Versuchsvorschrift
Yttrium nitrate hexahydrate 5.08 g was dissolved in 10.8 g of water, to provide an aqueous solution of yttrium nitrate. Fifteen (15.0) g of silica gel (CARIACT-30® manufactured by Fuji Devison) was impregnated with the solution prepared as described above and dried in air at 120° C., followed by a sequential calcination in air at 500° C. for 5 hours and in nitrogen at 500° C. for 5 hours. Thus, yttrium oxide supported on silica gel was obtained, which was labelled Catalyst (4). This support type catalyst contained 10 wt % thereof yttrium oxide, and had a specific surface area of 110 m2 /g.
