主权项

1. A process for the production of a catalyst for the dehydrogenation of methylpiperidine to methylpyridine comprising in the order (a) to (d) the step of
(a) providing a carrier comprising 65-100 weight % silicon oxide and 0-35 weight % aluminium oxide, (b) impregnating the carrier with palladium, whereby the carrier is brought into contact with an aqueous solution of a palladium-ammonia-complex to obtain a catalyst, (c) drying the catalyst with air at a temperature between 20-60° C. and (d) calcinating the catalyst at a temperature between 80-200° C.
