Abstract
2 : 4 : 6 - Trimethylpyridine is prepared by heating ammonia with an excess of acetone by weight in the vapour phase at a temperature above 300 DEG C. in the presence of a silica/alumina catalyst. The weight ratio of acetone to ammonia is preferably within the range 2 : 1 to 15 : 1 and the temperature is preferably 400 DEG to 500 DEG C. The catalyst preferably contains 5 to 50 per cent by weight of alumina, the remainder of the composition being silica. The process may be operated batchwise or continuously, any unchanged starting material being recycled to the reaction zone. The product may be characterized as the picrate or picrolonate derivative.
