Acetylene Heterocyclisation Catalysts, Ammonia And Aliphatic Ketones

Abstract

The goal is to identify patterns and study the mechanism of synthesis of pyridine bases. The basic principles for the selection and preparation of active and selective catalysts for the synthesis of pyridine bases are proposed. 9 catalytic systems have been developed using oxides of a number of metals of variable valence. The physical and mechanical properties were studied: mechanical strength 37.3-50.2 kg/cm², specific surface area 132.6-278.2 m²/g, porosity 0.31-0.70 cm³/g , bulk density 0.60- 0.93 g/ cm³ ammonia and running time from 51 to 250 hours of the developed catalysts. The adsorption of acetylene on the surface of CA and HXA catalysts has been studied and certain regularities have been determined.
