Abstract
Methods are provided for producing epoxidation catalysts. The present methods are able to produce catalysts having the desired loading levels of catalytic species at a lower vacuum level (having a higher minimum residual pressure) than previously appreciated by the art, thereby providing equipment cost and time savings.
