Hence, actual amount of catalyst used in the next batch, was almost

sion of benzyl alcohol was decreased on fourth run and selectivity
of benzaldehyde was not affected (95%). This shows that the novel
sulfated Ti-SBA-15 (10) catalyst has good reusability.

dative catalytic activity of Ti-SBA-15 (10) and sulfated Ti-SBA-15 (10)
were tested for liquid phase oxidation of benzyl alcohol to benzalde-
hyde by using hydrogen peroxide as oxidant. It was observed that the
activity of the catalyst was increased to three fold by generation of
super acidic sites on the catalyst. The high (95%) selectivity of benzalde-
hyde is reported which was not affected by the acidity of catalyst. Oxi-
dation of various substituted benzyl alcohol such as p-chlorobenzyl
alcohol, p-methoxybenzyl alcohol, 4-nitrobenzyl alcohol and other
commercially imported molecules like cinnamyl alcohol, styrene, and
p-bromostyrene were also performed to evaluate catalytic activity.
Catalyst was recycled four times and small decrease in activity was
found which shows that sulfated Ti-SBA-15 (10) catalyst has good reus-
ability. It could be concluded that mesoporous sulfated Ti-SBA-15 (10)
catalyst has potential for oxidation reaction.
