Abstract
A method for preventing the degradation of a catalyst during storage of the catalyst and prior to using the catalyst in a chemical process comprising treating the catalyst with an antioxidant and storing the treated catalyst until further use. The stabilized treated catalyst may be used in a process for producing organic chemicals such as in a process for producing bisphenol A.
