| ホスフィン酸アンモニウム Usage And Synthesis |
化学的特性 | white crystals | 使用 | As catalyst in polyamide manufacture. | 一般的な説明 | White crystalline solid. Sinks and mixes with water. | 空気と水の反応 | Water soluble. Ammonium hypophosphite liberates spontaneously flammable phosphine at about 240°C [Mellor 8:880 1946-47]. | 反応プロフィール | Ammonium hypophosphite liberates spontaneously flammable phosphine at about 240°C [Mellor 8:880 1946-47]. Some inorganic materials, such as hypophosphites, tend to form explosive mixtures with perchloric acid when hot [Analyst 84:215 1959]. | 危険性 | Evolves flammable and toxic fumes on heating. | 健康ハザード | Non-toxic or low toxicity unless heated to decomposition (240°C). | 燃焼性と爆発性 | Not classified | 純化方法 | Crystallise it from hot EtOH. |
