Abstract

Pyridine and 3-methyl pyridine are prepared by interacting acrolein with ammonia in the vapour phase at an elevated temperature in the presence of a catalyst prepared by impregnating a support material with a compound or compounds of boron, phosphorus and oxygen, the said support material comprising silica, alumina, or a mixture or combination thereof. The impregnation may be effected by use of an aqueous solution of boric acid and phosphoric acid followed by drying and calcinating the impregnated material. It is preferred to mix the ammonia and acrolein at at least 200 DEG C. prior to passing over the catalyst, which is suitably at 250 DEG to 500 DEG C. If desired an inert inorganic or organic gas or vapour may be employed as diluent. The acrolein reactant may be the substantially pure monomer or a reaction product containing it.
