Abstract

Pyridine or a substituted pyridine may be obtained by interacting an ether of 2-hydroxy-5,6 - dihydro - 2H - pyran or of a substituted derivative of 2-hydroxy-5,6-dihydro-2H-pyran with ammonia in the vapour phase at an elevated temperature in the presence of a catalyst comprising a noble metal. The noble metal, i.e. ruthenium, rhodium, palladium, osmium irridium, platinum, silver or gold, may be used in finely divided form on a carrier or support and the reaction may be effected at 200-500 DEG C. The ammonia may be employed in an amount of 1 to 20 moles per mole of ether, the reaction mixture may contain molecular oxygen, suitably in an amount of 0.1 to 1.0 mole per mole of ether, and other diluent gases or vapours, e.g. steam, may be present.
