Nuclear hydrogenation of n-aryl polyamides |
| abstract |
N-Alicyclic polyamides are prepared by nuclear hydrogenation of N-aryl polyamides using a metal catalyst. For example bis(4acetamidophenyl)methane is hydrogenated to bis(4acetamidocyclohexyl)methane using a rhodium catalyst. Treatment of the catalyst with acid increases its effectiveness; spent catalyst is reactivated by treatment with acid (e.g., sulfuric or acetic acid). The acid-treated catalyst is also useful for nuclear hydrogenation of N-aryl monoamides. |
