Abstract:
1. A process for the production of methylpyridine from methylpiperidine, comprising contacting methylpiperidine with a dehydrogenation catalyst prepared by the process comprising (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 below 80° C. (d) calcinating the catalyst in air at a temperature between 80° C. and 200° C. sufficiently such that the catalyst resulting from steps (a) through (d) can be used in said process for at least 300 days when used at temperatures between 285°-310° C., and (c) activating the catalyst with hydrogen at a temperature between 250° C. and 320° C.
