Abstract

This article discusses the study of the properties of heterogeneous catalysts for the
synthesis of acetonitrile. The process of condensation of acetylene with ammonia in the
presence of catalysts based on cadmium fluoride (?FA-1, ??FA-1, ?FA-2, ?ZA-1) has been
studied. The condensation of acetylene with ammonia has been studied in the presence of
cadmium fluoroaluminum catalysts . It was found that CFA after the first cycle of operation
is stabilized and the yield of acetonitrile decreases to a minimum and ranges from 5.0 to
10.0%. The main reaction products are mixtures of pyridine bases, among which 2- and 4-
methylpyridines predominate.It was found that as the catalyst is used, its activity gradually
decreases. The entrainment of metallic cadmium from the catalyst is observed.
