Mol 文件 : |
由于在酸性或碱性溶液中水解生成 H2S 或 HS- ,故在分析化学中常被用来代替有毒和臭味的 H2S ,作为金属阳离子的组试剂或沉淀试剂。所得沉淀性质较好,易于分离。此外,亦可用作铋的测定试剂。 制备方法:由乙酰胺与硫化铝加热、乙腈与硫化氢反应,或乙酰胺与 K3PS4 反应制取。 |

Organic reagents |
Because in acidic or alkaline solution hydrolysis produce H2S or HS -, so often in analytical chemistry was used instead of toxic and H2S smell, as metal cation group reagents or precipitation reagent. The precipitation properties is good, easy to separate. In addition, can also be used for the determination of bismuth reagents. Preparation: by acetamide and sulfide aluminum heating reaction with hydrogen sulfide, acetonitrile, or acetamide and preparing K3PS4 reaction. |
