|Product name||phosphoric acid|
1. Stable under normal temperature and pressure
2. Materials to avoid Air Moisture/moisture crystals with garlic smell. Soluble in water and alcohol. Corrosive and can cause burns. Irritating to skin. Soluble in water and alcohol. It is slowly oxidized into orthophosphoric acid in the air, and decomposed into orthophosphoric acid and phosphine (highly toxic) when heated to 180 °C. Phosphorous acid is a dibasic acid, and its acidity is slightly stronger than that of phosphoric acid. It has strong reducibility and can easily reduce Ag ions to metallic silver, and can reduce sulfuric acid to sulfur dioxide. It has strong hygroscopicity and deliquescence, and is corrosive. Can cause burns. Irritating to skin. It is deliquescence when placed in the air and easily soluble in water. Decomposes above 160℃ to generate H3PO4 and PH3
R22 - Harmful if swallowed.
R35 - Causes severe burns.
S26 - After accidental contact with eyes, rinse immediately with plenty of water and seek medical advice.
S36/37/39 - Wear appropriate protective clothing, gloves and goggles or mask.
S45 - In case of accident or feeling unwell, seek immediate medical attention (show its label if possible).
As a raw material for the manufacture of plastic stabilizers, it is also used in the manufacture of synthetic fibers and phosphites
