The main raw material for all oxalates is Oxalic Acid. Oxalic Acid can be prepared by the oxidation of carbohydrates or glucose in the presence of Nitric Acid, using Vanadium Pentoxide as a catalyst. It can also be prepared by heating sodium formate with an alkali catalyst to form Antimony Potassium Oxalate, which can be converted to free oxalic acid when treated with Sulphuric acid. Today, Oxalic Acid is commercially prepared from the molasses route from sugarcane syrup. Antimony Potassium Oxalate is produced by a reaction between Antimony Oxide and Oxalic Acid in the presence of Potassium Hydroxide.
