A series of Al-P-O catalysts (Al-xP-O) were prepared using a P123-assisted one-pot method at different P/Al molar ratios and used for O-methylation of catechol and methanol. The influences of the P/Al molar ratio and P123 addition on catalyst structure and surface acid-base characteristics were investigated in detail. Increasing the P/Al molar ratio more favored crystalline aluminophosphate. The P123-assisted Al3+ and PO43− are known to be stabilized through weak steric force so that the formation of crystalline aluminophosphate could be inhibited at higher P/Al molar ratios. The results showed that the prepared Al-P-O catalysts possessed appropriate weak acid and weak base sites, which was beneficial to the reaction of catechol and methanol. The Al-1.1P-O catalyst synthesized with the assistance of P123 exhibited superior catalytic performances, with 52.5% catechol conversion and higher guaiacol selectivity of 97.6%.

AbstractThe characterization, pillaring ability and some catalytic properties of a saponite from the Vicálvaro deposit of Tolsa, located in Madrid have been studied. This mineral is associated with sepiolite in the same lacustrine environment. The raw saponite presents, as special characteristics, high specific surface area (>200 m2/g) and a high percentage of tetrahedral Al (90% of the total Al in the sample). Natural saponite gives rise to high conversions when used as a catalyst in the reaction of alkylation of benzene with 1-dodecene. Increased catalytic performances are obtained over the alumina-pillared saponite derivatives. These materials have also been tested in the cracking of gas-oil (microactivity test), giving good conversions and high selectivity towards the gasoline fraction, especially the pillared forms.
