Property

Commodity: Phosphorous Acid

Synonym: orthophosphorous acid

Molecular Formula: H3PO3

Molecular Weight: 82

CAS No.: 13598-36-2

UN: 2834

Hazard Class: 8

Boiling Point: 200 °C (Decomposes)
Solubility: Easily soluble in water and alcohol.
Phosphorous acid is a colorless crystal. It can be slowly oxidized to phosphoric acid in the air. When heated to 180 °C, it can be decomposed into phosphoric acid and phosphine (highly toxic). As a dibasic acid, it has slightly ber acidity than phosphoric acid. Phosphorous acid has b reducibility and can easily reduce Ag+ to metal silver. It can also reduce sulfuric acid to sulfur dioxide. It is corrosive and has b hygroscopicity.
Relative Density: 1.651 (21.1 °C)
Melting Point: 73.6 °C

Application

1. In industry and agriculture

The most important use of phosphorous acid is the production of phosphonates which are used in water treatment. Phosphorous acid is also used for preparing phosphite salts, such as potassium phosphite.

2. As a chemical reagent

Phosphorous acid is used in chemical reactions as a reducing agent that is somewhat less vigorous

than the related hypophosphorous acid.

Phosphorous acid is also used as nylon whitener, plastic thermometer, synthetic fiber in plastic industry; as materials for producing weedicide, bactericide and water stabilizer in pesticide industry.
