Synthesis of a ceramic acid of tungstated alumina more active than silica-alumina for decompositions of cumene, ethylbenzene, and toluene
A ceramics acid, calcined at temperatures above 1000 degrees C, was obtained by impregnating aluminum hydroxide with aqueous ammonium metatungstate followed by calcining in air at 1000-1200 degrees C (1-5 wt% W); its acidity and catalytic activity for decompositions of toluene, ethylbenzene, and cumene are higher than those of silica-alumina.
