Abstract
There is disclosed a method and composition for improving the fluidization characteristics and alleviating or inhibiting stickiness in a supported cupric chloride catalyst used as fluid bed catalyst in oxyhydrochlorinations reactions. The method involves the in situ preparation of the supported cupric chloride catalyst by addition of bare support on which no cupric chloride is deposited to the supported cupric chloride catalyst in the fluidized bed, or the use in the bed as the initial charge or as addition to the bed as makeup, of a composition which is a mixture of supported cupric chloride catalyst and bare support. In either event, as the oxyhydrochlorination proceeds, a portion of the cupric chloride on the supported catalyst becomes released therefrom and deposited in situ on the bare support, and stickiness of the cupric chloride containing catalyst particles to one another in the fluid bed is alleviated or inhibited.
