Oxalic acid is an organic compound with the chemical formula H₂C₂O₄. It is a metabolite of organisms and is a medium-strong acid. It is widely distributed in plants, animals and fungi, and plays different functions in different organisms. Since oxalic acid can reduce the bioavailability of mineral elements and easily form calcium oxalate with calcium ions in the human body, leading to kidney stones, oxalic acid is often considered an antagonist for the absorption and utilization of mineral elements.
Product Application
Complexing agent, masking agent, precipitating agent, reducing agent. In analysis, it is used to verify and determine metal ions such as beryllium, calcium, chromium, gold, manganese, strontium, and thorium. Microcrystalline analysis examines sodium and other elements. Precipitates calcium, magnesium, thorium and rare earth elements. Standard solutions for calibrating potassium permanganate and cerium sulfate solutions. bleach. Dyeing aid. It can also be used to remove rust from clothes. In the construction industry, before painting exterior wall paint, because the wall is highly alkaline, oxalic acid should be applied first to remove alkali.
The pharmaceutical industry is used to manufacture chlortetracycline, oxytetracycline, tetracycline, streptomycin, borneol, vitamin B12, phenobarbital and other drugs. In the printing and dyeing industry, it is used as color development aid, bleaching agent and pharmaceutical intermediate. The plastic industry is used to produce polyvinyl chloride, amino plastics, and urea-formaldehyde plastics.
Used as a catalyst for the synthesis of phenolic resin, the catalytic reaction is mild, the process is relatively stable, and the duration is the longest. Oxalic acid acetone solution can catalyze the curing reaction of epoxy resin and shorten the curing time. It is also used as a pH regulator for synthetic urea-formaldehyde resin and melamine formaldehyde resin. It can also be added to polyvinyl formal water-soluble adhesive to improve drying speed and bonding strength. It is also used as a curing agent and metal ion chelating agent for urea-formaldehyde resin. It can be used as an accelerator for the preparation of starch adhesives using KMnO4 oxidant to speed up the oxidation rate and shorten the reaction time.
Wear protective equipment: Please wear appropriate protective equipment before operation, such as gloves, protective glasses, etc. to prevent direct contact with skin and eyes.
Avoid inhalation: Oxalic acid has a pungent odor. Operations should be carried out in a well-ventilated environment to avoid prolonged inhalation.
Control the dosage: Control the dosage of oxalic acid according to the instructions or professional recommendations to avoid excessive use.
Avoid mixing with other chemicals: Do not mix oxalic acid with other chemicals to avoid chemical reactions.
Storage safety: Store oxalic acid in a dry, cool, ventilated place, away from fire and heat sources, and make sure the container is sealed.
Emergency treatment: If you are accidentally exposed to oxalic acid or leakage occurs, please rinse immediately with plenty of water and seek medical help.
