I know that formic acid will dehydrate upon heating to 100°C (under normal pressure) or adding sulfuric acid. What other catalysts can be used to induce this reaction?

  1. Activated alumina, silica, thoriated silica gel, phosphorus pentoxide-silica gel, aluminum phosphate, titanium dioxide

  2. Mixed titanium-vanadium oxide
