IMPROVED EPOXIDATION PROCESS |
摘要 |
The selectivity of an olefin epoxidation process catalyzed by a titanium- containing zeolite is improved by performing the epoxidation in the presence of a non-ionic tertiary amine or tertiary amine oxide additive. For example, when hydrogen peroxide is reacted with propylene in the presence of TS-1 titanium silicalite to form propylene oxide, non-selective ring-opening reactions of the propylene oxide are suppressed when low concentrations of 2 ,6- lutidine or other substituted pyridines are added to the hydrogen peroxide feed.
