Abstract

1,191,913. Pyridine bases. LEUNA-WERKE "WALTER ULBRICHT" VEB. 7 Nov., 1967, No. 50547/67. Heading C2C. A process for the conversion of pyridine bases to pyridine bases of lower molecular weight at increased temperatures, in the presence of air and on a catalyst which contains vanadium pentoxide on a carrier consists in carrying out the conversion in the presence of that quantity of air which contains at the most three times the stoichiometrically required amount of oxygen, on a catalyst containing up to 15% by weight of vanadium pentoxide on aluminium oxide which has been preheated to a temperature between 600‹ and 1000‹ C. and has a surface area between 150 and 10 m.<SP>2</SP>/gm. The catalyst may also contain cadmium, bismuth, nickel or cobalt oxides and the conversion may be carried out in the presence of water. Various methyl and ethyl pyridines are specified for use as starting materials. Examples are furnished.
