Abstract: The present invention provides a process for producing pyridines which are aromatically or heteroaromatically substituted in the 2 and 6 positions, in which aromatically or heteroaromatically substituted ketones having at least one reactive methylene group adjacent to the keto group, are reacted at temperatures from approximately 250 to 500.degree.C with aliphatic aldehydes in the gas phase in the presence of ammonia and in the presence of a catalyst having dehydrating and dehydrogenating properties.

Abstract: 1397153 Formaldehyde DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 7 Sept 1972 [14 Sept 1971] 41551/72 Heading C2C [Also in Division B1] Formaldehyde is produced by the oxidation of methanol with a free oxygen-containing gas at elevated temperature over a catalyst comprising oxidic compounds of molybdenum and iron in a weight ratio calculated as MoO 3 to Fe 2 O 3 of less than 10 to 1 and having a titanium dioxide content of up to 90% wt, wherein the catalyst has been prepared by a specified method of coprecipitation, shaping and calcining (see Division B1). The oxidation is effected at 275-310‹ C., using a methanol to air molar ratio of from 129 : 1 to 15 : 1 by passage of the gas mixture through a tubular reactor immersed in an oil bath.

Abstract: The present invention relates to a process for the production of pyridine and 3-methyl pyridine by catalytically reacting acrolein and acetaldehyde with ammonia in the gas phase, wherein the catalysts used are highly disperse aluminium silicates which contain from 3 to 30% by weight of aluminium oxide and which have a BET-surface of from 200 to 800 m2/g, a pore volume of from 0.4 to 1.0 cm3/g and a pore diameter of from 20 to 100.10-8 cm.
