| 11. | However, this is the preferred alloy composition for production of Raney nickel catalysts currently in use.
|
| 12. | Commercially available Raney nickel has an average Ni surface area of 100 m 2 per gram of catalyst.
|
| 13. | Raney nickel is produced when a block of nickel-aluminium alloy is treated with concentrated sodium hydroxide.
|
| 14. | For this reason, commercial Raney nickel is available in both " active " and " inactive " forms.
|
| 15. | An alternative process operates in diluted ADN conditions using HMD itself as a solvent and Raney Nickel as catalyst.
|
| 16. | This catalyst, now commonly known as Raney nickel, was the subject of a patent he obtained in 1927.
|
| 17. | Raney nickel is notable for being thermally and structurally stable, as well has having a large Teller ) surface area.
|
| 18. | Even after reaction, Raney nickel contains significant amounts of hydrogen gas, and may spontaneously ignite when exposed to air.
|
| 19. | In the presence of Raney nickel, it undergoes dehydrogenation to 2-methylimidazole, which can then be further elaborated.
|
| 20. | "' Raney nickel "'is a solid catalyst composed of fine grains of a nickel-aluminium alloy.
