Abstract

PURPOSE:To attain to enhance yield, by a method containing compounds are dissolved in a solvent such as water or alcohol along with silicon, zirconium and aluminum-containing compounds and, thereafter, said compounds are hydrolyzed before baking. CONSTITUTION:Cerium, lanthanum and titanium-containing compounds (e.g., lanthanum oxide, lanthanum hydroxide, cerium hydroxide, cerium oxide, titanium oxide or titanate) are dissolved in a solvent such as water or alchol along with a component capable of being converted to a carrier or a promotor (e.g., silicon, zirconium and aluminum-containing compounds). Thereafter, an acid, alkali or a salt is added to the resulting solution to perform hydrolysis and, after drying, the obtained compounds is baked at 300-800 deg.C.

J). The yield of methylbenzyl ketone at a reaction humidity of 377°C was 82% based on the fed Fene/L/enzymatic acid.
