铝镍合金 (CAS No.12635-29-9)
- 中文别名
- 镍铝合金；Al-Ni合金；雷尼镍合金
- 英文名称
- Aluminum-nickel alloy
- 分子式
- AlNi
- InChIKey
- NPXOKRUENSOPAO-UHFFFAOYSA-N
- 所属类别
- 中间体
- 物化性质
- 灰色粉末或不规则颗粒，无固定熔点，不溶于水；在干燥空气中较稳定，长期暴露会轻微表面氧化。可溶于酸，能与碱金属氢氧化物溶液反应；经氢氧化钠溶液浸取除去部分铝后，形成高活性多孔镍骨架。
- 技术参数
- 镍含量约为45%-55%（质量分数），铝含量约为45%-55%（质量分数）。 外观为灰色粉末或颗粒，常见粒度为100-200目。 干燥失重不大于0.5%。 使用前需用10%-20%氢氧化钠溶液活化处理，以获得高催化活性。 应密封干燥保存，避免接触酸雾和潮湿环境。

Product Name:Aluminum-nickel alloy
English Name:Aluminum-nickel alloy
CAS No.:12635-29-9
Aliases:Nickel-aluminum alloy, Al-Ni alloy, Raney nickel alloy
Molecular Formula:AlNi
Physical Properties:Gray powder or irregular granules with no fixed melting point; insoluble in water. It is relatively stable in dry air but undergoes slight surface oxidation on prolonged exposure. It is soluble in acids and reacts with alkali metal hydroxide solutions; partial leaching of aluminum with sodium hydroxide solution yields a highly active porous nickel skeleton.
Uses:It is mainly used as a precursor for making Raney nickel catalysts. After alkali treatment, a highly active porous nickel is obtained, which is widely used in catalytic hydrogenation of olefins, alkynes, nitriles, nitro compounds, and other organic substrates. It can also be used as a nickel-base alloy additive or for preparing functional nickel coatings.
Technical Specifications:
Nickel content: 45%-55% (w/w); aluminum content: 45%-55% (w/w).
Appearance: gray powder or granules; typical particle size 100-200 mesh.
Loss on drying: not more than 0.5%.
Activate before use by treatment with 10%-20% sodium hydroxide solution to obtain high catalytic activity.
Keep sealed and dry, avoiding acid mist and humid environments.
