The solid product was brown crystals. The melting point is about 37 °c; The relative density is 1. 82. In the air is very easy to absorb moisture and deliquescence. The liquid product was a red-brown solution. Soluble in water, ethanol, glycerol, ether and acetone, difficult to dissolve in benzene.
iron filings or iron powder and hydrochloric acid were used as raw materials. After the reaction was completed, the crystals were cooled and crystallized to precipitate Brown yellow granular ferric chloride crystals.
used as a flocculant in drinking water and industrial water purification treatment. It has good solubility and excellent flocculation effect. Can be used for activated sludge dewatering. The pH range used was 6. 0-11.0, and the optimal pH range was 6. 0-8.4. The usual amount is 5 to 10 mg/L. The floc formed is coarse, the precipitation speed is fast, and it is not affected by temperature. It is used to treat wastewater with high turbidity, and the effect is more significant. The corrosion of ferric chloride is stronger than that of ferrous sulfate, and the equipment needs to be treated with anti-corrosion. When it dissolves in water, hydrogen chloride gas is produced, polluting the surrounding environment. In addition, ferric chloride can also be used as waterproofing agent, printing plate etchant, dye industry oxidants and mordant, organic synthesis of catalysts and the manufacture of other iron salts.
non-flammable, corrosive, can stimulate the skin, eyes. Inhalation can cause sore throat, Abdominal Pain, Diarrhea, Nausea, etc. Staff should be protected. After ingestion, the application of water to clean the mouth, drink milk. The production workshop should be well ventilated and the equipment should be sealed. In the storage and transportation, strict protection against toxic substances pollution, rain and moisture.
