Abstract
Tetrahydroisohumulones are prepared from beta-acids without using objectionable organic solvents by treating the beta-acids to form desoxytetrahydrohumulones which are dissolved in an aqueous alcoholic caustic solution and then oxidized and isomerized with an oxygen-containing gas in the presence of metallic ion to form the desired tetrahydroisohumulones.
