A ternary Rh complex catalyst highly active and stable in the hydrogenation of acrylonitrile–butadiene rubber†
Abstract
An Rh-based complex, T-Rh-PPh3, was developed through a facile one-step process. The T-Rh-PPh3 exhibited high activity and air stability in the hydrogenation of acrylonitrile–butadiene rubber. The enhanced air stability can be ascribed to the phenolic hydroxyl structures in tannin.
