Calcium Oxalate is a derivative of Oxalic Acid. Calcium Oxalate is practically insoluble in water and converts to the oxide when heated (calcined). Calcium Oxalate is a White odourless powder. Calcium Oxalate decomposes at the temperatures above 200oC. It should be stored in tightly closed containers in a Room Temperature.
Synthesis / Manufacturing Process of Oxalates
The major raw material to all the Oxalates is Oxalic Acid. Oxalic Acid can be prepared by oxidation of Carbohydrates or Glucose in presence of Nitric Acid & using Vanadium Pentoxide as a Catalyst. It can be also prepared by heating sodium formate in the presence of an alkali catalyst to form Calcium Oxalate, which can be converted to free oxalic acid when treated with Sulphuric acid. However today Oxalic Acid is commercially prepared from Molasses route from cane molasses or sugarcane syrup.
Calcium Oxalate is produced by reaction between Calcium Carbonate & Oxalic Acid.
