Raney Alloy – Nickel Aluminum Powder – CAS 12635-29-9 – Catalytic Grade

Raney Alloy, CAS 12635-29-9, is a finely divided nickel-aluminum powder alloy commonly used as a precursor to Raney nickel, an active hydrogenation catalyst in organic synthesis. This alloy consists of aluminum and nickel in a reactive form and requires activation (typically via alkali leaching) to expose its catalytic surface.

Raney Alloy is ideal for those in chemical research, catalyst production, or academic labs seeking control over in-situ catalyst activation.

🧪 Common Applications:

• Precursor for Raney Nickel Catalyst

• Hydrogenation reactions in organic chemistry

• Research in heterogeneous catalysis

• Metal surface chemistry studies

• Teaching tool in inorganic synthesis labs
