Chemical properties of oxalic acid, also known as oxalic acid, is widely present in foods of plant origin. Oxalic acid is a colorless columnar crystals, soluble in water but insoluble in ether and other organic solvents, oxalic acid, oxalate with a strong role in plant-derived foods is another type of metal chelating agents. When oxalic acid combined with a number of alkaline earth metal elements, which greatly reduces the solubility, such as calcium oxalate practically insoluble in water. Thus the presence of oxalic acid has to be Mineral Bioavailability of great influence; when the oxalic acid with some transition metal elements combine, as with the action of oxalic acid to form a soluble complex, greatly increasing its solubility [2]. The pharmaceutical industry for the manufacture of chlortetracycline, oxytetracycline, tetracycline, streptomycin, borneol, vitamin B12, phenobarbital and other drugs. Printing and dyeing industry as a color co-agent, bleach, pharmaceutical intermediates. Plastics used in the production of PVC, amino plastics, urea-formaldehyde plastic. [3] as a catalyst for the synthesis of phenolic resin, Dongguan oxalic acid, a catalytic reaction mild, Guangzhou oxalic acid, the process is relatively stable, the longest duration. Oxalic acid acetone solution which catalyze the curing reaction of the epoxy resin, the curing time is shortened. Also used as a urea-formaldehyde resin, melamine formaldehyde resin, pH adjusting agent. It may be added to the water-soluble polyvinyl formal adhesives in increasing the drying speed and bonding strength. Also used as a urea-formaldehyde resin curing agent, metal ion chelating agent. KMnO4 can be used as an oxidizing agent to produce starch adhesive accelerator, accelerate the oxidation rate, shorten the reaction time.
