Abstract
A possibility of using heterogeneous catalysts with a low silver content for the direct carb-oxylation of phenylacetylene by carbon dioxide was demonstrated. A comparative study of the efficiency of the heterogeneous Ag-containing catalysts on different oxide supports (F-γ-Al2O3, γ-Al2O3, TiO2, SiO2) revealed that phenylpropiolic acid in the highest yield (62.1%) was achieved on the 0.5% Ag/F-Al2O3 catalysts.
