Product Introduction:

Orthophosphorus acid, inorganic compound, corrosive, easily soluble in water and alcohol, slowly oxidized to orthophosphoric acid in air. It is a white, water-soluble solid that reacts with water to produce phosphoric acid and hydrogen gas.

Orthophosphorus acid is decomposed into phosphine and orthophosphoric acid at 180°C. Orthophosphorus acid is a dibasic acid, and its acidity is slightly stronger than that of phosphoric acid. It has been found that the use of orthophosphorus acid can help to prevent the growth of bacteria and fungi on textiles.

Phosphorus acid is a compound that is used for the production of phosphor, which is an important component of explosives. Phosphorus acid can be obtained from the mineral phosphate.

Product Usage:

Orthophosphorus acid is widely used, mainly used as reducing agent, nylon whitening agent, also used as raw material of phosphite ester, pesticide intermediate and organic phosphorus water treatment agent, in addition to being used as industrial solvent, fertilizer even food additives.

It is a colorless and water-soluble solid that has many industrial uses. Phosphorus acid can be used to make phosphite, which is used as a raw material in the manufacture of plastic stabilizers.

Orthophosphorus acid has a variety of uses in different industries, but it is also well known for its use as a food additive. Phosphorus is present in many compounds in the production of fermented baked goods, including metal alloys such as phosphates and phosphonates used as detergents, pigments, flame retardants, corrosion-resistant steel, and phosphate glass.

Orthophosphorus acid plays a key role in the bakery industry as an alkali component of dough and is used to activate gluten in bread dough. It is also used as a leavening agent to add bulk and speed to yeast doughs such as bread.

Also a key ingredient in matches, it produces the extremely hot flames used to ignite the mixture of potassium chlorate and sulphur that produces matches. Orthophosphorus acid is commonly known as “friction fire”.

Used in the production of fertilizers, explosives and matches. It is also used in the production of detergents and cleaners.

Phosphoric acid has also been used as an antacid and stomach medicine for many years.

Phosphorus acids are also important in research laboratories as they can be used to synthesize compounds with different functionalities.
