/sodiumchlorite mixture in a stainless steel beaker.There was also evolution of highly toxicchlorine dioxide gas (MCA 1962). Oxalicacid reacts violently with strong oxidizingsubstances.

    Critical Temperature & Pressure:

    Store at +5°C to +30°C.
