Abstract: Cyanopyridines of the formula are prepared by reacting acrolein and an alkanal or its acetal or ketone of the formula where R1, R2 and R3 may be identical or different and are each hydrogen, alkyl of 1 to 6 carbon atoms or aryl and R4 is alkyl and n is 0-11, with ammonia in the presence of a zeolite as a catalyst. The reaction is preferably carried out in the gas phase.

Abstract: Phenylacetaldehydes of the general formula I (I) where R1 to R5 are each independently of the others hydrogen, alkyl, alkoxy, halogen, haloalkyl, haloalkoxy or haloalkylthio, by catalytic rearrangement in the presence of a zeolite, are prepared by reacting an epoxy of the formula II or a phenylglycol of the formula III (II) (III) where Y and Z can be identical to or different from each other and are each hydroxyl, alkoxy, aryloxy or acyloxy, in the gas phase over a borosilicate zeolite catalyst at from 70 DEG to 200 DEG C. under reduced pressure.

Abstract: Tetrahydrofurans are prepared in the gas phase from butane-1,4-diols which may be substituted by alkyl, alkenyl and/or aryl radicals in the carbon skeleton. The reaction is carried out in the presence of a borosilicate and/or iron silicate zeolite, preferably of the pentasil type, as catalyst. Other catalysts which may be used are zeolites doped with alkali metals and/or alkaline earth metals and/or transition metals and/or rare earth metals and/or noble metals.

Abstract: Diamines of the formula (I) where R1, R2 and R3 are each hydrogen, alkyl, aryl, alkoxy, aralkyl or cycloalkyl and X is a group of the formula (CR4R5)m (II) where R4 and R5 have the meanings given above for R1 and m is from 1 to 12, are prepared by a process in which a diamine of the formula (III) where R1, R2 and X are the groups described above, is reacted with an olefin of the formula (IV) where R6 and R9 are each hydrogen or alkyl which is straight-chain in the alpha -position, in the presence of a zeolite as a catalyst.

Abstract: Aldehydes and ketones are prepared from epoxides of the formula where R1 and R2 are each alkyl, alkenyl, aryl, alkoxy or aralkyl and R3 has the same meanings or is hydrogen, by a catalytic rearrangement reaction in the presence of various catalysts, in particular zeolites of the pentasil type.
