Abstract
Pyridine, methyl pyridines and methyl-ethyl pyridines are prepared by contacting a gaseous mixture containing acetaldehyde and ammonia at an elevated temperature with a catalyst containing a compound or compounds of boron, phosphorus and oxygen. The reaction mixture may also contain acrolein, preferably in an amount of 0.3 to 3.0 moles per mole of acetaldehyde, and/or diluent gases or vapours. It is preferably not to contact ammonia with acetaldehyde at a temperature below 200 DEG C., suitable reaction temperatures being between 250 DEG and 500 DEG C. The acetaldehyde and acrolein reactants may be added as such, in the form of a reaction product containing a reactant, e.g. the product of the catalytic oxidation of propene for acrolein, or a material giving rise to it under the reaction conditions, e.g. paraldehyde for acetaldehyde. The compound(s) of boron, phosphorus and oxygen is (are) preferably deposited on a support material, advantageously by impregnating the carrier with an aqueous solution containing boric and phosphoric acids and subsequently drying and calcining the impregnated material.
