Composition of antimony pentoxide
The antimony pentoxide is the white or yellow powder. Not insoluble in water, soluble in hot hydrochloric acid. Used for the manufacture of antimonates and other antimony compounds. The antimony pentoxide is produced by antimony or antimony trioxide and concentrated nitric acid reaction.
Soluble in strong base antimoniate. Loss of oxygen and generate tetroxide antimony at 380 ℃, lose oxygen and generate antimony trioxide at 930 ℃.
Function and use
Mainly used for the manufacturing antimonate, antimony glycolate and various other antimony compounds, which can also be used for the manufacture of catalyst in chemical production.
Overview of the risk:
Health hazards: It has a stimulating effect on the mucous membrane, which can cause damage to internal organs. Acute poisoning: exposure to high concentrations can cause chemical conjunctivitis, rhinitis, pharyngitis, laryngitis, bronchitis, pneumonia. Oral suck cause gastroenteritis. Systemic symptoms are fatigue, weakness, dizziness, headache, limb muscle aches, and can cause heart, liver and kidney damage. Chronic effects: often appear headache, dizziness, excitable, insomnia, fatigue, gastrointestinal disorders, mucous membrane irritation, and can cause perforation of the nasal septum. It has stimulus and sensitization for the skin. It can cause antimony pneumoconiosis in antimony smelting process.
Explosion Hazard: This product is flammable, toxic, irritant.
First aid measures:
Skin contact: Remove contaminated clothing, use soap and water to thoroughly wash the skin.
Eye contact: Lift the eyelid, wash with mobile or saline rinse and seek medical advice
Inhalation: rapidly leave from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing has stopped, carry out artificial respiration immediately and have medical treatment.
Ingestion: drink enough water, induce vomiting. Carry out gastric lavage and have medical treatment.
Handling and storage:
Handling Precautions: closed operation, local exhaust ventilation. The operator must go through specialized training, strict adhere to rules. It is proposed that operators wear filter and dust proof respirators, wear chemical safety glasses, and the penetrative gas-protective clothing, wear chemical resistant gloves to avoid dust. Avoid contact with reducing agents, acids. Lightly load and lightly unloading, to prevent damage packaging and containers. Equipped with spill response equipment. Empty containers may have harmful residues.
Storage: Store in a cool, ventilated warehouse. Keep away from fire and heat. Sealed packaging. Store separately with reducing agents, acids, food chemicals and avoid mixing reservoir. Storage areas should be equipped with suitable material host spill.
