| abstract |
The present invention is for preparing an olefin oxide by reacting an olefin having at least 3 carbon atoms with oxygen in the presence of a catalyst composition containing silver and an alkali metal promoter deposited on a support. Wherein the alkali metal promoter is selected from the group consisting of potassium in an amount of at least 5 mmol / g, based on the weight of the catalyst composition, and lithium, sodium and mixtures thereof. The alkali metal is contained in an amount capable of increasing the selectivity and work. The invention also relates to a process for producing 1,2-diol or 1,2-diol ether using the olefin oxide so prepared. The invention further relates to a catalyst composition comprising silver deposited on a support and a cocatalyst. |
