Modernization of the Catalyst Composition for the Synthesis of Acrylic Acid Nitrile in Aqueous and Non-Aqueous Media

Аннотация

The effect of the components of the catalyst solution for the hydrocyanation of acetylene on the activity and selectivity of the process under liquid-phase conditions has been studied. The introduction of ZnSO 4 and ZnO additives into the shop catalyst did not give a positive effect under these conditions. Studies of catalysts in non-aqueous media lead to an increase in their activity and selectivity in comparison with aqueous media. It has been shown that the composition of the CuCl - NMP - DMF catalyst is characterized by high activity (up to 32 g / l.h.) and selectivity (83-90%), i.e. the activity of this composition is almost twice as high as compared to the water-based ones (12-18 g l.h.).
