phosphorous acid is *8.5% *9%
CAS NO *********1 *5KG/BAG **0KG/BAG
phosphorous acid is mainly used in the production of phosphates,
synthetic
fibers and organophosphorus pesticides, etc.. It is also used in
producing high
performance water treating agent ATMP.
Phosphorous acid is a colorless crystal, relative Density: 1.**1
(*1.1 C);
melting Point: *3.6 C; moiling Point: **0 C (Decomposes); easily
soluble in
water and alcohol.
It can be slowly oxidized to phosphoric acid in the air. When
heated to **0 C,
it can be decomposed into phosphoric acid and phosphine (highly
toxic). As a
dibasic acid, it has slightly stronger acidity than phosphoric
acid. Phosphorous
acid has strong reducibility and can easily reduce Ag+ to metal
silver. It can
also reduce sulfuric acid to sulfur dioxide. It is hygroscopic and
has strong
hygroscopy.
