Another method of obtaining oxalic acid is by passing carbon dioxide over metallic sodium or potassium at 360 °C, or by oxidizing ethylene glycol or other organic compounds (e.g., sugars) with nitric acid. It can also be obtained through the reaction of acetylene with potassium permanganate. This compound is soluble in both water and organic solvents like ethanol and diethyl ether. When dissolved in water, it forms a dihydrate and can also form salts and hydro-salts known as oxalates.
Oxalic acid finds wide applications across various industries and is particularly useful in beekeeping. It is an excellent rust remover and is commonly used in GRP/fiberglass cleaners. At our factory, we provide oxalic acid in its purest form, with a purity of 99.5%. If necessary, it can be converted into an oxalic acid solution with the appropriate concentration. The following examples illustrate different concentrations and their applications.
To prepare an oxalic acid solution for rust removal, mix it within the range of 10 to 20% concentration. Add oxalic acid to warm water and stir until the crystals dissolve completely. Using warm water facilitates the mixing process. For a 10% concentration solution, mix 100g of oxalic acid with 900ml of warm water for every liter of solution.
The solution is now ready for immediate application on rusted objects. We recommend leaving the objects in the solution for several hours, depending on the extent of rusting.
In our store, you can find a ready-to-use solution of 5% oxalic acid.
Oxalic acid is highly effective as a wood bleach. We recommend preparing a 10% solution using warm water. Apply the bleach to the wood using a brush, and once it dries, you can clean the wood before proceeding with varnishing or other treatments.
Preparing the wood before applying oxalic acid is crucial. The solution needs to penetrate the wood, so sanding the surface beforehand is necessary.
We offer a pre-made wood bleach containing oxalic acid in our store.
Oxalic acid is the primary recommended treatment for varroa mites by the European Specialist Group, which developed a year-round method for combating varroa in 1998.
Dissolve 400g of sugar in 400g of warm water, then add 30g of acid. Mix the solution thoroughly with a plastic spoon. This will yield approximately 600ml of solution. It is essential to maintain these proportions, and we do not recommend altering the concentration.
Lift the covers or remove the bars, lightly smoke the bees, and pour a thin stream of warm solution over them, using 5ml per street. Proportions:
Administer the solution using a plastic syringe without a needle or a dispenser.
When working with oxalic acid, remember to wear protective eyewear and rubber or latex gloves.
Polylactic acid, commonly referred to as PLA, is a renewable and organic thermoplastic monomer derived from sources like corn starch or sugar cane. Unlike most plastics that are produced from fossil fuels through petroleum distillation and polymerization, PLA production utilizes biomass resources.
Sodium dichloroisocyanurate, derived from chlorinated hydroxy triazine, is a sodium salt widely utilized as a source of chlorine, specifically in the form of hypochlorous acid, for water disinfection purposes.
Propylene carbonate is a petroleum-derived ingredient used in skincare and cosmetics. It acts as a solvent, dissolving other ingredients, and helps adjust the thickness of formulations. It enhances product texture and spreadability. Propylene carbonate has been deemed safe for use in cosmetics at concentrations typically used, according to safety assessments.
