One-step gas-phase synthesis of butadiene from formaldehyde and propylene on aluminum (AlP), zirconium (ZrP), and niobium (NbP) phosphates with the pore volumes of 0.51, 0.25, and 0.19 cm3/g, respectively, was studied for the first time. The physicochemical properties of the catalysts were studied by X-ray fluorescence analysis, low-temperature nitrogen adsorption, X-ray diffraction analysis, scanning electron microscopy, temperature-programmed NH3 desorption, IR spectroscopy of adsorbed pyridine, and 31Р MAS NMR. Evaluation of the catalytic properties of the phosphates showed that they can be ranked in the following order with respect to the formaldehyde conversion and target product (butadiene) formation selectivity: AlP < ZrP < NbP, which correlates with metal electronegativity series. The СН2О conversion on the most active NbP was 4.5%, and the molar selectivity of the butadiene formation was 45.3%.
