Supported K-salts as a New Solid Base Catalyst
A highly basic solid catalyst was obtained by dispersing potassium salts such as KNO<SUB>3</SUB>, K<SUB>2</SUB>CO<SUB>3</SUB> over alumina at the surface density of 10-15×10<SUP>18</SUP> K<SUP>+</SUP> ions m<SUP>−2</SUP> and activating them at 773-873 K in vacuo; the activity for the double bond isomerization of cis-but-2-ene of thus obtained catalysts was one order of magnitude higher than that of MgO, a typical solid superbase.
