agrochemical intermediate hosphorous acid is mainly used in the production of phosphates, syntheticfibers and organophosphorus pesticides, etc.. It is also used in producing highperformance water treating agent ATMP.Phosphorous acid is a colorless crystal, relative Density 1.651 (21.1 °C);melting Point 73.6 °C; moiling Point 200 °C (Decomposes); easily soluble inwater and alcohol.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 adibasic acid, it has slightly stronger acidity than phosphoric acid. Phosphorousacid has strong reducibility and can easily reduce Ag+ to metal silver. It canalso reduce sulfuric acid to sulfur dioxide. It is hygroscopic and has stronghygroscopy.agrochemical intermediateagrochemical intermediate
