| Hazard Information | Back Directory | [Chemical Properties]
Crystalline solid. Decomposes at 218C. Insoluble in water; soluble in hydrochloric acid, weak sulfuric acid, and sodium hydroxide solution. | [Uses]
In acrylonitrile polymer fiber finishes. | [Hazard]
Decomposes to toxic phosphine. | [Flammability and Explosibility]
Flammable | [Synthesis]
During synthesis, if the pH is not well controlled, it is highly likely that Al(OH)3 will be obtained;
If one simply mixes two solutions of aluminum sulfate and sodium hypophosphite, it seems to be prone to double hydrolysis:
Al(3+) + 3H2PO4(-) + |
