  • Effective hydrogenation of carbon monoxide to ethylene glycol using rhodium-trialkylphosphine-nitrogen base catalyst: critical role of nitrogen base promoter in controlling selectivity
  • Add time:08/01/2019         Source:sciencedirect.com

    In the rhodium/alkylphosphine complex catalyzed hydrogenation of carbon monoxide, the reaction rate and the selectivity to ethylene glycol have been found to be much improved by the addition of nitrogen bases. Examination of the effects of a variety of nitrogen bases for Rh/P-i-Pr3 and Rh/P-n-Bu3 catalyst systems revealed the linear relationships between rate (to ethylene glycol and methanol) and pKa value of the nitrogen base. Use of these catalysts, allowed a space time yield of 280 g/l·h and a selectivity of ethylene glycol of 76% to be achieved.
