Phosphoric acid solution Use:
Phosphoric acid solution (H3PO4) is deliquescent and commercially the most important derivative of phosphorus, accounting for over 90% of the phosphate rock mined. The white rhombic solid is highly soluble in water and ethanol, and the concentrated aqueous solution is generally available for use.
Phosphoric acid solution is used in several industries other than the fertilizer industry. Most elemental phosphorus is converted into phosphoric acid for non-fertilizer use. There are two basic processes for the production of phosphoric acid.
Metaphosphoric acid is obtained by heating phosphoric acid until dense white fumes begin to appear. The product is highly deliquescent and glassy in appearance. Its salts are known as metaphosphates. Orthophosphoric acid is the most common and is used as an important phosphate ingredient in commercial fertilizers.
Phosphoric acid solution Storage conditions:
Storage precautions: Store in a cool and ventilated warehouse. Stay away from sparks and heat sources. The storage temperature shall not exceed 30 ℃ and the relative humidity shall not exceed 80%. Packaging sealing. It should be stored separately from flammable materials, alkalis, and active metal powders, and should not be stored together. The storage area should be equipped with appropriate materials to contain leaked materials.
Phosphoric acid solution toxicology data:
1. Acute toxicity LD50: 1530mg/kg (orally administered to rats); 2740mg/kg (rabbit transdermal)
2. Irritability
Rabbit transdermal: 595mg (24h), severe irritation.
Rabbit eye: 119mg, severe irritation.
3. Long term inhalation of 10.6mg/m3 in subacute and chronic toxic animals leads to an increase in serum protein content and a decrease in liver glycogen.
Phosphoric acid ecological data:
1. Ecotoxicity TLm: 138mg/L (96h) (mosquito fish)
2. There is currently no data on biodegradability
3. There is currently no data available on non biodegradability
