12-Tungstophosphoric acid/zirconia--a highly active stable solid acid--comparison with a tungstated zirconia catalyst.
A highly active and stable zirconia supported 12-tungstophosphoric acid catalyst is found to be 2-3 times more active in benzylation and acylation reactions than a tungstated zirconia catalyst.
