| Physical and Chemical Properties | Pale yellow crystalline powder. The melting point of 160 deg C (decomposition), the relative density of 2.28. Water of crystallization was lost at 142 °c under vacuum. Cold water solubility of 0.22g/100g, hot water in 0.026g/100g, soluble in cold salt solution. Preparation Method: from ammonium oxalate and ferrous sulfate reaction derived. First, ammonium oxalate and ferrous sulfate crystals were respectively dissolved in water and filtered. The ammonium oxalate solution was then added to the ferrous sulfate solution and stirred continuously in a stainless steel reaction pan to produce a pale yellow ferrous oxalate precipitate. After standing for 8-10H, the supernatant was separated, and the ferrous oxalate slurry was centrifuged, washed with hot water, and dried at 85-95 ° C., which was the finished product. Consumption of ammonium oxalate (content 450-500g/L)800kg, ferrous sulfate (95%)1560kg per ton of product. Uses: used as a photographic developer for the pharmaceutical industry. |
| Use | Used as analytical reagents and developers, as a new battery material for the production of lithium iron phosphate, but also for the pharmaceutical industry |
