Abstract Porous phosphate heterostructure materials with zirconia galleries have been prepared. Their acid properties were studied via 2, 6-di-tert-butyl-pyridine adsorption, infrared spectra of pyridine adsorption and potentiometric titration. The samples prepared in alcohol media are more thermal stable than those prepared in aqueous media. They are very active and selective for the Prins condensation of β-pinene with paraformaldehyde ...
