A liquid phase hydroamination (HA) of α,β‐ethylenic compounds with amines was investigated with TiO2 nanoparticlesstabilized 12‐tungstophosphoric acid (TPA) in SBA‐15. The catalysts were prepared by wet impregnation of TPA/TiO2 nanoparticles into the SBA‐15 and calcined at different temperatures. The characterization results reveal that the textural properties and the acidity of the prepared catalysts
