Abstract

1,193,341. Pyridines. IMPERIAL CHEMICAL INDUSTRIES Ltd. 26 April, 1968 [11 May, 1967; 25 Aug., 1967 (2); 13 Oct., 1967; 18 Oct., 1967; 24 Oct., 1967 (2); 8 Nov., 1967 (2); 9 Nov., 1967; 17 Jan., 1968 (2); 22 Jan., 1968], Nos. 21877/67, 39167/67, 39168/67, 46873/67, 47462/67, 48221/67, 48222/67, 50885/67, 50886/67, 2532/68, 3311/68, 16284/68 and 16285/68. Heading C2C. Pyridine or 3-methylpyridine is prepared by reacting ammonia in the vapour phase at an elevated temperature with acrolein as the sole aldehyde reactant in the presence of molecular oxygen and a catalyst comprising silica-alumina. The catalyst may also contain boron phosphate, or one or more oxides or salts of magnesium, zirconium, zinc, thorium, copper, iron, cobalt, titanium, lead, cadmium or chromium, and may be used as a fluidized or static bed. The reaction mixture may also contain a gaseous diluent, e.g. nitrogen or steam. If desired the acrolein may be prepared in a first stage by the catalytic oxidation of propene in the vapour phase, the gaseous mixture obtained being used without separation of the acrolein.
