SAPO-11
Product Detail
SAPO-11 is a medium-pore silicoaluminophosphate molecular sieve with tunable acidity. It’s made up of regularly alternating AlO4, PO4, and SiO4 tetrahedra. Its 10-ring channels are unidirectional and non-intersecting and have elliptical pore apertures of approximately 0.39 × 0.63 nm (literature value). The medium acid sites and catalytic activity are generated by the isomorphic substitution of silicon for aluminum and phosphate on the surface. The result is a SAPO-11 molecular sieve with high potential for selectivity and catalysis.
As with every material sold by ACS Material, SAPO-11 meets exceptionally high standards for quality, purity, and performance. Researchers and engineers all over the world trust ACS Material to provide the best quality molecular sieves.

Applications
SAPO-11 belongs to one dimension pore structure. This type of micro pore zeolite has low activity in cracking and disproportionation, high activity in isomerization and alkylation, excellent anticokability. It has high selectivity of para-position in isomerization of xylene and methylation of toluene. It can be used as catalyst or catalyst carrier for dewaxing via isomerization, selective hydrogenation, cracking, condensation of alcohol and aldehyde, etc.
