| 摘要 |
The present invention provides an improved oxidation catalyst composition containing a catalytically effective amount of silver and a rubidium promoter deposited on a carrier, which rubidium metal promoter provides a quantity of rubidium at least 5 mumole and less than 60 mumole per gram of catalyst composition. The catalysts of the invention are deposited on carriers such as alpha-alumina and silver-bonded calcium carbonate. The invention is also directed to a process for the oxidation of olefins, which process involves reacting the olefin with oxygen in the presence of a catalyst composition having a catalytically effective amount of silver and a rubidium promoter deposited on a carrier, wherein said rubidium metal promoter provides a quantity of rubidium of at least 5 mumole and less than 60 mumole per gram of catalyst composition. |
