摘要：

Solid-state H-1 and P-31 MAS NMR of trialkylphosphine and trialkylphosphine oxide probe molecules adsorbed on various porous solid acid catalysts, namely H-ZSM-5, H-MCM-22, H-Mordenite, H-USY, H-beta, H-MCM-41 and sulfated zirconia, have been studied. It is shown that, qualitative and quantitative information of the acid sites can be obtained when the 31 P NMR results are combined with the data obtained from P-31 elemental analyses.
