Abstract

<jats:title>Abstract</jats:title> <jats:p>A highly basic solid catalyst was obtained by dispersing potassium salts such as KNO3, K2CO3 over alumina at the surface density of 10-15×1018 K+ ions m−2 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.</jats:p>
